FVG: What a Fair Value Gap Is and Why You Need It

FVG (fair value gap) is a specific kind of imbalance framed into a clear three-candle model. The concept is popular in modern price action and helps you precisely mark zones price tends to return to. Let's break down what an FVG is, how to mark it, and why you need it in analysis.

What an FVG is

An FVG is an area of imbalance, a 'gap' on the chart that price left during a fast impulsive move and that's considered a zone of unfair (inefficient) price due to be filled. In essence, an FVG is a formalized imbalance: the same logic of an under-traded zone passed through too quickly, but expressed through a clear, easily marked model of three candles. The name reflects the idea: the market left a zone where price was 'unfair,' and it strives to return to restore fairness (efficiency) of trading.

The three-candle model

An FVG is marked by three consecutive candles. In a bullish impulse, the FVG is the gap between the high of the first candle and the low of the third: if there's an unclosed zone between them (the low of the third candle above the high of the first), that zone is the FVG, the area the middle candle's impulse shot through without trading. A bearish FVG is the mirror: the gap between the low of the first candle and the high of the third in a downward impulse. The middle candle is that same strong impulse that created the gap. This formalization makes marking an imbalance unambiguous and repeatable.

Why you need an FVG

An FVG is needed as a precisely marked zone of likely price reaction. Like any imbalance, an FVG acts as a magnet: price often returns to it to fill the gap and continues the move from there. This gives the trader a concrete area to look for an entry with the trend (a return to the FVG in the impulse's direction, a fill, a continuation) and a clear target for pullbacks. The advantage of the FVG over an abstract imbalance is its clarity: the three-candle model gives unambiguous zone boundaries, which simplifies marking, setting the entry, and the stop (beyond the FVG).

How to use it and caveats

An FVG is applied together with structure and trend, not as a standalone signal. A return to a bullish FVG in an uptrend is an area to look for a buy on confirmation; to a bearish FVG in a downtrend, for a sell. The entry is made on price reaction in the zone (bounce confirmation), the stop beyond the FVG boundary, the target in the trend's direction. The caveats matter: filling an FVG is a tendency, not a guarantee (price may not return, may fill partially, or may pass straight through), FVGs on higher timeframes and in the trend's direction are more significant, and on forex marking goes by price. The FVG is a popular but not a magic tool: it precisely marks an imbalance zone, but it doesn't remove the need for confirmation and work with structure.

Practical takeaway

FVG (fair value gap) is a formalized kind of imbalance, a three-candle model marking a 'gap of fair price': in a bullish impulse, the zone between the high of the first candle and the low of the third; in a bearish one, the mirror. Like any imbalance, an FVG acts as a magnet: price tends to return to fill the gap and continue the move, giving a precise area for a trend entry and a target for pullbacks. The FVG's advantage is clarity of marking: unambiguous boundaries simplify the entry and stop placement (beyond the zone boundary). Use the FVG together with structure and trend: a return to the zone in the impulse's direction is an area to look for an entry on confirmation. Remember that filling is a tendency, not a guarantee, higher-timeframe FVGs and those with the trend are more significant, and marking on forex goes by price. Understanding the FVG gives a clear, precisely marked tool for working with imbalance, helping you find zones of likely reaction and entry points with the trend, but not replacing confirmation and structure analysis.
