Trading Glossary
Plain-English definitions of trading and investing terms, each with a worked example and what it looks like when it fails.
Most popular
IndicatorsWhat Is RSI (Relative Strength Index)?RSI scores recent up moves against down moves from 0 to 100. On SPY since 1994, RSI(14) crossing 70 or 30 was followed by results within chance of an ordinary day.
IndicatorsWhat Is Fibonacci Retracement?Fibonacci retracement divides one swing into fixed fractions. The levels are exact arithmetic; the swing you measure from is a judgment, and that is the method.
Moving averagesWhat Is a Moving Average?A moving average is the average closing price over the last N bars, redrawn every bar. Its slope shows the trend; its position acts as a moving level.
TradingWhat Is Scalping?Scalping trades minute-scale moves. On 60 SPY sessions in 2026, 6.54% of five-minute moves were no bigger than a round trip, and price traveled 11.5 times its net move.
RiskWhat Is a Margin Account?A margin account lends against your positions, so the broker can sell first. FINRA counted $1.45 trillion of margin debt in August 2026, up 37.19% in a year.
Moving averagesExponential Moving Average: Not FasterAn exponential moving average lets weight decay instead of stopping. It reacts sooner to new bars, yet its center of mass matches the simple average: 9.5 bars.
TradingWhat Is Day Trading?Day trading holds nothing overnight. Its bars are larger than a scalper's, so each round trip eats a smaller share: cheaper than scalping, dearer than holding.

Step 1How to Read a CandlestickA candlestick shows four prices for one period: open, high, low and close. What the body, the wick and the color each tell you, and what they cannot.
Step 2What Is Support and Resistance?Support and resistance are prices the market has stopped at before. They are bands rather than lines, and they swap roles once broken.
Step 3What Is Market Structure?Market structure is the pattern of highs and lows on a chart. It shows which direction the market currently agrees on, and the exact point where that ends.
Step 4What Is Risk Management in Trading?Risk management is deciding what a trade can cost you before you take it. It sets your stop, your position size, and the point at which the idea is over.

Smart money concepts 31

Smart moneyBreak of Structure (BOS), ExplainedA close through the last swing in the trend's direction. On SPY since 1993, the 20 sessions after one went much like any 20 sessions.
Smart moneyBreaker Block: A Level That Failed, Then HeldA breaker block is broken support that became resistance, renamed. Only the first retest has anything behind it, and in a range every level does this.
Smart moneyBuy-Side vs Sell-Side Liquidity: Where Each Side RestsBuy-side liquidity is the buy orders resting above an obvious high; sell-side liquidity is the sell orders below an obvious low. How ICT uses both.
Smart moneyChange of Character (CHoCH), ExplainedA change of character is the first close through a swing point against the trend. On SPY's daily chart, half of the 220 since 1993 were reversed by the next break.
Smart moneyWhat Is Daily Bias? (ICT)Daily bias is the direction a trader expects a session to lean. On SPY since 1993, a close past the prior high or low hinted at the next day's range, not its close.
Smart moneyDemand Zone: The Area a Move Started FromDrawn from the last down candle before a rise. The first return has the most behind it, and a wide zone is a guess with a box around it.
Smart moneyWhat Is a Fair Value Gap?A fair value gap is a three-candle pattern where the first and third candles do not overlap, leaving a band of prices that only one fast candle passed through.
Smart moneyHigher High: The Runs Are ShorterA swing high above the one before it. Which swings count is a threshold choice, and a long unbroken run of them is the exception rather than the pattern.

Moving averagesThe 200-Day Moving Average, Backtested as a FilterThe mean of the last 200 daily closes, used as a trend filter. On SPY since 1993, a dip rule filtered by it made +141.80% while holding made roughly +1,480%.
Moving averagesAdaptive Moving Average: One That AdjustsAn adaptive moving average speeds up in a straight move and slows in chop, steered by an efficiency ratio, which is worth plotting even without the average.
Moving averagesWhat Is a Death Cross?The 50-day average crossing below the 200-day. Named for drama, not for evidence - and it fires after the decline that caused it.
Moving averagesWhat Is a Double Exponential Moving Average?A moving average built to subtract its own lag. It turns sooner than an ordinary average, and it turns sooner on the false moves too.
- Moving averagesExponential Moving Average: Not FasterAn exponential moving average lets weight decay instead of stopping. It reacts sooner to new bars, yet its center of mass matches the simple average: 9.5 bars.
Moving averagesGolden Cross: Too Rare to Be a SampleThe 50-period average crossing above the 200. It is rare by design - which is why nobody, including this page, has a sample worth drawing a conclusion from.
Moving averagesWhat Is the Hull Moving Average?The Hull moving average turns sooner than a simple one: 3 bars after the high against 10. The cost is that it changes its mind more often in a quiet market.
Moving averagesMoving Average Crossover: Count the CrossesA moving average crossover is one average crossing another. The gap between the periods sets the signal count; a fast pair can demand many more decisions.

IndicatorsAcceleration Bands: Width From the BarAcceleration bands are set by each bar's own width, not by deviation. Bar width swings between quiet and busy regimes, so any fixed-width band is usually wrong.
IndicatorsAccumulation Distribution: Volume, SignedVolume signed by where the close sat inside its bar's range. One of the few indicators that is not pure price - and it is blind to gaps by construction.
IndicatorsWhat Is the ADX Indicator?ADX measures how strong a trend is, not which way it is going. It read 23.5 through the chop below and 38.2 through the run — and rose again on the way down.
IndicatorsAlligator Indicator: A Ribbon, ShiftedThe alligator indicator is three smoothed averages of the bar midpoint, shifted forward. Tangled lines say no trend; separated lines say a trend is running.
IndicatorsAnchored VWAP: The Anchor Is the Whole ToolA volume-weighted average price starting from a point you choose. The anchor is the entire tool - a different anchor gives a different line on the same chart.
IndicatorsWhat Is an Andrews' Pitchfork?Three parallel lines drawn from three pivots. The middle one is the point — price is expected to return to it, and often does not.
IndicatorsWhat Is the Aroon Indicator?Aroon measures how recently the high and low happened, in bars. Its input is time, not price — so it cannot tell a small new high from a large one.
IndicatorsAroon Oscillator: It Counts Time, Not PriceBars since the high, minus bars since the low. The Aroon oscillator measures time, not distance, which makes it the one truly unusual indicator on the menu.

Chart readingBearish Engulfing: Two Bars and a StoryA bearish engulfing is a red body that fully covers the green one before it. Common, picked by bar size, and meaningless until it beats the base rate.
Chart readingBullish Engulfing: Test It Against the Base RateA green body that completely covers the red one before it. Any claim for it has to beat the base rate - on the S&P 500, 53.1% of all days closed up.
Chart readingWhat Are Candlestick Patterns?Doji, hammer, engulfing: every named candle is a region of two numbers, body size and wick length. A 54-bar illustrative chart with none planted held sixteen.
- Chart readingHow to Read a CandlestickA candlestick shows four prices for one period: open, high, low and close. What the body, the wick and the color each tell you, and what they cannot.
Chart readingHow to Read a Trading ChartChart reading in four steps, in order, on a bare chart: which way the lows go, where price stopped, where price is now, and the price that says you were wrong.
Chart readingDragonfly Doji: A Day Given Back EntirelyA dragonfly doji opens and closes at the top of the range with only wick beneath. On a thin instrument the tiny body is a tick-size artifact, not indecision.
Chart readingFootprint Chart: The Bar Taken ApartA bar opened up and counted price by price, split by which side crossed the spread - what it shows, what it costs, and where it stops working.
Chart readingGravestone Doji: Too Few Events to JudgeA gravestone doji opens and closes at the bottom of the range with only wick above. It is too rare for any count of it to separate a signal from chance.

Chart patterns and price action 52
See all 52
Price actionABCD Pattern: A Mechanical Test on the S&P 500 Since 1970The ABCD pattern projects a second leg equal to the first. Coded on the S&P 500 since 1970, the CD leg landed within 10% of AB in 12% of swings.
Price actionAccumulation: The Range After the FallAccumulation is a sideways range after a fall. In 1,515 such ranges in 56 US stocks and ETFs, heavier up-day trading mostly marked where price sat in the range.
Price actionAscending Triangle: One Real Line, One DrawnA flat ceiling with a rising floor. The ceiling is a genuine level; the rising floor is two lows you picked - and it is taught as bullish but breaks both ways.
Price actionBear Flag: A Squeeze Looks the SameA sharp decline then a shallow drift upward, traded on the break lower. It looks identical to the start of a short squeeze, and shorts pay borrow costs.
Price actionWhat Is a Breakout?A breakout is price closing beyond a level that had contained it. Most of the work is deciding what counts as a break, and what to do when it proves not to be.
Price actionBull Flag: The Break Is a 20-Bar HighA sharp advance, then a shallow drift. The entry is a break to a multi-week high, and it has to beat the 59% of S&P 500 ten-day holds that rose anyway.
Price actionWhat Are Chart Patterns?A chart pattern is a named shape in price: a double top, a flag, a triangle. Underneath every one is a level, and the level is what actually does the work.
Price actionThe Named Chart Patterns, Defined ExactlyHead and shoulders, cup and handle, ascending triangle, rising wedge — each one stated as a condition you could check, and the single price it resolves to.

Volume and order flow 24

Order flowWhat Is a Dark Pool?A venue where large orders are not displayed before they fill. The trade still prints afterwards, so the secrecy is about timing, not existence.
Order flowWhat Are Dark Pools?Private venues where large orders trade without showing first. The prints reach the same tape, just later — which is why a dark print is history, not a signal.
Order flowDelta: How Much the Option Moves Per DollarDelta is the slope of the payoff line at the current price. Across an 80–120 sweep it runs from 0.08 to 0.90, which is why one option behaves so differently.
Order flowWhat Is Delta Divergence?Buying volume minus selling volume disagreeing with price. It needs tick data most charts do not have, and the classification is an assumption.
Order flowDepth of Market: The Ladder, and Its LimitsThe same order book drawn as a vertical ladder, built for futures where one exchange holds the whole book. The point is execution speed, not extra information.
Order flowWhat Is Float in Stocks?The float is the shares actually available to trade, fewer than shares outstanding. With a small float ordinary size moves price, and the exit is the thin side.
Order flowHidden Order: Size That Does Not ShowAn iceberg shows a slice and refills it silently. It is an ordinary exchange feature, not a trick - and it is why displayed size is a floor rather than a count.
Order flowWhat Is an Iceberg Order?An order that displays only part of itself and refills as each slice fills. The book understates what is there, which is the whole point of using one.

OrdersWhat Is the Ask Price?The lowest price anyone is currently willing to sell at. It is what you pay to buy, and it sits above the price on the ticker as often as not.
OrdersATR Trailing Stop: A Choice About TimeAn ATR trailing stop is measured in average true range, so it widens with the market. The multiple sets holding time: a wider trail stays longer and risks more.
OrdersWhat Is the Bid-Ask Spread?There are always two prices, and the gap between them is a fee you never get an invoice for. It is charged on the way in and again on the way out.
OrdersWhat Is the Bid Price?The highest price anyone is currently willing to pay. It is what you receive when you sell, and it is not the price on the ticker.
OrdersBracket Order: Both Exits, Decided FirstAn entry with a stop and a target attached, each canceling the other. Its value is behavioral - it makes you decide both exits before you are in the position.
OrdersBuy-In: Your Position Closed Without YouIn a buy-in, someone buys shares back for you at whatever the market asks, because a borrow was recalled or delivery failed. The risk short sellers forget.
OrdersWhat Is Central Counterparty Clearing?The arrangement that replaces a web of bilateral exposures with a single hub. It reduces total risk and concentrates what remains.
OrdersWhat Is a Circuit Breaker?A rule that halts trading after a set decline. The levels are published in advance, and your stop cannot fill while the market is halted.

OptionsAssignment and Exercise, ExplainedThe buyer chooses; the seller is allocated at random. Most short options simply expire, but a gap through the strike assigns the whole position at once.
OptionsBinary Option: The Payout Sets the OddsA fixed payout on a win, the whole stake on a loss, and a payout ratio set by your counterparty. The arithmetic and the regulatory position, plainly.
OptionsCalendar Spread: A Bet on StillnessSame strike, two different expiries. The near leg decays faster than the far one, so it makes the most when price sits still at the strike.
OptionsWhat Is a Call Option?A right to buy at a fixed price. The loss is capped at the premium and the breakeven is the strike plus what you paid — 104 on a 100 strike costing 4.
OptionsThe Cash-Secured Put, and When It Makes SenseYou are paid to accept an obligation to buy lower. It only works on something you actually wanted to own, because in a real decline you buy all the way down.
OptionsThe Covered Call, and What It Actually SwapsSelling a call against shares you own. It swaps unlimited upside for a payment today, and it leaves the entire downside exactly where it was.
OptionsCredit Spreads: A High Win Rate and a Small WinSell one option, buy a further one, keep the difference. A credit spread computed: +3 maximum gain, −7 maximum loss, so one full loss outweighs two wins.
OptionsDebit Spreads: Cheaper, With a CeilingBuy one option, sell a further one to cut the cost. Computed: −3 paid, +7 maximum gain, breakeven at 103 instead of 104 — cheaper entry, capped upside.

Risk, sizing and psychology 63
See all 63
RiskWhat Is Active Risk?How far a portfolio strays from its benchmark. Zero means you are the index — and paying an active fee for near-zero is the trap.
RiskWhat Is Alternative Risk Transfer?Moving insurance risk to capital markets instead of to another insurer. It exists because the capital markets are far larger than the insurance industry.
RiskAnti-Martingale: Add to WinnersIncrease size as a position works and never as it loses. The inverse of the martingale - and the stop must rise with each addition or it is not this.
RiskWhat Is Basis Risk?A hedge that does not quite match. The hedge and the holding move apart, and a perfect hedge has no basis risk and no upside either.
RiskBeta: Leverage You Did Not Ask ForThe slope of an asset's returns against an index. Above one is a levered position on the market that nobody wrote down as leverage.
RiskWhat Is Business Risk?The company itself failing. Unlike market risk this one can be diversified away — which is why the market does not pay you for holding it.
RiskWhat Is the Calmar Ratio?Return divided by the worst drawdown. It prices performance against pain, and a short history flatters it enormously.
RiskCommon Trading Mistakes: Size Ends AccountsSize is the mistake that ends accounts; the rest are expensive, not fatal. Common trading mistakes, ranked by the damage each does, not how often it is listed.

TradingWhat Is After-Hours Trading?The session after the close, where earnings land on purpose. Moves look large on very little volume, and they often do not survive the next open.
TradingAI Trading: What It Can and Can't DoAI trading uses machine learning or language models to research, code or place trades. What it can do, what regulators warn about, and 126 video titles measured.
TradingWhat Is Algorithmic Trading?Algorithmic trading forces you to state a rule completely. Even a one-line crossover entry leaves the exit, size and chart undecided until you write them down.
TradingArbitrage: The Textbook Version Is GoneBuying and selling the same asset in two places at once, in matched size. The textbook version carries no market risk; what is sold to retail is not that.
TradingAsian Session: The Range Everyone Else TradesThe thinnest of the three major sessions, which is why it so often builds a narrow range - and that range becomes the level the London methods trade against.
TradingAutomated Trading: Build the Kill SwitchThe signal is the small part. Hosting, logging, resting stops and the drift between tested and live fills are the half of the job nobody publishes.
TradingBacktesting: The Curve Is the SeductionBacktesting runs a rule over history to see what it would have done. Six named errors make results look better than reality, each easy to commit by accident.
TradingBacktesting Software: The Data DecidesBacktesting software replays trading rules over old prices. The data, the fill assumption and the cost model decide the answer, and all three sit on defaults.

FundamentalsAccounting Equation: Balancing Proves NothingAssets equal liabilities plus equity. The accounting equation holds because someone paid for every asset, and balanced books say nothing about correct numbers.
FundamentalsAnnual Report: Only Part of It Is AuditedAn annual report is a company's own account of its year. Most of it is unaudited; the last third is the accounts, and the notes run longer than the statements.
FundamentalsAssets: Carried at Cost, Not at WorthThings a company controls that should produce value. Most assets are carried at cost less depreciation, and a large asset base is not proof of a good business.
FundamentalsBalance Sheet: A Moment, Not a PeriodA balance sheet shows what a company owns and owes at one instant. Assets equal liabilities plus equity, always, and most assets sit at cost, not current worth.
FundamentalsBasic Earning Power Ratio: Formula and Worked ExampleBasic earning power = operating income / total assets. From SEC filings: Home Depot 19.88% and Lowe's 18.75% in their latest years, with Lowe's equity negative.
FundamentalsCash Flow Statement: Where the Money WentThree sections tracking actual money rather than accrued profit. The gap between net income and operating cash flow is the whole reading, and it runs both ways.
FundamentalsWhat Is the Cash-Flow-to-Debt Ratio?Operating cash flow against total debt. It asks how many years of actual cash it would take to repay what is owed, which profit figures cannot answer.
FundamentalsChart of Accounts: Design Decides ReportingThe list of accounts a company keeps. Its design decides what can be reported later - detail not captured at the point of entry cannot be recovered afterwards.

Bonds, rates and the economy 39
See all 39
Bonds and ratesWhat Is an Accrual Bond?A bond that pays no cash until the end. Interest is added to the principal instead, which makes it the most rate-sensitive structure there is.
Bonds and ratesWhat Is Adjusted Current Yield?Current yield corrected for the pull of the price back toward par. It sits between current yield and yield to maturity, and is more honest than either is alone.
Bonds and ratesWhat Is a Basis Swap?A swap exchanging one floating rate for another. It exists because two rates that should move together sometimes do not.
Bonds and ratesWhat Is a Bearer Bond?A bond owned by whoever physically holds it. No register, no name, no way to prove it was yours once it is gone.
Bonds and ratesWhat Is the Bid-to-Cover Ratio?Total bids divided by the amount on offer at an auction. It is the standard measure of how much demand a government bond sale attracted.
Bonds and ratesWhat Is Bond Convexity?What duration gets wrong. The price-yield relationship is a curve, so gains from falling rates exceed losses from rising ones — and the error favors the holder.
Bonds and ratesWhat Is Bond Duration?How far a bond's price moves when rates change. A duration of seven means roughly seven percent for every one percent move in rates.
Bonds and ratesWhat Is a Bond Fund?A pooled holding of many bonds that never matures. That single difference from an individual bond is the one that catches people out.

InvestingWhat Is Abnormal Return?The part of a return a model cannot explain. Change the model and the abnormality changes with it.
InvestingWhat Is Absolute Return?What you actually made, with no benchmark attached. Down five percent is down five percent, even if the index fell twenty.
InvestingAccount Growth: Deposits First, Returns LaterA small account grows mostly by deposits for years. Returns act on the balance, so compounding only becomes visible late.
InvestingWhat Is an Accredited Investor? The SEC Tests, Line by LineAn accredited investor meets an SEC test in Rule 501(a) and may buy private offerings. Its lines date from 1982 and 1988; SEC staff count 18.5% of US households over them.
InvestingWhat Is Active Return?Performance minus the benchmark. Beating a falling index is still a loss, and the choice of benchmark decides the answer.
InvestingArt Investing: A Market of Exactly OneBuying art in the hope it appreciates. It pays nothing, costs money to keep, and the published indices only count the pieces that actually sold.
InvestingBlackRock: It Manages, It Does Not OwnBlackRock is the largest asset manager, running other people's money, mostly in passive funds. Managing is not owning, and most claims about it miss that.
InvestingBRRRR Method: The Valuation DecidesBuy, rehabilitate, rent, refinance, repeat. The cycle recycles one deposit through several properties, and the refinance valuation decides whether it continues.

About these pages
Every entry is a full page rather than a dictionary line: what the term means, how it forms, a worked example read left to right, a figure from our study of 24,971 trading videos, and a section on what it looks like when the reading is wrong.
Start with the four foundation pages if you are new — candlesticks, support and resistance, market structure, risk management, in that order. Everything else assumes them.
746 terms written so far. Educational, not financial advice. Some links on this page earn a commission if you buy through them. It costs you nothing and it does not decide what appears here or in what order — how these pages are made is set out in our methodology.
