What is a fair value gap?
A fair value gap (FVG) is an imbalance between three consecutive candles: there is a "void" between the high of the first candle and the low of the third (or vice versa). That void represents a fast, inefficient move that the market tends to come back and "fill".
How to identify it
Look for a large, impulsive middle candle. If the shadow of the previous candle does not overlap the shadow of the next candle, there is an FVG between them.
How to trade it in binary options
When price returns to the FVG, it tends to react. Use the FVG as an entry zone in the direction of the main trend, confirming with the nearest order block.
⚠️ Caution
Not every FVG is filled immediately. Use it as a zone of interest, not an automatic entry trigger.
