Simple Fair Value Gap (FVG) Detector – Code Snippet

Hello everyone, I want to share a simple but effective code snippet I use to detect Fair Value Gaps (FVG). It highlights both Bullish (green) and Bearish (red) imbalances based on a standard 3-candle pattern. You can easily integrate this logic into your own strategies as a trend or entry filter. Here is the code:

// --- FAIR VALUE GAP (FVG) DETECTION ---


MinGap = 2 * pipsize 


// 1. Bullish FVG
BullishFVG = (Low > High[2]) AND (Low - High[2] >= MinGap)


// 2. Bearish FVG
BearishFVG = (High < Low[2]) AND (Low[2] - High >= MinGap)


// --- VISUAL REPRESENTATION ---
IF BullishFVG THEN
   DrawRectangle(barindex[2], High[2], barindex, Low) coloured(0,255,0,50) bordercolor(0,255,0,0) 
ENDIF


IF BearishFVG THEN
   DrawRectangle(barindex[2], Low[2], barindex, High) coloured(255,0,0,50) bordercolor(255,0,0,0) 
ENDIF


RETURN

This is the core mathematical logic I use to filter imbalances in my automated systems.
