Inverse Fair Value Gap (IFVG) definition
A fair value gap that price closed decisively through, flipping it into a level that now supports the opposite direction.
This page is the short definition. For rules, worked NQ examples and invalidation, read the full Inverse Fair Value Gap guide.
What it means in ICT
ICT reads a failed FVG as a change of intent: the gap that should have held becomes resistance in a bearish flip, or support in a bullish one.
NQ example
When a bullish NQ FVG fails and price closes below it in the NY AM Killzone, the first retest of that gap from underneath is the bearish IFVG short.

Data & methodology
All NQ and MNQ examples use Databento GLBX.MDP3 1-minute OHLCV candles for continuous front-month E-mini Nasdaq-100 futures, aggregated to higher timeframes (5m, 15m, 1h, 4h, 1D, 1W) so every bar agrees across timeframes. Sessions cover the full CME Globex day, 18:00–17:00 ET. ICT overlays are drawn algorithmically from the same price data used in the replay trainer.
