ICT Volume Imbalance — Complete Guide

The ICT volume imbalance (VI) explained — the body-to-body gap between two adjacent candles. The FVG vs VI distinction, the 3-type imbalance spectrum (LV, VI, FVG), bullish vs bearish VI, context-dependent analytical roles, and TradingView marking.
The ICT price imbalance family has three members. The fair value gap — a three-candle wick-to-wick gap with moderate institutional backing, primarily an entry zone. The liquidity void — a single-candle body traverse with minimal backing, primarily a fill target. And the volume imbalance — the body-to-body gap between two adjacent candles whose open/close ranges do not overlap. The VI sits between FVG and LV in both backing intensity and fill speed: more structure than a void, less than a full FVG.

Key takeaways

  • The VI zone = the gap between C1’s close and C2’s open. Bodies do not overlap. Wicks may overlap.
  • “Volume” does not mean traded volume — it refers to the imbalance in committed price action between two adjacent candles.
  • FVG = wick-to-wick, 3 candles, displacement candle backs the zone. VI = body-to-body, 2 candles, partial backing.
  • Context-dependent role: fill target within displacement moves, or precision entry reference at PD array boundaries.
  • Imbalance intensity spectrum: LV (most intense, fastest fill) → VI (intermediate) → FVG (least intense, slowest fill).

What is an ICT volume imbalance?

Definition

  • An ICT volume imbalance (VI) is a price zone that forms when two adjacent candles have body ranges (open to close) that do not overlap — C1’s close and C2’s open are separated by a gap in the committed price range. The VI zone is between C1’s close and C2’s open. Unlike an FVG (wick-to-wick gap across three candles), the VI is specifically a gap in the open/close ranges of two consecutive candles. The wicks may overlap — the gap is in the committed price action only.

Volume imbalance vs fair value gap — the precise distinction

VI vs FVGICT
Volume imbalance (2-candle body gap) vs fair value gap (3-candle wick gap) Two panels. Left: volume imbalance — two adjacent candles with overlapping wicks but a gap between their bodies (C1 close and C2 open). Right: fair value gap — three candles with no wick overlap between C1 high and C3 low, displacement candle C2 in the middle.

Body gap vs wick gap. Left: volume imbalance — two adjacent candles with wicks overlapping (full ranges touch) but bodies separated (C1 close to C2 open = VI zone). Right: fair value gap — three candles with no wick overlap between C1’s far wick and C3’s near wick. The differentiator: candle count (2 vs 3), boundary type (body vs wick), and wick overlap (present in VI, absent in FVG).

Bullish vs bearish volume imbalance

Bullish volume imbalance
C1 close < C2 open — gap UP in body terms

VI zone: C1 close (lower) to C2 open (upper). Wicks may overlap. Filled when price retraces bearishly into the zone from above. Role: fill target within displacement or entry reference at a PD array boundary.

Bearish volume imbalance
C1 close > C2 open — gap DOWN in body terms

VI zone: C2 open (lower) to C1 close (upper). Filled when price rallies bullishly into the zone from below. Same context-dependent role.

The ICT price imbalance intensity spectrum

IMBALANCE SPECTRUMICT
The ICT price imbalance intensity spectrum: LV, VI, FVG Three stacked bars from most intense to least: Liquidity Void (within 1 candle, minimal backing, fastest fill, fill target), Volume Imbalance (between 2 candles, partial backing, intermediate fill, context-dependent), Fair Value Gap (between C1 and C3, moderate backing, slowest fill, entry zone). MOST INTENSE → LEAST INTENSE · FASTEST FILL → SLOWEST FILL · WEAKEST BACKING → STRONGEST BACKING LIQUIDITY VOIDwithin 1 candle · minimal backing · fastest fillfill target single large candle body traversed with no opposing flow VOLUME IMBALANCEbetween 2 candles · partial backing · intermediatecontext role body-to-body gap — committed price action skipped between candles FAIR VALUE GAPbetween C1 & C3 · moderate backing · slowest fillentry zone wick-to-wick gap with displacement candle institutional order flow
Three imbalances, three positions. The LV is the most intense (gap within a single candle, minimal backing, fills fastest). The VI is intermediate (gap between two candle bodies, partial backing). The FVG is the least intense but has the strongest institutional backing from the displacement candle, fills slowest, and serves as the primary entry zone.

Why volume imbalances fill — the equilibrium logic

The same equilibrium-return logic that drives FVG and LV fills applies: a VI represents a price range where committed (body) price action did not occur — a gap in the two-sided commitment that characterises normal price discovery. Participants who wanted to transact at the VI prices place resting orders within the zone. When price returns, the fill occurs as these orders execute. The VI fills at an intermediate speed: faster than an FVG (less institutional backing to resist the retracement) but slower than an LV (more directional commitment than a void).

Fill target vs entry reference — the context-dependent role

The VI’s analytical role depends on its context. As a fill target: within a Phase 3 displacement move with no adjacent structural PD array, the VI marks a price range the AMD retracement will return to fill before establishing the next extreme. As an entry reference: when a VI boundary coincides with a key PD array (OB, FVG, structural level), the VI boundary provides precision entry pricing within the broader PD array context — where the PD array provides the structural backing the VI alone lacks. Always identify context before deciding the VI’s role.

How to mark a VI on TradingView

Find two adjacent candles with a body gap

C1’s close and C2’s open must not share a price. Minimum gap: 5 pips on EUR/USD. The wicks may overlap — only the body ranges matter.

Draw the rectangle on the body gap only

From C1’s close (one boundary) to C2’s open (other boundary). Do NOT extend the rectangle to the wick extremes — the VI zone is the body gap, not the full candle range.

Use a distinct visual style

Light amber or yellow tint with a dashed border, labelled “VI.” This distinguishes VIs from FVGs (teal/coral solid) and prevents misclassification during live sessions.

Apply the minimum size filter

Discard micro-gaps below 5 pips on EUR/USD (or equivalent on other instruments). Many FVG community indicators include VI as a toggleable sub-type — enable it and apply the minimum.

Common mistakes

Confusing VIs with FVGs

The single most common classification error. Check: 2 candles or 3? Body boundaries or wick boundaries? If wicks overlap but bodies do not → VI. If wicks do not overlap across a 3-candle pattern → FVG.

Using VIs as primary entry zones without PD array backing

VIs have partial backing — less institutional support than FVGs. A standalone VI entry without OB, FVG, or structural confluence has lower probability. Use VIs as precision references within a broader PD array context, not as standalone entries.

Drawing the VI zone to the wick extremes instead of the body gap

The VI is the body-to-body gap. Drawing to the wicks creates an incorrectly wider zone that overlaps with the wick area — which is NOT part of the VI. Mark body boundaries only.

Marking every tiny body gap as a VI

Apply the minimum size filter (5 pips EUR/USD). Micro-gaps are routine candle-to-candle variance, not meaningful imbalances. The gap should also be proportionally significant relative to surrounding candle body sizes.

FAQ — ICT volume imbalance

What is an ICT volume imbalance? +
A price zone between two adjacent candles whose body ranges do not overlap. Zone = C1 close to C2 open. Wicks may overlap. “Volume” refers to the imbalance in committed price action, not traded volume.
VI vs FVG? +
FVG: 3-candle, wick boundaries, displacement-backed, higher backing, slower fill, primary entry. VI: 2-candle, body boundaries, partial backing, faster fill, context-dependent. If wicks overlap but bodies don’t → VI.
VI vs liquidity void? +
LV: within 1 candle, minimal backing, fastest fill, fill target. VI: between 2 candles, partial backing, intermediate fill, context-dependent. VI sits between LV and FVG on the spectrum.
Entry zone or fill target? +
Context-dependent. Within displacement with no PD array: fill target. At a PD array boundary: entry reference within the broader context. Always identify context first.

Conclusion — the VI completes the imbalance family

The volume imbalance completes the ICT price imbalance family: three types, three formation mechanisms, three positions on the intensity spectrum. When scanning a chart: identify FVGs first (highest backing, most reliable entry zones), LVs next (most visually obvious, use as fill targets), then significant VIs last (body gaps at PD array boundaries as precision entries, or large displacement-phase body gaps as fill targets). Each type occupies a specific position in the analytical priority sequence — none supersedes the others, each complements the two.
