An ICT fair value gap (FVG) is a three-candle price pattern in which the first and third candles’ wicks do not overlap, leaving an interval between them. A bullish FVG appears when the third candle’s low is higher than the first candle’s high; a bearish FVG appears when the third candle’s high is lower than the first candle’s low. Traders sometimes call these intervals imbalances, although an FVG on a chart is not direct proof of all trading activity or available liquidity at those prices.
Fair value gaps are widely discussed because they provide a clearly markable zone after a strong move. The danger is believing every zone must be revisited or must produce a reversal. This guide explains the geometry first, then shows how context, risk and backtesting matter more than the presence of a colourful rectangle.
What is a Fair Value Gap in ICT trading?
In ICT price-action terminology, a fair value gap is an interval left between two outer candles in a three-candle sequence. Candle two often shows directional momentum or displacement; candles one and three define the edges. The label does not mean that the market has a single objective “fair value” or that trading never took place within the price interval. It is a description based on the selected candle timeframe.
Because different price feeds and timeframes aggregate trades differently, a visible FVG can change or disappear when a chart interval changes. Therefore, always identify the timeframe on which the interval was formed. A 30-minute FVG should be defined from 30-minute candles; inspecting it on a five-minute chart can help study reactions but does not redefine its original boundaries.
How to identify a bullish FVG
A bullish fair value gap exists when the high of candle one lies below the low of candle three. The area between those two wick prices is the gap. Price moved upward across that interval during the three-candle sequence without the outer candles overlapping it. Many traders prefer a conspicuous middle candle, but that is a qualification for a particular trading model rather than the essential three-candle geometry.
Bullish FVG example
Consider three hypothetical consecutive candles. Candle one has a high of 1.1010. Candle two is a strong bullish candle. Candle three has a low of 1.1020. Since 1.1020 is greater than 1.1010, the price interval from 1.1010 to 1.1020 is the bullish FVG. These numbers illustrate how to mark a zone; they are not a current Forex quote or a prediction.
If candle three’s low were instead 1.1008, the first and third wicks would overlap and this strict bullish FVG would not exist. Resist drawing a gap merely because the centre candle looks large. The relationship between the outer wicks must satisfy the definition.
How to identify a bearish FVG
A bearish fair value gap exists when the low of candle one is above the high of candle three. The gap is measured from candle three’s high to candle one’s low. It describes the opposite directional geometry: a strong downward movement with no overlap between the relevant outer wicks.
Bearish FVG example
Imagine candle one has a low of 1.1090 and candle three has a high of 1.1080. The zone between 1.1080 and 1.1090 qualifies as a bearish FVG under the usual wick-to-wick definition. If price later retraces into the zone, a trader can observe the reaction, but should not assume sellers will defend it.
Entry rules based on a bearish FVG must still define the larger direction, required confirmation, invalidation point and the market conditions in which such entries are not allowed. A visually perfect gap during an opposing higher-timeframe impulse might be a poor candidate for a particular strategy.
Displacement and FVG: what is the connection?
Displacement describes a relatively energetic directional move compared with recent price action. It can produce the three-candle geometry of an FVG. Some ICT setups specifically look for displacement after a liquidity sweep and a lower-timeframe shift in structure. This context attempts to avoid selecting every tiny, random gap.
However, a big candle does not prove institutional buying or selling, and a gap does not prove the direction of the next move. Scheduled economic releases, reduced liquidity and changing spreads can all produce abrupt chart movement. Traders need to separate an observable impulse from a causal claim about who created it.
What does “mitigation” mean for a fair value gap?
Mitigation is commonly used to describe price revisiting a previously marked area. If price rises and leaves a bullish FVG, a later pullback into the zone is sometimes called a mitigation or rebalance. Some traders observe the nearest edge; others measure the midpoint (often called consequent encroachment in ICT education) or the far edge.
These levels are descriptive markers, not guaranteed support or resistance. An FVG can remain untouched for a long time, experience a shallow test, trade fully through its boundaries or be invalidated. If your system requires a first return after formation, later visits should be recorded as different setup types rather than silently merged into the same test group.
What is an inverse Fair Value Gap?
An inverse FVG (IFVG) is a term some ICT educators use for a gap that has been breached and is then interpreted as a potential area of opposite-side reaction. For example, a bullish FVG broken convincingly to the downside may later be watched as possible resistance. Exact failure and inversion rules differ across teaching systems.
For analytical consistency, document whether failure requires a candle close beyond the far edge, a particular minimum displacement or a retest. If these conditions are changed after the result is visible, the chart study becomes an exercise in hindsight rather than a legitimate test.
How to use FVGs with higher-timeframe analysis
- Identify the four-hour or daily condition. Decide whether price is trending, ranging or transitioning.
- Mark a higher-timeframe point of interest. Use a clearly documented order-block or FVG rule rather than drawing every zone.
- Wait for the area to be reached. Do not assume that a projected retracement must happen.
- Observe liquidity and confirmation. Some test models require a sweep, displacement and lower-timeframe CHoCH or BOS.
- Find the first qualifying FVG. Use the exact execution timeframe and formation criteria chosen in the plan.
- Define entry and invalidation. Include stop distance, spread, slippage and the maximum allowed loss before any order.
- Evaluate the outcome. Record non-entries, failed zones and missed retracements as well as successful examples.
This is a research workflow rather than a recommendation to place a live trade. Traders may use a one-hour context with three- or five-minute execution, or a 15-minute context with one-minute execution, but smaller intervals are noisier and more sensitive to costs. Those combinations should be compared empirically.
What makes an FVG more or less relevant?
Context can help filter candidate zones. Ask whether the gap formed after a recognised liquidity event, during a meaningful displacement, in the direction of a defined higher-timeframe thesis and with sufficient room before opposing structure. Then ask which timeframes and market sessions are included in the test.
These are filters to evaluate, not proven conditions that automatically create an edge. Testing two versions—one using all geometrically valid gaps and another applying stricter context—can show whether added rules improve realised expectancy after realistic transaction costs. A filter that selects only a few impressive charts is not evidence.
Worked example: a bullish gap that fails
Suppose price enters a four-hour demand area, dips below a visible intraday low and then rallies sharply through a five-minute swing high. The rally leaves a qualifying five-minute bullish FVG. A plan may specify a retracement entry at a chosen location inside that gap and an invalidation beneath the swept low. If price instead falls through the gap, breaks the swept low and continues lower, the thesis is invalid.
The failure is not an exceptional mystery; it is a normal possibility whenever a price-action hypothesis meets an uncertain market. Predefining the invalidation helps keep the analysis honest. The same price sequence should be used to study stop distance, actual fill assumptions, overnight exposure and the role of spreads. Never move the stop simply because the pattern looked compelling.
Common mistakes in FVG trading
- Marking a gap even when the outer candle wicks overlap.
- Assuming every FVG must be filled or must produce a bounce.
- Mixing the forming timeframe and execution timeframe without recording either.
- Ignoring whether the market is ranging or trending and whether the gap opposes the higher timeframe.
- Entering a first touch without any tested invalidation or confirmation rule.
- Claiming a large middle candle proves specific institutional behaviour.
- Evaluating only ideal historical screenshots while excluding invalidated gaps.
Frequently asked questions
What does FVG stand for in Forex?
FVG stands for fair value gap. In ICT terminology it commonly describes the interval between the non-overlapping wicks of candles one and three in a three-candle sequence.
Does every fair value gap get filled?
No. Price can remain away from the gap, return only partly or trade directly through it without a useful reaction.
What is a bullish FVG?
A bullish FVG appears when candle three’s low is higher than candle one’s high, creating a gap between those two prices.
Can an FVG be used as a standalone entry?
A trader could define such a rule, but a gap by itself does not establish positive expectancy. Any complete strategy also needs risk, invalidation and testing.
What is consequent encroachment?
It is the midpoint of an FVG used by some ICT educators as a reference level. Its presence does not imply that price must react there.
Is FVG the same as order block?
No. An FVG is defined by three-candle wick geometry, while an order block is a separately identified price area near a directional move; the latter’s definitions vary more.
Key takeaways
The FVG formula is relatively simple, but deciding when a gap matters requires more judgment and evidence. Learn the wick boundaries precisely, use timeframe-specific markings, consider market structure and liquidity, and measure both successful and failed examples. The purpose is to develop a repeatable decision process, not to predict certainty from chart patterns.
