Fair Value Gap

A fair value gap is a visible three-candle price-action structure where a fast price move leaves limited overlap between the first and third candles. The gap marks a structural imbalance in the candle sequence, not a complete trading plan.

In a clean fair value gap, the middle candle shows displacement, and the first and third candles leave an observable boundary. The label can help describe where price moved through an area with compressed two-sided interaction, but it does not define trade permission, entry, stop placement, target logic, or a guaranteed return into the gap.

What Is a Fair Value Gap?

A fair value gap is a localized inefficiency inside a price sequence. It is usually identified by comparing the range of the first candle with the range of the third candle after a strong middle candle creates displacement.

The useful part of the concept is the boundary. Without a visible candle 1 to candle 3 separation, the reading becomes less precise. A large candle by itself is not enough. The structure needs the surrounding candles to show that price moved through an area without normal overlap.

What a Fair Value Gap Is Not

A fair value gap is easiest to misuse when the label is treated as a signal instead of a structural description. The pattern can identify an imbalance, but the label does not say what should be done with it.

How to Identify a Fair Value Gap

The basic identification step is to compare candle 1 and candle 3 around a displacement candle. If the first and third candles overlap normally, the structure is not a clean fair value gap. If a visible separation remains, the area can be read as a fair value gap candidate.

1. Find a strong middle candle that moves price away from the prior area.
2. Compare the high and low of candle 1 with the high and low of candle 3.
3. Look for a visible space between candle 1 and candle 3.
4. Check whether the displacement is clear or whether the move is choppy and overlapping.
5. Classify the reading as clean, weak, or invalid instead of assuming every candidate matters equally.

The structure is stronger when the boundary is easy to see without forcing the interpretation. It is weaker when the only reason for the label is a large candle, a tiny spacing difference, or a messy sequence with heavy overlap.

Bullish vs Bearish Fair Value Gap

A bullish fair value gap and a bearish fair value gap use the same three-candle logic, but the direction of displacement is different.

The bullish or bearish label describes the direction of the imbalance. It does not automatically mean continuation, reversal, or any specific trade action.

Why Fair Value Gaps Form

Fair value gaps form when price moves quickly enough that the candle sequence leaves limited overlap. This is often described as displacement because the middle candle carries price away from the prior area faster than a more balanced sequence would.

The structure may show that one side of the market was more aggressive during that short sequence. That interpretation should stay conditional. The chart can show displacement and reduced overlap; it cannot prove the exact intent of every participant behind the move.

The most useful reading is therefore observable: did price leave a clear three-candle boundary, or is the label being forced onto a normal volatile candle?

Fair Value Gap vs Classic Gap

A classic gap usually refers to a space between separate candles or trading sessions, such as a market opening above or below the prior session’s range. A fair value gap is usually read inside a candle sequence, where the first and third candles leave a visible separation around a displacement candle.

The difference matters because the two labels describe different chart features. Calling every classic gap a fair value gap, or every fair value gap a session gap, blurs the structure.

Fair Value Gap vs Imbalance and Liquidity Void

Imbalance is the broader idea. It describes a market sequence where price moves with uneven participation or limited two-sided interaction. A fair value gap is a narrower, more observable form of imbalance because it uses a specific three-candle boundary.

A liquidity void can also describe a fast movement through price with limited interaction, but the term is often broader and less tied to the exact candle 1 to candle 3 structure. The fair value gap label is more useful when the boundary can be identified directly.

Clean, Weak, and Invalid Fair Value Gaps

The strongest way to read a fair value gap is not to ask whether price later produced a desired outcome. The better diagnostic question is whether the original structure was visible, specific, and still meaningful after later price behavior.

This classification keeps the concept tied to observable structure. A clean label should come from the chart boundary, not from a later outcome or a preferred market story.

Common Fair Value Gap Misreadings

A fair value gap is often misread when the label is separated from the actual three-candle boundary. The safer approach is to keep each reading tied to visible structure rather than outcome, expectation, or trade logic.

Related Price Action Concepts

A fair value gap should stay separate from nearby imbalance and block concepts. It describes a three-candle imbalance boundary, while a breaker block focuses on a failed reference area that later may be read from the opposite side.

It is also different from a mitigation block, which focuses on a return into a prior reference area rather than the candle 1 to candle 3 gap boundary itself.

These concepts can appear near each other on a chart, but they do not mean the same thing. A fair value gap describes the three-candle imbalance boundary; role-flip, mitigation, and reference-area logic describe different chart behavior.
