Fair Value Gaps
Understand imbalance zones left by aggressive moves and how price often returns to fill them before continuing.
Core Theory
A Fair Value Gap is an inefficiency where price moved so aggressively that it left a void between the wick of one candle and the body of another. Price frequently returns to rebalance before continuing.
In a balanced market, price spends time at every level, allowing buyers and sellers to transact across the full range. When one side becomes overwhelmingly aggressive, price skips through levels so quickly that meaningful two-sided trade never occurs there. A Fair Value Gap is the chart signature of that skip: a three-candle formation in which the first candle's wick and the third candle's wick fail to overlap, leaving a price band that the middle candle traversed almost untouched.
The reason these voids matter is that they represent unfinished auction business. Participants who wanted to transact in that band never got the chance; those who were positioned against the move are underwater and looking for a better exit. When price later returns to the gap, it encounters that latent interest, which is why gaps so frequently act as support or resistance on the retest rather than as mere empty space.
Not every gap is worth trading. Quality depends on three factors: the size of the displacement that created it, whether that displacement broke structure, and whether the gap sits at a location that already matters — an order block, a higher-timeframe level, a prior range boundary. A gap formed by a violent, structure-breaking move into a daily demand zone is a high-probability zone. A gap left by an ordinary candle in the middle of a range is noise with a rectangle drawn on it.
The 50% level of a gap, often called the consequent encroachment, is a practical reference point. Statistically, many retracements reverse near the midpoint rather than filling the gap entirely, which makes it a sensible location for a first entry, a partial fill, or a partial profit target when trading in the opposite direction. Placing a stop beyond the far edge of the gap rather than at the midpoint accommodates this behaviour.
Gaps also have a lifecycle. A fresh, unmitigated gap carries the most information. Once price has traded fully through it, the imbalance is resolved and the zone loses most of its predictive value. Treating a filled gap as if it were still active is one of the most common ways this concept is misapplied.
Step-by-Step Execution
Work through these steps in order. Each one produces an input the next step depends on, which is what keeps the process repeatable under pressure.
- 1
Confirm the higher-timeframe bias
Only hunt bullish gaps in a bullish context and bearish gaps in a bearish context. Counter-trend gap trades fill and keep going far more often than they reverse.
- 2
Locate structure-breaking displacement
Scan for a candle that is visibly larger than its neighbours and that breaks a recent swing point. The gap created by such a move is the only kind worth marking.
- 3
Draw the gap precisely
For a bullish gap, draw from the high of the first candle to the low of the third. Mark the 50% midpoint inside the zone, since that is where most reactions begin.
- 4
Look for confluence before committing
The strongest zones stack an FVG with an order block, a prior support/resistance flip, or a higher-timeframe level. A gap alone is a decent location; a gap plus a block is a setup.
- 5
Enter on the retest, not on formation
Wait for price to return into the zone and produce a lower-timeframe rejection or structure shift. Place the stop beyond the far boundary of the gap plus a small buffer for noise.
- 6
Target the next imbalance or liquidity pool
Unfilled gaps in the direction of the trade and unswept swing extremes are the natural destinations. Consider taking partial profit at the prior structural high before the full extension.
Key rules
- Look for a three-candle pattern with the middle candle showing a strong imbalance.
- Trade the gap as support/resistance only in the direction of the HTF bias.
- Combine FVGs with order blocks for higher-confluence entry zones.
- Use the 50% fill level as a common target for partial profit.
Common Pitfalls
These are the failure modes that appear most often in real journals. Recognising them early is usually worth more than learning an additional setup.
Marking every gap on every timeframe
One-minute charts are full of gaps that carry no information. Restrict marking to fifteen-minute and higher, and only where displacement broke structure.
Assuming all gaps must fill
Gaps are probabilities, not obligations. In strong trends, price frequently leaves gaps unfilled for weeks, and waiting for the fill means missing the entire move.
Stopping at the midpoint
Because reactions often begin near the 50% level, a stop placed there is inside the noise band. The stop belongs beyond the far edge of the gap.
Trading mitigated gaps
Once a gap has been fully traded through, its imbalance is resolved. Re-entering on a second touch is generally trading a level that no longer holds resting interest.
Ignoring the reason for the displacement
A gap created by a liquidation cascade or a news spike behaves differently from one created by steady accumulation. Context around the candle matters as much as the candle.
Invalidation levels
- A full close through the FVG in the wrong direction invalidates the setup.
- Trading an FVG against a strong HTF trend reduces probability.
- Using FVGs on very low timeframes without structure context creates noise.
Real-World Examples
The confluence retest
SOL breaks a two-week descending trendline with a 6% four-hour candle, leaving a gap between 148.20 and 152.60 that overlaps a bullish order block at 149. Two sessions later price retraces to 150.40 — the gap midpoint, inside the block — and prints a fifteen-minute higher low. Long from 150.60, stop at 147.40 beneath the gap, target at the unswept high of 168 for roughly 5R. The gap alone would have been reasonable; the overlap with the block made it a plan trade.
The counter-trend gap that never held
During a sharp daily downtrend, a trader marks a bearish-context bullish gap on the one-hour chart and buys the retest expecting a bounce. Price pauses for two candles, then closes straight through and continues 9% lower. The gap was real; the context made it irrelevant. Gaps against the dominant flow are usually just brief pauses in an ongoing repricing.
