Fair Value Gap
By LuxAlgoJul 28, 2023
Fair Value Gap is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
Fair Value Gap finds the voids that aggressive moves leave behind and manages their whole life cycle on the chart. A bullish gap prints when the current low clears the high from two bars back; a bearish gap when the current high stays under the low from two bars back. Each imbalance becomes a box, and the box is deleted once a bar closes back through it, the foundational detection pattern behind the Smart Money Concepts family.
How to Trade the Fair Value Gap?
- Fresh gap prints: one-sided pressure just left a range untraded. Treat the box as a zone of interest where price may return before continuing.
- Price closes through a box: once a bar closes beyond the gap's far edge, the gap is mitigated and removed; enable Mitigation Levels to leave dashed lines at those prices for later retests.
- Higher-timeframe confluence: run the Timeframe input above the chart (for example 1-hour gaps over a 15-minute chart) and favor setups that align across both.
- Dashboard read: bullish and bearish gap counts with mitigation percentages show how reliably the market has been filling its inefficiencies lately.
Fair Value Gap Settings
- Threshold %: the minimum size a gap must reach to count, with Auto deriving the threshold from average volatility instead.
- Unmitigated Levels: how many of the most recent open gaps stay highlighted.
- Mitigation Levels: draws dashed lines where gaps were filled.
- Timeframe: runs detection on a timeframe independent of the chart.
- Extend / Dynamic: projects boxes forward and lets subsequent price action resize their boundaries; further toggles cover dashboard visibility, corner, and text size.
