Trading Glossary

75 terms covering order flow and market structure concepts used across our educational guides.

A

Absorption

Order Flow

When aggressive orders hit a price level but fail to move price, indicating large passive orders are absorbing the aggression. A key reversal signal on footprint charts.

Related:Footprint ChartBid x Ask

Asian Range

ICT Concepts

The price range formed during the Asian session (8:00 PM to 12:00 AM ET). Acts as the daily reference range — London and New York sessions target the Asian high and low for liquidity sweeps.

Related:KillzoneLondon OpenJudas Swing

Accumulation

ICT Concepts

The first phase of the Power of 3 cycle. Price consolidates in a tight range while Smart Money quietly builds positions. Creates liquidity on both sides of the range.

Auction Market Theory

Price Action

The framework stating that markets alternate between balance (rotation around fair value) and imbalance (trending). Balanced markets are range-bound; imbalanced markets trend directionally.

B

Bid x Ask

Order Flow

The two columns in a footprint bar showing volume traded at the bid (aggressive sellers) on the left and volume traded at the ask (aggressive buyers) on the right.

Break of Structure (BOS)

Market Structure

Confirmation that a trend change has occurred. Happens when price breaks beyond the next swing point after an initial Change of Character, establishing a new directional bias.

Breaker Block

Market Structure

A failed order block that flips from support to resistance (or vice versa) after being broken. Acts as a key level for entries on retests.

Related:Order BlockBreak of Structure (BOS)

Buy-Side Liquidity

ICT Concepts

Stop losses from short sellers and buy stop orders sitting above price action, typically above equal highs or swing highs. When price sweeps these levels, it triggers a burst of buy orders that institutions sell into.

Related:Sell-Side LiquidityLiquidity SweepEqual Highs

b-Shape

Market Profile

A profile shape that is fat at the bottom and thin at the top, indicating a sell-off or liquidation session. The POC sits in the lower portion. Check delta to confirm whether it was real selling or long liquidation.

Related:P-ShapeD-ShapeProfile Shape

C

Cumulative Delta

Order Flow

A running total of delta across the session, tracking the cumulative difference between aggressive buying and selling. Used to identify divergences between price and order flow.

Related:DeltaDelta Bars

Change of Character (CHoCH)

Market Structure

The first signal that a trend may be ending. Occurs when price breaks a key swing point in the opposite direction of the prevailing trend — the early warning before BOS confirms.

Related:Break of Structure (BOS)Swing HighSwing Low

Correction Leg

Market Structure

A pullback or retracement that follows an impulse leg. Moves against the trend, is typically slower and choppier, and provides the entry opportunity for the next impulse.

Related:Impulse LegMeasured Move

Composite Profile

Market Profile

A profile that combines multiple sessions into one, revealing the bigger-picture value areas and POCs. Composite levels carry more weight than single-session levels because they represent sustained institutional consensus.

Related:Point of Control (POC)Value AreaMarket Profile

D

Delta

Order Flow

The difference between ask volume and bid volume at a specific price level or for an entire bar. Positive delta indicates more aggressive buying; negative delta indicates more aggressive selling.

Related:Cumulative DeltaDelta BarsDelta Profile

Delta Bars

Order Flow

A chart overlay showing the net delta (ask minus bid volume) for each bar as a colored bar. Blue indicates positive delta; magenta indicates negative delta.

Related:DeltaDelta ProfileCumulative Delta

Delta Profile

Order Flow

A view inside each footprint bar showing the net delta at every price level, colored by direction. Reveals where buying or selling aggression was concentrated within the candle.

Related:DeltaDelta BarsFootprint Chart

Demand Zone

Market Structure

A price area where buying pressure previously overwhelmed selling, causing price to rally. When price returns to this zone, expect buyers to step in.

Related:Supply ZoneStacked Imbalance

Distribution

ICT Concepts

The third phase of the Power of 3 cycle. After manipulation sweeps liquidity, price reverses sharply in the true direction. Smart Money distributes their position into retail momentum.

Related:Power of 3AccumulationManipulation

Displacement

ICT Concepts

A strong, impulsive price move characterized by large-bodied candles that shows clear institutional commitment. Displacement creates FVGs and confirms that Smart Money is active.

Related:Fair Value Gap (FVG)Impulse Leg

Discount Zone

Price Action

The lower half of a swing range (below the 50% equilibrium level). Price is cheap relative to fair value. Look for long entries in discount, not shorts.

Related:Premium ZoneEquilibriumFair Value

D-Shape

Market Profile

A balanced, bell-curve-shaped profile — fat in the middle, thin at the extremes. Indicates a two-sided session where neither buyers nor sellers dominated. The POC is near the center of the range.

Related:P-Shapeb-ShapeProfile Shape

Double Distribution

Market Profile

A profile with two separate clusters of activity connected by a thin zone of single prints. Indicates the market repriced from one value area to another during the session, often triggered by a news event or catalyst.

Related:Single PrintProfile ShapeValue Area

E

Equilibrium

Price Action

The 50% level of a swing range — the midpoint between the swing high and swing low. Represents fair value. Price above equilibrium is premium; price below is discount.

Related:Premium ZoneDiscount ZoneVWAP

Excess

Market Profile

A single-print tail at the top or bottom of a Market Profile, showing strong rejection at the extreme. Excess confirms the auction at that price is complete — the market does not need to revisit.

Related:Single PrintPoor HighPoor Low

F

Footprint Chart

Order Flow

A chart that displays the volume traded at each price level inside every candle, showing bid and ask activity separately. It reveals the order flow hidden inside standard candlesticks.

Related:Bid x AskDeltaImbalance

Fair Value Gap (FVG)

Market Structure

A three-candle pattern where the wick of Candle 1 does not overlap with the wick of Candle 3, leaving a gap where only Candle 2 traded. This gap is a price inefficiency — the market moved so fast that two-sided trading never happened at those prices. Price tends to return to fill FVGs.

Related:Impulse LegOrder Block

G

Golden Pocket

Price Action

The 61.8% Fibonacci retracement zone — the most watched retracement level among institutional traders. Corrections that hold at the golden pocket typically produce the strongest measured move continuations.

H

Higher High

Market Structure

A swing high that is above the previous swing high. A series of higher highs indicates bullish momentum and an uptrend.

Related:Higher LowSwing High

Higher Low

I

Imbalance

Order Flow

A price level where one side overwhelms the other by a ratio of 3:1 or more. Buying imbalances show aggressive buyers dominating; selling imbalances show aggressive sellers dominating.

Impulse Leg

Market Structure

A sharp, directional price move that establishes or continues a trend. Characterized by large candles and strong momentum. Creates new swing points and breaks structure.

Related:Correction LegBreak of Structure (BOS)

Inducement

ICT Concepts

A smaller liquidity grab that lures retail traders into positions before the real sweep happens. Acts as bait — creates false confirmation that traps traders, building more liquidity for the actual move.

Related:Liquidity SweepManipulation

Initial Balance (IB)

Market Profile

The price range established during the first hour of the regular trading session (A and B periods). The IB width helps predict day type — narrow IBs produce trend days, wide IBs produce range days.

Liquidity Sweep

ICT Concepts

When price briefly pushes beyond a key level to trigger stop losses, then reverses. The signature of institutional activity — stops are triggered to create the liquidity institutions need to fill their orders.

M

Measured Move

Market Structure

A price projection where the distance of Leg A (impulse) is added to the correction low to project Leg B's target. Halsey's primary target is the -23.6% extension beyond the 100% level.

Manipulation

ICT Concepts

The second phase of the Power of 3 cycle. Price breaks out of the accumulation range in the wrong direction to sweep liquidity. This is the Judas Swing — the trap that provides institutional order fill.
