Fair Value Gap (FVG) Trading Strategy — How to Trade Imbalances

The fair value gap (FVG) is one of the core concepts in ICT-style trading. It marks a spot where price moved so quickly that one side of the market barely traded — an imbalance. Those areas often act as magnets or turning points when price returns.

For the broader framework this fits into, read the ICT trading strategy guide first.

How to identify a fair value gap

Look at any three consecutive 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.

Candle 2 is usually a large, strong-bodied candle — the displacement move.

Which gaps are worth trading

Most charts are full of small gaps. Only a few matter:

1. Created by displacement. The middle candle should be noticeably larger than recent candles.
2. After a liquidity sweep. The strongest FVGs form right after price takes out an obvious high or low and reverses.
3. Breaking structure. The displacement move should break a recent swing point.
4. Aligned with the higher timeframe. A bullish 5-minute FVG inside a bullish 1-hour trend is far better than one fighting it.
5. Unmitigated. The first return to the gap is the one to trade.

The trading rules

Bullish example (mirror for bearish):

1. Identify the 1-hour bias — higher highs and higher lows.
2. On the 5-minute chart, wait for price to sweep a sell-side level such as the prior session low.
3. Wait for a bullish displacement candle that breaks the most recent swing high and leaves a bullish FVG.
4. Entry: limit order at the top of the FVG, or at its midpoint (the “consequent encroachment”) for a better price and lower fill rate.
5. Stop: below the swing low that formed the sweep.
6. Target: the nearest buy-side liquidity — a prior high or equal highs — then the next higher-timeframe level.

A worked example on EUR/USD

The 1-hour trend is up. During the London open, EUR/USD sweeps the Asian low at 1.0840 by 5 pips to 1.0835, then a strong 5-minute candle breaks the last swing high at 1.0852.

• Candle 1 high: 1.0846. Candle 3 low: 1.0851. The bullish FVG is 1.0846–1.0851, with its midpoint at 1.08485.
• Entry: a limit at the top of the gap, 1.0851.
• Stop: 2 pips below the sweep low, 1.0833 — 18 pips of risk.
• Target: equal highs at 1.0887 — 36 pips, exactly 2R.

Entering at the midpoint instead (1.08485) cuts the risk to 15.5 pips and lifts the reward to 38.5 pips — about 2.5R — but price may not reach it.

Timing

FVG setups have the best follow-through during the London and New York sessions — the ICT “killzones.” Gaps that form in the quiet Asian afternoon or US lunch hour are lower quality.

Risk management

FVG entries often come with tight stops, which makes over-sizing tempting. Fix your risk per trade first and calculate size with the position size calculator for forex, or the futures calculator for ES and NQ.

Rule of thumb. If you can’t point to the liquidity that was taken before the gap formed, skip it. Gaps without a sweep are the ones that fail most often.

Common mistakes

• Trading every gap. Without the sweep and structure break, an FVG is just a fast candle.
• Ignoring the higher timeframe. Counter-trend gaps fill and then keep going against you.
• Moving the stop into the gap. If price trades through the whole FVG and your invalidation level, the idea is wrong.
• No time filter. Session timing matters as much as the pattern.

Managing the trade

• Partial at 1R and move the stop to breakeven.
• Hold the runner to the liquidity target — the reason the trade exists.
• Exit on a close back below the gap (for longs): if price closes through the entire FVG, the imbalance has been absorbed.

How to backtest FVGs

Mark 50 or more setups with screenshots and tag each one: sweep present or not, session, higher-timeframe alignment, entry type (top of gap vs. midpoint). Comparing results by tag shows which filters actually add edge in your market. A trading journal makes the tagging easy.

Frequently asked questions

What is a fair value gap in trading?

A fair value gap is a three-candle pattern where the wick of the first candle and the wick of the third candle do not overlap, leaving a price area that the middle candle moved through quickly. ICT traders treat it as an imbalance that price often revisits.

Do all fair value gaps get filled?

No. Many gaps are only partly filled, and gaps in a strong trend may never be revisited. Treat an FVG as a zone of interest, not a guarantee.

What timeframe is best for fair value gaps?

Many traders find gaps on the 5-minute or 15-minute chart for entries and confirm direction on the 1-hour or 4-hour chart. Gaps on very low timeframes are frequent but less reliable.

Should I enter at the top of the gap or the midpoint?

Entering at the top of the gap fills more often; entering at the midpoint (consequent encroachment) gives a better price and a better reward-to-risk but misses trades that never retrace that far. Track both in your journal.

What is an inverse fair value gap?

An inverse FVG is a gap that price closes through in the opposite direction. ICT traders then watch it as a zone where the role has flipped — former support acting as resistance, or vice versa.
