Introduction
A Fair Value Gap, commonly called an FVG, is a three-candle price pattern used by some technical traders to study rapid price movement and areas where price did not overlap between the first and third candles.
FVG analysis is associated with certain price-action and Smart Money Concepts trading methods. It is a chart interpretation technique, not proof that institutions have placed orders at a particular price.
Understanding the pattern requires clear rules and an awareness that not every gap produces a profitable trading opportunity.
1. How Is a Fair Value Gap Identified?
A common three-candle definition examines the first candle, the middle candle and the third candle.
For a bullish FVG:
- Identify three consecutive candles.
- The high of the first candle is below the low of the third candle.
- The price interval between those two levels forms the bullish FVG zone.
- The middle candle often shows strong upward movement.
For a bearish FVG:
- Identify three consecutive candles.
- The low of the first candle is above the high of the third candle.
- The interval between those levels forms the bearish FVG zone.
- The middle candle often shows strong downward movement.
The precise rules can vary between indicators and trading systems, so a trader should use one consistent definition when testing results.
2. What Does an FVG Tell a Trader?
Traders use FVGs to identify areas that may be relevant during a future retracement.
For example, after a strong upward move creates a bullish FVG, a trader may watch whether price returns to the zone and then shows evidence of renewed buying pressure.
However, price can continue moving without returning to the zone. It can also enter the zone and continue falling. The presence of an FVG alone is not a buy or sell signal.
3. How Traders Build an FVG Setup
A structured approach may include:
Market context: Determine whether the broader price structure supports the trade direction.
Zone identification: Apply a consistent three-candle FVG definition.
Entry condition: Define what must happen before entering, such as a retracement plus a separate confirmation rule.
Invalidation: Determine the price level at which the trade idea is considered invalid.
Position sizing: Calculate a position size that respects the predefined monetary risk.
Exit plan: Set the target using tested strategy rules and account for costs.
These conditions should be written down before historical testing rather than adjusted after seeing the outcome.
4. Common FVG Trading Mistakes
Trading every FVG: A chart may contain many zones that do not fit the trader's strategy.
Ignoring market context: A pattern should be evaluated alongside trend, structure, volatility and relevant price levels.
Assuming every gap fills: Markets do not have to revisit every identified zone.
Using inconsistent definitions: Changing candle rules or timeframes can make backtest results difficult to compare.
Ignoring spread and slippage: Small targets may be heavily affected by trading costs.
5. How to Test an FVG Strategy
Record the instrument, timeframe, zone definition, entry rule, stop-loss, target and outcome for each historical trade.
Use enough historical data to include different market conditions. Keep a separate sample for validation instead of judging a strategy only on the data used to create it.
Measure win rate, average win, average loss, maximum drawdown and net performance after estimated costs. Then test in a demo account before considering live execution.
Conclusion
Fair Value Gaps provide a repeatable way to describe certain three-candle price patterns. Their usefulness depends on the rules surrounding them and whether those rules demonstrate an advantage under realistic testing.
An FVG is a potential area of interest, not a guarantee of a price reversal or institutional activity.
