Core Market Concepts
The fundamental building blocks. Master these before anything else.
Bid and Ask
Every price in trading has two sides. The bid is the highest price a buyer will pay right now. The ask is the lowest price a seller will accept. The gap between them is where the market lives. Understanding bid and ask is the first step to understanding how prices actually move.
Read the full explanation of bid and ask →
Spread
The spread is the gap between bid and ask. If the bid is $99 and the ask is $100, the spread is $1. Every time you enter a trade, you “pay” the spread. Tighter spreads mean cheaper trading. Wider spreads eat into your profits fast.
Read the full explanation of spread →
Volume
Volume is how much of something got traded in a given time. High volume means lots of interest. Low volume means nobody’s paying attention. Volume helps you spot when a move is real versus when it’s just noise.
Read the full explanation of volume →
Liquidity
Liquidity is how easy it is to buy or sell without moving the price. Liquid markets are like water: smooth and easy to navigate. Illiquid markets are like peanut butter: slow, messy, and you can get stuck. Beginners should stick to liquid markets.
Read the full explanation of liquidity →
Volatility
Volatility is how much prices jump around. Low volatility is calm and predictable. High volatility is wild and dangerous. High volatility can mean bigger profits, but also bigger losses. Know what you’re dealing with before you trade.
Read the full explanation of volatility →
Slippage
Slippage is when your actual fill price is different from what you expected. You clicked buy at $100 but got filled at $100.05. That 5 cents is slippage. It’s worse in fast markets and thin markets. Small but adds up.
Read the full explanation of slippage →
Gap
A gap is when a price jumps from one level to another without trading in between, usually between market sessions. Your stop loss won’t protect you from gaps. A stock can close at $50 and open at $45, skipping everything in between.
Read the full explanation of gaps →
Order Types
The different ways you can tell your broker what you want to do.
Market Order
A market order tells your broker to buy or sell right now at whatever price is available. Fast and guaranteed to fill, but you don’t control the exact price. Best used in liquid markets.
Read the full explanation of market orders →
Limit Order
A limit order only fills at your price or better. You might wait longer (or never fill), but you control the price. Most smart traders use limit orders to avoid bad fills.
Read the full explanation of limit orders →
Stop Loss
A stop loss automatically closes your trade if the price moves too far against you. It’s your safety net. Every trade should have one, set before you enter. Never trade without a stop loss.
Read the full explanation of stop loss →
Take Profit
A take profit automatically closes your trade when the price reaches your target. It locks in your win before greed can ruin it. Plan your exits before you enter, not during the heat of the trade.
Read the full explanation of take profit →
Trailing Stop
A trailing stop is a smart stop loss that moves with the price. As your trade wins, the stop follows it up. If the price reverses, the stop stays put. A great way to lock in profits while letting winners run.
Read the full explanation of trailing stop →
Fill
A fill is when your order actually executes. “I got filled at $50” means your order went through at that price. Partial fills happen when only part of your order executes. Understanding fills helps you avoid nasty surprises.
Read the full explanation of fills →
Positions and Sizing
Controlling how much you buy, sell, and risk.
Long Position
Going long means buying and hoping the price goes up. This is the standard, basic way most people think about trading. Buy low, sell high. The higher the price goes, the more you make.
Read the full explanation of long positions →
Short Position
Going short is the opposite. You make money when prices go down. You borrow something, sell it high, and buy it back lower. Risky but powerful. Beginners should learn about it carefully before trying.
Read the full explanation of short positions →
Lot Size
A lot is how much you’re trading. Standard lot, mini lot, micro lot, and nano lot are the standard sizes in forex. In stocks, it’s shares. In futures, it’s contracts. Your lot size controls how much you win or lose per pip or point.
Read the full explanation of lot size →
Position Size
Position size is how much you commit to a single trade. Small positions equal small wins and losses. Big positions equal big wins and losses. Smart traders calculate position size based on risk, not gut feeling.
Read the full explanation of position size →
Leverage
Leverage is borrowing money to trade bigger than your own cash allows. A little leverage helps experienced traders. Too much leverage is the number one reason beginner accounts blow up. It multiplies gains and losses.
Read the full explanation of leverage →
Margin
Margin is the money you put down to use leverage. Think of it like a security deposit. Initial margin opens the trade. Maintenance margin keeps it open. Fall below that, and you get the dreaded margin call.
Read the full explanation of margin →
Measurements
The tiny units that add up to big results.
Pip
A pip is the smallest standard price change in forex. For most currency pairs, it’s the 4th decimal (yen pairs use the 2nd decimal). Pip value depends on your lot size. Know your pip value before you trade or you’re flying blind.
Read the full explanation of pips →
Point
A point is a unit of price movement used across many markets. In stocks, 1 point equals $1. In futures, every contract has its own point value. In indexes, a point is just a number. Same word, different meanings. Know the rules for your market.
Read the full explanation of points →
Tick
A tick is the smallest amount a futures contract can move, usually a fraction of a point. In ES futures, 1 tick equals 0.25 points equals $12.50. Ticks and points together help you calculate risk precisely.
Read the full explanation of ticks →
Price Analysis
Reading charts and understanding what prices are saying.
Trend
A trend is the general direction prices are moving. Uptrends show higher highs and higher lows. Downtrends show lower highs and lower lows. Sideways trends go nowhere. The trend is your friend. Most successful trades go with the trend, not against it.
Read the full explanation of trends →
Support
Support is a price level where falling prices tend to bounce back up. Think of it as a floor. Buyers wait at support levels, hoping for cheaper entries. Support is one of the most important concepts in chart reading.
Read the full explanation of support →
Resistance
Resistance is the opposite of support. A price level where rising prices tend to stop and fall back. Think of it as a ceiling. Sellers wait at resistance. When resistance breaks, prices often rally fast.
Read the full explanation of resistance →
Candlestick
A candlestick is a chart format that shows the open, high, low, and close for a time period in one visual. Green or white candles mean prices rose. Red or black candles mean prices fell. Almost every trader uses candlesticks.
Read the full explanation of candlesticks →
Chart Patterns
Chart patterns are shapes formed by price action that some traders believe predict future moves. Head and shoulders, double tops, triangles, flags. Some patterns work. Others are imagination. Know the difference.
Read the full explanation of chart patterns →
Moving Average
A moving average is a line that smooths out price action by averaging recent closing prices. The 20-day, 50-day, and 200-day are the most popular. Moving averages help you see the real trend beneath the noise.
Read the full explanation of moving averages →
Breakout
A breakout is when price pushes through a support or resistance level that has been holding it back. Breakouts often lead to fast, big moves. But beware of fake breakouts that snap right back.
Read the full explanation of breakouts →
Pullback
A pullback is a temporary move against the main trend. Like taking one step back while walking up a staircase. Pullbacks in uptrends are often great buying opportunities.
Read the full explanation of pullbacks →
Risk Management
The skills that separate lifelong traders from blown-up accounts.
Risk-Reward Ratio
The risk-reward ratio compares how much you could lose to how much you could make. Good traders want at least 1:2 (risk $1 to make $2). With better ratios, you can be wrong more often and still make money.
Read the full explanation of risk-reward ratio →
Drawdown
Drawdown is how far your account drops from its peak before recovering. It measures the pain of trading. Big drawdowns kill accounts and motivation. Keeping drawdowns small is more important than maximizing profits.
Read the full explanation of drawdown →
Balance vs Equity
Balance is the money from your closed trades. Equity is your balance plus or minus open trade performance. They match when you have no open trades. Equity tells the truth. Balance can be misleading when you’re holding losers.
Read the full explanation of balance and equity →
Expectancy
Expectancy is the average result per trade over time. Positive expectancy means you make money. Negative means you lose. Measuring expectancy honestly tells you if your strategy actually works.
Read the full explanation of expectancy →
Edge
An edge is any advantage that makes you profitable over many trades. Without an edge, you’re just gambling. The most important question in trading: what’s my specific edge?
Read the full explanation of trading edge →
Risk of Ruin
Risk of ruin is the chance your strategy will blow up your account. Small risks per trade keep risk of ruin low. Huge risks per trade make blow-ups almost guaranteed. Protect the downside first.
Read the full explanation of risk of ruin →
Breakeven
Breakeven is the price where you’d exit with zero profit or loss. Moving your stop to breakeven after a winner starts is a popular technique. It creates a risk-free trade.
Read the full explanation of breakeven →
Liquidation
Liquidation is when your broker force-closes your position, usually during a margin call. You don’t choose the timing or price. Usually happens at the worst moment. Never let your account get close to liquidation.
Read the full explanation of liquidation →
Trading Styles
Different approaches based on how long you hold trades.
Scalping
Scalping means holding trades for seconds to minutes. Tiny profits per trade, but many trades per day. Super intense. Not recommended for beginners.
Read the full explanation of scalping →
Day Trading
Day trading means opening and closing all trades within the same day. You never hold overnight. Medium-fast pace. Requires focus during market hours.
Read the full explanation of day trading →
Swing Trading
Swing trading means holding for days to weeks, trying to catch bigger moves. Slower pace than day trading. Good for people with day jobs who can’t watch screens all day.
Read the full explanation of swing trading →
Position Trading
Position trading means holding for weeks to months. Closer to investing than trading. Least stressful style. Requires patience and big-picture thinking.
Read the full explanation of position trading →
Markets and Sessions
When and where you can trade.
Bull Market
A bull market is when prices rise for a long time. Everyone’s happy. The economy feels strong. Bulls attack by swinging horns upward. Bull markets can last years but always end eventually.
Read the full explanation of bull markets →
Bear Market
A bear market is when prices fall 20% or more over a long period. Scary and painful. Bears attack by swiping paws downward. Bear markets are also where the best long-term opportunities hide.
Read the full explanation of bear markets →
Market Hours
Each market has its own trading hours. US stocks: 9:30am to 4:00pm Eastern. Forex: 24 hours weekdays, organized into sessions. Crypto: 24/7. Futures: nearly around the clock. Know when your market is active.
Read the full explanation of market hours →
Earnings
Earnings are when companies report quarterly financial results. These reports cause huge price moves. Holding through earnings is like rolling dice. Many experienced traders avoid the risk entirely.
Read the full explanation of earnings →
Circuit Breaker
A circuit breaker is when an exchange pauses trading due to wild price moves. Individual stocks or whole markets can be halted. Halts feel awful when you’re stuck in a position, but they often prevent even worse panic.
Read the full explanation of circuit breakers →
Forex
The world’s largest market, trading currencies 24 hours a day. Foundations every forex trader needs.
Foundations
Currency Pairs
Forex always involves trading one currency for another at the same time. You’re never just “buying euros” — you’re always buying euros AND selling something else, like dollars. Currency value only exists relative to other currencies.
Read the full explanation of currency pairs →
Base and Quote Currency
Every pair has two parts: the base (first) and quote (second). EUR/USD = 1.0850 means it takes 1.0850 dollars to buy one euro. The base is what’s being priced; the quote is what it’s priced in.
Read the full explanation of base and quote currencies →
Major, Minor, and Exotic Pairs
Forex pairs come in three categories. Majors include USD and have tightest spreads (EUR/USD, USD/JPY). Minors are major currencies vs each other without USD. Exotics combine a major with an emerging market currency. Beginners should stick to majors.
Read the full explanation of major, minor, and exotic pairs →
Mechanics
Pip Value Calculation
Pip value depends on lot size, currency pair, and account currency. For USD-quoted pairs with USD account: $10 per pip per standard lot, $1 per mini, $0.10 per micro. Other pairs require conversion. Use calculators, not mental math.
Read the full explanation of pip value calculation →
Lot Size in Forex
Standard lot (100,000 units), Mini (10,000), Micro (1,000), Nano (100). Bigger lots = bigger pip values = bigger profits AND losses. Beginners should start with micro lots and graduate up as accounts grow.
Read the full explanation of lot size in forex →
Forex Sessions and Overlap
Four sessions: Sydney, Tokyo, London, New York. The London-NY overlap (12:00-17:00 UTC) sees 70% of daily volume — the prime time to trade major pairs. Different sessions favor different currency pairs.
Read the full explanation of forex sessions and overlap →
Strategy Concepts
Swap and Rollover
Daily interest charge or credit for holding positions overnight, based on the rate differential between the two currencies. Wednesday charges 3x normal swap to cover the weekend. Day traders never see swap; swing traders need to factor it in.
Read the full explanation of swap and rollover →
Carry Trade
Borrowing low-interest currency to buy high-interest currency, profiting from the rate spread daily. Looks easy but has asymmetric risk — earn slowly, lose fast. The 2008 yen unwind wiped out years of carry in months. Not a beginner strategy.
Read the full explanation of carry trade →
Brokers
Forex Broker Types
Three models: Market Maker (takes opposite side, conflict of interest), STP (routes to specific liquidity providers), ECN (network of competing providers, explicit commissions). Choose based on volume, account size, and trading style.
Read the full explanation of forex broker types →
ECN vs STP
Both avoid Market Maker conflicts but differ in cost structure. ECN: tight raw spreads + explicit commissions, best for active traders. STP: wider marked-up spreads, no commissions, simpler for casual trading. Volume threshold around 50 standard lots/month often determines best fit.
Read the full explanation of ECN vs STP →
Practical Brokerage and Execution
How brokers actually work, what trading really costs, and the rules that affect every account.
Costs and Routing
Commissions
Trading commissions are the visible fees brokers charge to execute trades. Most US stock and ETF trades are now “commission-free” — but that doesn’t mean costless. Brokers replaced commissions with PFOF, wider spreads, and other revenue streams. Options, futures, and forex still have commissions.
Read the full explanation of trading commissions →
Payment for Order Flow (PFOF)
PFOF is how “commission-free” brokers really make money. Brokers sell your orders to high-frequency trading firms (Citadel, Virtu) for fractions of a cent per share. Controversial but legal in the US, banned in UK, Canada, and EU. The implicit cost is small but real for active traders.
Read the full explanation of payment for order flow →
Order Routing
How your broker decides where to send your trade — exchanges, wholesale market makers, dark pools, or ECNs. Most retail orders go to wholesale market makers. SEC requires “best execution” but enforcement is imperfect. SEC Rule 606 disclosures show where your orders actually go.
Read the full explanation of order routing →
Direct Market Access (DMA)
DMA lets you send orders directly to specific exchanges, bypassing wholesale market makers and PFOF. Comes with explicit per-share commissions but provides Level II data, routing control, and faster execution. Best for active day traders, scalpers, and algorithmic traders. Available at brokers like Interactive Brokers Pro.
Read the full explanation of direct market access →
Account Mechanics
Margin vs Cash Accounts
Cash accounts use only your deposited money — simpler and safer. Margin accounts let you borrow from the broker, enabling short selling, complex options strategies, and same-day use of unsettled funds. Margin can lose more than you deposit and triggers PDT rule for active day traders.
Read the full explanation of margin vs cash accounts →
Pattern Day Trader (PDT) Rule
The PDT rule requires $25,000+ minimum equity for traders who make 4+ day trades within 5 business days in a margin account. Below the threshold, you’re restricted from day trading. Workarounds: cash accounts (with settlement constraints), futures, forex, multiple brokers, or building capital first.
Read the full explanation of the PDT rule →
T+1 Settlement
Trades complete one business day after execution. Changed from T+2 to T+1 in May 2024 to reduce risk and modernize the system. Cash accounts can’t reuse sale proceeds until settlement; margin accounts allow same-day use. Forex still settles T+2.
Read the full explanation of T+1 settlement →
Good Faith Violation & Free-Riding
Cash account violations from misusing unsettled funds. Good faith: selling new security before original sale settles. Free-riding: buying without funds, selling to “pay” for buy. Three good faith violations in 12 months = 90-day cash-only restriction. Free-riding can trigger immediate restrictions.
Read the full explanation of good faith violations and free-riding →
Tax Considerations
Wash Sale Rule
The wash sale rule disallows tax losses if you buy “substantially identical” securities within 30 days before or after the loss-generating sale. The disallowed loss adds to the cost basis of the replacement security. IRA wash sales can permanently lose the tax benefit. Critical for year-end tax-loss harvesting.
Read the full explanation of the wash sale rule →
Tax Lots (FIFO, LIFO, Specific ID)
Each purchase creates a separate tax lot. When you sell some shares, you choose which lots — affecting reported gains and taxes. FIFO sells oldest first (default at most brokers). LIFO sells newest first. Specific ID lets you choose for maximum tax optimization. Active traders should default to Specific ID.
Read the full explanation of tax lots →
Strategy Types
The major strategy categories traders use, from statistical approaches to event-based plays to fully automated systems.
Statistical and Quantitative Approaches
Mean Reversion
Mean reversion bets that prices that move too far from average will return to it. Buy when oversold (RSI under 30, lower Bollinger Band), sell when overbought. Works in range-bound markets, fails in strong trends. High win rate but occasional large losses make strict stops essential.
Read the full explanation of mean reversion →
Arbitrage
Arbitrage profits from price differences for the same asset across markets. Pure spatial arbitrage is dominated by HFT — completely inaccessible to retail. Slower forms (merger arbitrage, crypto cross-exchange) sometimes work for retail. Even “arbitrage” carries real risks; truly riskless profit is rare.
Read the full explanation of arbitrage →
Pairs Trading
Pairs trading goes long one security and short a related one (Coke/Pepsi, sector ETF/single stock), profiting from changes in their relative price relationship. Market-neutral by design. Hedge funds dominate the space; retail margins are thin after borrow costs and commissions.
Read the full explanation of pairs trading →
Seasonal Trading
Seasonal trading uses calendar patterns: “Sell in May,” Santa Claus Rally, January Effect, agricultural cycles. Stock seasonals have weakened over decades; commodity seasonals more reliable due to physical drivers (weather, harvests). Best as one input rather than primary strategy.
Read the full explanation of seasonal trading →
Event-Based Approaches
Gap Trading
Gap trading targets price discontinuities between session close and next open. Four gap types: common (often fill), breakaway (often continue), runaway (continue with trends), exhaustion (signal reversals). Strategy depends on identifying gap type. Volatility creates both opportunity and risk.
Read the full explanation of gap trading →
News Trading
News trading reacts to economic releases (NFP, CPI, FOMC), earnings, and breaking news. The release moment is dominated by professionals with millisecond infrastructure. Retail traders should generally trade post-event, not real-time. “Buy the rumor, sell the news” is real — markets often anticipate.
Read the full explanation of news trading →
Event-Driven Trading
Event-driven targets specific corporate events: mergers, spinoffs, bankruptcies, IPOs, restructurings. Hedge funds dominate the institutional space with research teams and legal expertise. Retail can access spinoffs (Greenblatt’s strategy) and smaller M&A with diversification across many situations.
Read the full explanation of event-driven trading →
Approach Frameworks
Systematic vs Discretionary
Systematic traders follow strict pre-defined rules; discretionary traders use judgment in real-time. Most successful traders blend both. Beginners typically benefit from starting more systematic. Risk management should typically be systematic regardless. The best approach is the one you can execute consistently.
Read the full explanation of systematic vs discretionary trading →
Algorithmic Trading
Algorithmic trading uses computer programs to execute trades automatically. Categories include execution algos (TWAP, VWAP), strategy algos, and market making. Python dominates retail and institutional. Platforms: TradingView, QuantConnect, MetaTrader. Overfitting backtests is the most common failure mode.
Read the full explanation of algorithmic trading →
High-Frequency Trading (HFT)
HFT is the extreme-speed subset of algorithmic trading — microsecond execution capturing fractions of a cent across millions of trades. Major firms: Citadel Securities, Virtu, Jane Street. Estimated 50%+ of US equity volume. Completely inaccessible to retail. Don’t try to compete on speed — focus on longer timeframes where HFT doesn’t dominate.
Read the full explanation of high-frequency trading →
Cryptocurrency
The fundamentals of crypto trading: what you buy, where you store it, how it trades, and the unique risks of leveraged crypto derivatives.
Foundations
Bitcoin and Altcoins
Bitcoin is the original cryptocurrency, the largest, and the most decentralized. Altcoins are everything else — thousands of projects ranging from major platforms (Ethereum, Solana) to memecoins to outright scams. Bitcoin dominance reflects capital flow between Bitcoin and altcoins. Most altcoins eventually fail; conservative allocations heavily weight Bitcoin.
Read the full explanation of Bitcoin and altcoins →
Stablecoins
Stablecoins are cryptocurrencies designed to maintain stable value (typically $1 USD). Three types: fiat-backed (USDT, USDC), crypto-collateralized (DAI), and algorithmic (mostly failed — UST collapsed in 2022). They serve as crypto’s “cash” — used for trading pairs, holding value, DeFi operations, and cross-border transfers. “Stable” doesn’t mean “safe” — issuer risks and de-pegging events are real.
Read the full explanation of stablecoins →
Market Cap and Circulating Supply
Market cap = price × circulating supply. It matters far more than per-coin price. A “cheap” $0.001 coin can have a larger market cap than a “expensive” $50,000 coin. Fully Diluted Valuation (FDV) uses maximum supply and reveals future dilution risk. Understanding market cap prevents the “1000x potential” mathematical impossibility traps.
Read the full explanation of market cap and circulating supply →
On-Chain vs Off-Chain
On-chain transactions are recorded on the blockchain — immutable, transparent, slower, costs gas. Off-chain happens outside (CEX trading, Lightning Network) — faster, cheaper, but requires trust. CEX trades update databases (off-chain); DEX trades execute via smart contracts (on-chain). True ownership requires self-custody on-chain.
Read the full explanation of on-chain vs off-chain →
Storage and Trading
Crypto Wallets (Hot vs Cold)
Wallets store the private keys that control your crypto, not the crypto itself. Hot wallets (online, convenient) versus cold wallets (offline, secure). Custodial (exchange holds keys) versus self-custody (you hold keys). The seed phrase is your master key — protect it carefully. “Not your keys, not your crypto” — exchange failures (FTX) demonstrated this principle dramatically.
Read the full explanation of crypto wallets →
CEX vs DEX
Centralized exchanges (Coinbase, Binance) hold your funds and match trades through traditional order books. Decentralized exchanges (Uniswap, Curve) are smart contracts where you trade directly from your wallet. CEX = ease of use, fiat ramps, customer support, but counterparty risk. DEX = self-custody, all tokens accessible, but gas fees and complexity.
Read the full explanation of CEX vs DEX →
Gas Fees
Gas fees pay validators for processing transactions. Ethereum gas = gas units × gas price (in gwei). Different networks have wildly different costs: Ethereum mainnet $5-100+, Layer 2s like Arbitrum $0.10-2, Solana fractions of a cent. Failed transactions still cost gas. L2 solutions have made crypto activity dramatically more affordable than during 2021’s congestion.
Read the full explanation of gas fees →
Derivatives and Leverage
Crypto Spot vs Futures
Spot trading buys actual cryptocurrency you own. Futures are contracts betting on price without ownership, typically with leverage. Spot has 100% maximum loss; futures can liquidate at smaller moves. Futures allow shorting; spot is long only. Beginners should start with spot — futures involve liquidation risk and funding costs that destroy unprepared accounts.
Read the full explanation of crypto spot vs futures →
Perpetual Swaps and Funding Rates
Perpetual swaps (“perps”) are crypto futures with no expiration. Funding rates (paid every 8 hours) keep them aligned with spot prices — longs pay shorts in bullish markets, shorts pay longs in bearish ones. Perps dominate crypto derivatives volume. Funding rates serve as sentiment indicators and as costs that erode leveraged positions over time.
Read the full explanation of perpetual swaps and funding rates →
Liquidations
Liquidation closes leveraged positions when losses approach margin. Higher leverage means closer liquidation prices: 10x liquidates at ~10% adverse moves, 100x at ~1%. Crypto’s volatility makes routine moves trigger liquidations at high leverage. Cascades amplify moves dramatically. Avoidance is fundamentally about leverage choice — use modest leverage (1-5x) and explicit stop losses.
Read the full explanation of liquidations →
Analysis Methods
Different ways to figure out what to trade.
Technical Analysis
Technical analysis means studying charts to predict future moves. Support, resistance, patterns, indicators. Assumes all information is already in the price. Most short-term traders focus on technical analysis.
Read the full explanation of technical analysis →
Fundamental Analysis
Fundamental analysis means studying the thing behind the price. For stocks, that’s company earnings and business health. For forex, economic data and politics. Longer-term traders use fundamentals more than short-term traders.
Read the full explanation of fundamental analysis →
Indicators
Indicators are math formulas applied to price data that show up as lines or shapes on your chart. RSI, MACD, Moving Averages, Bollinger Bands. Useful but not magic. Master one or two instead of using a dozen at once.
Read the full explanation of indicators →
Backtesting
Backtesting means testing your strategy on historical data to see how it would have performed. Past results don’t guarantee future ones, but if your strategy lost money in backtests, it’ll probably lose money live too.
Read the full explanation of backtesting →
Paper Trading
Paper trading is practicing with fake money using real market prices. Every beginner should paper trade for months before risking real cash. It’s free practice. Use it.
Read the full explanation of paper trading →
Trading Psychology
The invisible force that decides your success. More traders fail from psychology than from strategy.
📘 The Complete Trading Psychology Guide: We’ve written a full 19-chapter guide covering everything below in depth. If you’re serious about the mental side of trading, start there — it organizes all these concepts into a coherent course. Read the Complete Trading Psychology Guide →
Part 1: How Your Brain Actually Works (Biology)
Why Your Brain Isn’t Built for Trading
Your brain evolved for small tribes, physical threats, and pattern-based survival — the opposite of what trading requires. Understanding this fundamental mismatch is the starting point for everything else.
Read the full explanation of why your brain isn’t built for trading →
The Amygdala Hijack and Dopamine Loop
Two brain systems sabotage traders: the amygdala (fight-or-flight, creates panic) and the dopamine reward system (creates addiction to trading itself, not trading well). The neuroscience of why you make bad decisions in hot moments.
Read the full explanation of the amygdala hijack and dopamine loop →
Part 2: The Core Cognitive Biases
Loss Aversion
The biggest one. Losses hurt about twice as much as equivalent gains feel good. Why traders cut winners early and hold losers too long — it’s wired into your brain.
Read the full explanation of loss aversion →
Confirmation Bias
Why you “see” evidence supporting your position and unconsciously ignore contradicting signals. How this turns into holding trades way past where you should have exited.
Read the full explanation of confirmation bias →
Anchoring Bias
Why your entry price mentally becomes the “real” price of the stock. “I’ll sell when it gets back to breakeven” is pure anchoring — and it destroys exit decisions.
Read the full explanation of anchoring bias →
Recency Bias
Overweighting what just happened. Why three winning trades feel like an unbeatable streak and three losers feel like your strategy is broken — when neither is actually true.
Read the full explanation of recency bias →
Sunk Cost Fallacy
“I’ve already lost so much, I can’t sell now.” How past losses inappropriately drive future decisions, and why the market doesn’t care what you paid.
Read the full explanation of the sunk cost fallacy →
Overconfidence Bias
Why 80% of traders think they’re in the top 20%. How small wins create dangerous feelings of mastery, and why confidence usually peaks right before blow-ups.
Read the full explanation of overconfidence bias →
Hindsight Bias
The “I knew it all along” effect. How retrospective confirmation creates false confidence and corrupts your ability to learn from past trades.
Read the full explanation of hindsight bias →
Availability Heuristic
Why vivid memories get overweighted in your decisions. How recent dramatic events shape your probability estimates far beyond their actual statistical relevance.
Read the full explanation of the availability heuristic →
Herd Mentality
Social conformity applied to markets. Why crowds feel safe, and why that feeling is often most wrong at exactly the moments it’s strongest.
Read the full explanation of herd mentality →
Part 3: Dangerous Emotional States
Fear and Greed
The two emotions that move all markets and all traders. How to recognize which one has gripped you in the moment, and what to do about it.
Read the full explanation of fear and greed →
Tilt
The poker concept applied to trading. When losses accumulate and emotions override every rule you’ve made. How to recognize tilt and what to do about it.
Read the full explanation of tilt in trading →
FOMO
Fear Of Missing Out — the painful state of watching a market move without you. Why FOMO pushes traders into late entries, oversized positions, and rule violations, and how to resist it.
Read the full explanation of FOMO in trading →
Revenge Trading
Trying to “win back” money from the market after a loss. Why it almost always compounds losses rather than recovering them, and how to prevent the pattern.
Read the full explanation of revenge trading →
Part 4: Mental Skills That Actually Help
Discipline
Not willpower — systems. Why discipline isn’t about being stronger but about removing decisions from moments when your brain is compromised.
Read the full explanation of discipline in trading →
Patience
The unsexy superpower. Waiting for your setup instead of forcing trades. Why most beginners can’t do this and why it separates profitable traders from unprofitable ones.
Read the full explanation of patience in trading →

Additional Psychology Concepts
Overtrading
Taking too many trades, usually from boredom, excitement, or trying to recover losses. Each trade costs money in spreads and commissions. The best trade is often no trade. Patience pays.
Read the full explanation of overtrading →
Trading Psychology
Your mental state while trading. Often more important than your strategy. Fear, greed, hope, and desperation destroy accounts. Managing them is a lifelong practice.

Blow-Up
A blow-up is when a trader loses most or all of their account. Usually from excessive leverage, no stop loss, or emotional decisions. Your number one goal: never blow up. Protection first. Profits second.

Trading Plan and Process
The systems that make trading sustainable.
Trading Plan
A trading plan is your written rules for how you trade. Entry rules, exit rules, risk rules, routines. It’s the difference between being a trader and being a gambler. Don’t trade without one.

Trading Journal
Your trading journal is a log of every trade: entry, exit, size, reason, result, emotions, lessons. Traders who journal get better. Traders who don’t keep making the same mistakes forever.

Compounding
Compounding is when your gains earn their own gains. Over years, this becomes incredibly powerful. $10,000 at 20% per year becomes $619,000 in 25 years. But only if you don’t blow up first.
Read the full explanation of compounding →
Return and Yield
Your return or yield is how much your account grew as a percentage. If you start with $10,000 and end with $12,000, your return is 20%. Annual return is the most common way to compare strategies.

Sizing Up and Sizing Down
Sizing up means increasing your position size as confidence grows. Sizing down means decreasing it during drawdowns. Knowing when to do each is a skill. Many traders size up too fast or refuse to size down.

Options
Options are contracts that give you the right to buy or sell at a set price. Powerful tools, but complex. These are the basics every trader should know before attempting options trading.
Options
Options are contracts giving you the right — but not obligation — to buy or sell a stock at a specific price within a specific time. You pay a small premium upfront. Limited downside, potentially large upside. The foundation of a whole new set of trading strategies.

Call Option
A call option is the right to BUY a stock at a set price. You use calls when you think a stock will rise. Buyer pays a premium, gets upside if stock climbs above the strike, loses only the premium if it doesn’t. Cheaper and safer than buying stock directly for short-term bullish bets.
Read the full explanation of call options →
Put Option
A put option is the right to SELL a stock at a set price. You use puts when you think a stock will fall, OR to protect stocks you already own. Safer than shorting because your loss is capped at the premium paid. Also great as “insurance” for long-term holdings.
Read the full explanation of put options →
Strike Price and Expiration
Every option has a strike price (the price at which you can buy or sell) and an expiration date (the deadline to use it). Picking the right combination is critical. Wrong strike or wrong expiration turns correct market calls into losing trades.
Read the full explanation of strike price and expiration →
Implied Volatility
Implied volatility (IV) is the market’s expectation of future stock movement, baked into option prices. Higher IV means more expensive options. Lower IV means cheaper options. Ignoring IV is why many traders lose money on options even when right about direction.

Market Mechanics
Market structure, corporate actions, and trading venue concepts that affect how stocks behave.
Stock Split
A stock split divides each share into multiple smaller shares. Price drops proportionally. Total value unchanged. Companies do this to make shares more affordable to small investors. Reverse splits do the opposite — often a warning sign for struggling companies.
Read the full explanation of stock splits →
Dead Cat Bounce
A dead cat bounce is a temporary rally in a stock that’s in a strong downtrend. Looks like recovery is starting. Traps buyers hoping the bottom is in. Then the decline resumes. Recognizing dead cats saves you from catching “falling knives.”
Read the full explanation of dead cat bounce →
Dark Pool
Dark pools are private trading venues where big institutions trade large amounts of stock without revealing their orders to the public market. About 15-25% of US stock trading happens in dark pools. Controversial but legal. Retail traders can’t access them directly but can sometimes see their activity with delayed reporting.

Advanced Concepts Worth Knowing
Less critical on day one, but important as you grow.
Correlation
Correlation is how much two things move together. EUR/USD and GBP/USD often move similarly. Understanding correlation prevents accidentally doubling your risk by taking “different” trades that are really the same bet.

Hedge
A hedge is a trade that offsets risk in another position. Advanced stuff, but good to know the word. If you own tech stocks and worry about a crash, shorting a tech ETF is a hedge.

Swap / Rollover
A swap or rollover is a small fee or credit for holding trades overnight, mostly in forex. Usually small per night but adds up if you hold for weeks. Day traders never deal with swaps.

Risk-Free Rate
The risk-free rate is the return you could get with almost zero risk, like from government bonds. Any trading strategy should beat this. Otherwise, why trade? Just put money in safe bonds.
Read the full explanation of the risk-free rate →
Risk-Adjusted Return
Risk-adjusted return measures how good your returns are compared to the risk you took. Making 15% with low drawdowns is better than making 30% with huge drawdowns. Sharpe ratio is the most famous way to measure this.

Opportunity Cost
Opportunity cost is what you give up by choosing one thing over another. Every dollar in one trade can’t be in another. Smart capital allocation means thinking about what else you could do with your money.
Read the full explanation of opportunity cost →
Depth of Market
Depth of Market (DOM or Level 2) shows many levels of bids and asks with their sizes. Useful for short-term traders who want to see where the big buyers and sellers are waiting. Swing traders rarely need it.

The Big Picture
You now have access to a complete vocabulary that covers the vast majority of what you’ll encounter as a beginner trader. That’s a huge head start!
But here’s the honest truth: knowing these terms is just the beginning. The real skills in trading are:
- Risk management — how you avoid blowing up while hunting for your edge
- Having an edge — a real, measurable advantage that makes you profitable over time
- Trading psychology — the invisible force that decides if you can actually execute what you know
A trader who knows 20 terms but has iron discipline will crush a trader who knows 100 terms but gambles wildly.
My recommendation: don’t try to memorize everything at once. Pick the terms most relevant to what you’re doing right now, and really understand them. Come back to this glossary as needed. Bookmark it. Share it with fellow traders.
