Fair value gap trading: how to find and trade an FVG
A fair value gap is a three-candle imbalance that price often comes back to fill. It is one of the most searched Smart Money Concepts, and also one of the most misused.

Smart Money patterns at a glance
Bearish
Change of Character
The first break against the trend — the earliest warning that control is shifting.
Bullish
Order Block retest
The last opposite candle before a displacement, retested as demand.
Bullish
Liquidity sweep
Price runs the stops under equal lows, then closes back inside — trapped sellers fuel the move.
Bullish
Fair Value Gap
A three-candle imbalance. Price often returns to rebalance it before continuing.
Bearish
Trendline break
An automatic trendline from swing points, flagged when a candle closes through it.
What a fair value gap is
A fair value gap (FVG) appears when price moves so fast that one candle leaves a gap between the candles on either side of it. Over three candles:
- Bullish FVG: the low of candle 3 is above the high of candle 1. The gap between them is the FVG.
- Bearish FVG: the high of candle 3 is below the low of candle 1.
The idea is that price moved through that zone too quickly for both buyers and sellers to trade fairly, so it often returns to the gap later to rebalance.
How to identify a valid FVG
Gaps appear constantly on low timeframes. Most are noise. The ones traders care about usually have:
- Displacement: the middle candle is large compared with recent candles, showing real urgency.
- A structure break: the move that created the gap also broke a swing high or low. See BOS vs CHoCH.
- Trend alignment: a bullish FVG in an uptrend, a bearish one in a downtrend.
- Freshness: the gap has not been filled yet.
- Meaningful size: the gap is large relative to the coin’s normal range, for example at least a fraction of the ATR.
How to trade an FVG
- Wait for a strong move that breaks structure and leaves an FVG.
- Let price pull back into the gap. Many traders use the middle of the gap (the 50% level) as a reference.
- Look for a reaction inside it, such as a rejection wick or a lower-timeframe shift in structure.
- Place the stop beyond the far side of the gap, or beyond the swing that created it.
- Target the next liquidity pool, such as a recent high.
If price closes cleanly through an FVG in the wrong direction, the gap has failed. Some traders then treat it as an inverse FVG: a failed bullish gap that now acts as resistance.
Which timeframe works best?
Higher-timeframe gaps (1h, 4h, daily) are more significant and fill less predictably, while 1–5 minute gaps are frequent and noisy. A common approach is to find the gap on a higher timeframe and time the entry on a lower one, as described in multi-timeframe analysis.
FVGs with order blocks and liquidity
An FVG next to an order block, created right after a liquidity sweep, is the classic Smart Money Concepts setup: stops taken, then displacement that leaves a gap, then a return to the gap.
Scanning for FVGs
In CryptoScanX, Fair Value Gap is a scan condition, filtered by ATR so tiny gaps don’t count:
Trend-aligned gap
Fair Value Gap = bullish AND Break of Structure = bullish AND Close > EMA(200)
A fresh bullish gap from a structure-breaking move in an uptrend.
Sweep into imbalance
Liquidity Sweep = bullish AND Fair Value Gap = bullish
Stops taken, then displacement that leaves a gap.
Frequently asked questions
What is a fair value gap?
A three-candle price imbalance where the first and third candles do not overlap, leaving a gap. In a bullish FVG, candle 3’s low is above candle 1’s high.
Do fair value gaps always get filled?
No. Many are filled, but strong trends can leave gaps unfilled for a long time. Treat an FVG as an area of interest, not a guaranteed target.
Which fair value gap is valid?
The most useful ones come from a strong, displacing move that also breaks structure, align with the trend, are still unfilled, and are large relative to the coin’s normal range.
What timeframe is best for fair value gaps?
Find gaps on a higher timeframe such as 1h or 4h, then time entries on a lower one such as 5m or 15m.
