Fair Value Gaps Explained: How to Trade FVGs and Measure Them Honestly
A fair value gap (FVG) is one of the most searched chart concepts in modern price-action trading, and one of the most loosely used. The idea is simple; the edge, if you have one, lives in the details. Here is what an FVG actually is, how traders commonly trade it, and the part most guides skip: how to measure whether it works for you.
What a fair value gap is
A fair value gap is a three-candle pattern where the middle candle moves so fast that it leaves an unfilled zone between its neighbours: the wicks of candle one and candle three do not overlap. That untraded zone is the gap. The reading is that price moved with such imbalance (one-sided buying or selling) that the market may later return to trade through the prices it skipped.
| Direction | How it forms | The gap zone |
|---|---|---|
| Bullish FVG | A strong up candle in the middle of three. | Between candle one's high and candle three's low. |
| Bearish FVG | A strong down candle in the middle of three. | Between candle one's low and candle three's high. |
How traders commonly trade FVGs
- Retracement entry: wait for price to trade back into the gap, then look for entries in the direction of the original move.
- Midpoint focus: many traders treat the middle of the gap (sometimes called consequent encroachment) as the decision level rather than the full fill.
- Confluence, not isolation: an FVG aligned with the higher-timeframe trend, a session open, or a key level is a different trade from a random gap on a quiet chart.
- Invalidation: if price trades cleanly through the whole gap and keeps going, the imbalance story is done and the setup is off.
Why FVGs alone are not an edge
Every fast move leaves gaps, so charts are full of them. In trending conditions gaps often act as continuation zones; in ranging conditions many simply fill and reverse. Session matters too: an FVG printed during a liquid London or New York session tells you more than one from a thin holiday market. In other words, the pattern is a lens, not a system. Whether it makes you money depends on your filters, your risk, and your discipline, which is exactly why it has to be measured.
Measure the setup like a professional
Treat FVG trading as a hypothesis. Tag every FVG trade in your journal, attach the chart screenshot showing the gap, and note the context: timeframe, session, with or against the higher-timeframe trend. After 30 to 50 tagged trades, read the numbers: win rate, average win versus loss, and expectancy, all net of fees. That is the difference between trading a concept you saw online and trading a setup you have verified on your own account.
TradePulse makes that loop automatic: your trades sync from cTrader or MetaTrader 5 with exact prices and fees, you add the FVG tag and screenshot in seconds, and your win rate, profit factor and expectancy are computed for you, broken down by session. The journal does not detect FVGs for you; it does something more useful, it tells you honestly whether yours work.
Create your free TradePulse account (no card needed) and journal up to 50 trades, or start the 7-day Pro free trial. cTrader auto-sync works from day one of the trial; MetaTrader 5 auto-sync activates with your first Pro payment. Cancel before the trial ends and you pay nothing.
FAQ
Do all fair value gaps get filled?
No. Many gaps fill partially or never fill at all, especially in strong trends. Treating 'price always returns to the gap' as a rule is one of the fastest ways to donate money to the market.
What timeframe is best for FVGs?
There is no universally best timeframe. Higher timeframes produce fewer, more significant gaps; lower timeframes produce many more, with more noise. Pick one context, trade it consistently, and judge it on a real sample of your own trades.
Does TradePulse detect FVGs automatically?
No, and we are honest about that. TradePulse is a journal: it imports your trades automatically, lets you tag FVG setups and attach the chart screenshot, and then shows you the setup's real win rate, profit factor and expectancy, net of fees.
