Trading Glossary
75 terms covering order flow and market structure concepts used across our educational guides.
A
Absorption
Order FlowWhen 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.
Asian Range
ICT ConceptsThe 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.
Accumulation
ICT ConceptsThe 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 ActionThe 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 FlowThe 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 StructureConfirmation 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 StructureA failed order block that flips from support to resistance (or vice versa) after being broken. Acts as a key level for entries on retests.
Buy-Side Liquidity
ICT ConceptsStop 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.
b-Shape
Market ProfileA 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.
C
Cumulative Delta
Order FlowA 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.
Change of Character (CHoCH)
Market StructureThe 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.
Correction Leg
Market StructureA 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.
Composite Profile
Market ProfileA 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.
D
Delta
Order FlowThe 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.
Delta Bars
Order FlowA 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.
Delta Profile
Order FlowA 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.
Demand Zone
Market StructureA price area where buying pressure previously overwhelmed selling, causing price to rally. When price returns to this zone, expect buyers to step in.
Distribution
ICT ConceptsThe 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.
Displacement
ICT ConceptsA strong, impulsive price move characterized by large-bodied candles that shows clear institutional commitment. Displacement creates FVGs and confirms that Smart Money is active.
Discount Zone
Price ActionThe 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.
D-Shape
Market ProfileA 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.
Double Distribution
Market ProfileA 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.
E
Equilibrium
Price ActionThe 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.
Excess
Market ProfileA 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.
F
Footprint Chart
Order FlowA 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.
Fair Value Gap (FVG)
Market StructureA 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.
G
Golden Pocket
Price ActionThe 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 StructureA swing high that is above the previous swing high. A series of higher highs indicates bullish momentum and an uptrend.
Higher Low
Market StructureA swing low that is above the previous swing low. Combined with higher highs, it confirms bullish market structure.
I
Imbalance
Order FlowA 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 StructureA sharp, directional price move that establishes or continues a trend. Characterized by large candles and strong momentum. Creates new swing points and breaks structure.
Inducement
ICT ConceptsA 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.
Initial Balance (IB)
Market ProfileThe 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.
IB High
Market ProfileThe highest price reached during the Initial Balance (first hour). Acts as intraday resistance. A break above IB High signals potential bullish extension.
IB Low
Market ProfileThe lowest price reached during the Initial Balance (first hour). Acts as intraday support. A break below IB Low signals potential bearish extension.
J
Judas Swing
ICT ConceptsA deceptive price move — typically during London Open — that sweeps liquidity in the wrong direction before the real daily move begins. Named after the biblical betrayal because it tricks traders into the wrong side.
K
Killzone
ICT ConceptsSpecific time windows during the trading day when institutional activity is highest. The main killzones are London Open (2-5am ET), NY Open (7-10am ET), and London Close (10am-12pm ET).
L
Lower High
Market StructureA swing high that is below the previous swing high. A series of lower highs indicates bearish momentum and a downtrend.
Lower Low
Market StructureA swing low that is below the previous swing low. Combined with lower highs, it confirms bearish market structure.
Liquidity
ICT ConceptsResting orders in the market — stop losses and limit orders sitting at known price levels. Institutional traders need liquidity to fill large positions. Buy-side liquidity sits above price, sell-side below.
Liquidity Sweep
ICT ConceptsWhen 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.
London Open
ICT ConceptsThe killzone from 2:00 AM to 5:00 AM ET when European banks begin trading. Often creates the Judas Swing by sweeping the Asian session range before the real daily move begins.
M
Measured Move
Market StructureA 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 ConceptsThe 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.
Market Maker Model
ICT ConceptsThe Power of 3 applied to daily and weekly cycles. Identifies the accumulation range, waits for the manipulation sweep, then enters during the distribution phase targeting opposite-side liquidity.
Measured Move
Price ActionA price projection where Leg A's distance is added to the correction low to project Leg B's target. The -23.6% extension beyond 100% is Halsey's primary target in strong trends.
Market Profile
Market ProfileA charting method created by J. Peter Steidlmayer that organizes price data by time using TPO letters. The resulting profile shape reveals where the market accepted value and where it moved through quickly.
N
NY Open
ICT ConceptsThe killzone from 7:00 AM to 10:00 AM ET — the highest volume session with the most reliable setups. Often defines the day's range and creates the real expansion move.
O
Order Block
Market StructureThe last opposing candle before an impulse leg. Marks the zone where the institutional order that initiated the move originated. A common entry point on retests.
Optimal Trade Entry (OTE)
ICT ConceptsThe ideal entry point during a retracement, typically at the 62-79% Fibonacci retracement level of the impulse move. Aligns with order blocks and FVGs for precision entries.
P
Point of Control (POC)
Order FlowThe price level with the highest total volume in a given period. Represents fair value — where the market attracted the most trading interest from both sides.
Power of 3
ICT ConceptsThe ICT framework describing how every significant move is structured in three phases: Accumulation (range), Manipulation (fake breakout / stop hunt), and Distribution (real directional move).
Premium Zone
Price ActionThe upper half of a swing range (above the 50% equilibrium level). Price is expensive relative to fair value. Look for short entries in premium, not longs.
Poor High
Market ProfileA profile high that lacks a single-print tail — multiple TPO letters at the extreme instead of a clean rejection. The auction is incomplete and price tends to revisit the level.
Poor Low
Market ProfileA profile low that lacks a single-print tail — multiple TPO letters at the extreme instead of a clean rejection. The auction is incomplete and price tends to revisit the level.
Profile Shape
Market ProfileThe overall shape of a completed session profile. Common shapes include D-shape (balanced), P-shape (rally), b-shape (sell-off), double distribution (repricing), and elongated (trend day).
P-Shape
Market ProfileA profile shape that is fat at the top and thin at the bottom, indicating a rally or short-covering session. The POC sits in the upper portion. Check delta to confirm whether it was real buying or short covering.
R
Range Extension
Market ProfilePrice movement beyond the Initial Balance High or Low. A range extension signals that one side is taking control of the session. The 1x IB rule projects the first target by adding the IB width to the breakout side.
S
Stacked Imbalance
Order FlowThree or more consecutive price levels with imbalances in the same direction. Marks zones where institutional traders committed significant size, creating reliable support or resistance.
Swing High
Market StructureA local peak on a chart where price reversed lower. The highest point between two lower candles on either side. Marks a level where sellers previously overpowered buyers.
Swing Low
Market StructureA local trough on a chart where price reversed higher. The lowest point between two higher candles on either side. Marks a level where buyers previously overpowered sellers.
Supply Zone
Market StructureA price area where selling pressure previously overwhelmed buying, causing price to drop. When price returns to this zone, expect sellers to defend it.
Squeeze
Market StructureA period of low volatility compression, typically identified by contracting Bollinger Bands or Keltner Channels. When the squeeze releases, it often produces an explosive directional move.
SSL Cloud
Market StructureA trend-following indicator that combines moving averages to create a colored cloud on the chart. Green indicates bullish trend; red indicates bearish trend.
Sell-Side Liquidity
ICT ConceptsStop losses from long buyers and sell stop orders sitting below price action, typically below equal lows or swing lows. When price sweeps these levels, it triggers a burst of sell orders that institutions buy into.
Smart Money
ICT ConceptsInstitutional traders — banks, hedge funds, and market makers — who have the capital and information to move markets. ICT methodology focuses on identifying and trading with Smart Money activity.
Swing Leg
Price ActionA single directional price movement from one swing point to the next. Can be an impulse leg (with trend, fast) or a correction leg (against trend, slow). Legs are measured in points to project future targets.
Single Print
Market ProfileA price level on the Market Profile where only one TPO letter appears — the market visited that price during only one 30-minute period. Single prints represent initiative activity and act as support or resistance when revisited.
T
TPO
Market ProfileTime Price Opportunity — a single letter on a Market Profile chart representing one 30-minute period at a specific price level. Letters stack horizontally to show how much time the market spent at each price.
U
Unfinished Business
Order FlowAn incomplete auction where the high or low of a footprint bar shows zero volume on one side. Price tends to revisit these levels to complete the two-sided trading process.
V
Value Area
Order FlowThe range of prices where approximately 70% of total volume traded during a session. Defined by the Value Area High (VAH) and Value Area Low (VAL) around the POC.
Value Area High (VAH)
Order FlowThe top of the Value Area — the highest price within the zone where 70% of volume traded. Acts as resistance. When price breaks above the VAH, the market is repricing higher.
Value Area Low (VAL)
Order FlowThe bottom of the Value Area — the lowest price within the zone where 70% of volume traded. Acts as support. When price breaks below the VAL, the market is repricing lower.
Volume Profile
Order FlowA histogram showing the total volume traded at each price level over a defined period. Reveals where the heaviest trading occurred and where price is likely to find support or resistance.
VWAP
Order FlowVolume Weighted Average Price — the session's average price weighted by volume. The institutional benchmark for fair value. Price above VWAP = buyers in control. Price below = sellers in control.
