FVG/IFVG Detector Pro

FVG Detector Pro – with Automatic IFVG
Description

FVG Detector Pro is an advanced indicator designed to automatically detect Fair Value Gaps (FVG) and Inverse Fair Value Gaps (IFVG).

It helps traders visualize market imbalances created by impulsive price movements and quickly identify when a Fair Value Gap fails and becomes an inverse reaction zone.

This tool is built for intraday and futures trading (NQ, MNQ, ES, etc.) and works on any timeframe.

What is a Fair Value Gap (FVG)?

A Fair Value Gap represents a price imbalance where the market moved too quickly and did not trade efficiently.

Detection rules used:

Bullish FVG: Low > High[2]

Bearish FVG: High < Low[2]

FVGs often act as:

retracement zones

reaction areas

continuation or rejection zones

IFVG – Inverse Fair Value Gap

An IFVG is created when a Fair Value Gap is invalidated by price action.

Invalidation rules:

Bullish FVG becomes Bearish IFVG when price closes below the FVG bottom

Bearish FVG becomes Bullish IFVG when price closes above the FVG top

This indicates that the original imbalance failed and the zone now acts in the opposite direction.

How to Use the Indicator
Standard FVG Setup

A Fair Value Gap is created

Price retraces into the zone

Price reacts in the direction of the FVG

IFVG Setup (High-Probability Scenario)

A Fair Value Gap is formed

Price fails and breaks through the zone

The zone converts into an IFVG

A retest of the IFVG often provides an entry in the opposite direction

IFVGs frequently represent failed expectations and can offer strong trading opportunities.

Recommended Timeframes

1m / 2m / 5m for scalping and intraday trading

15m / 30m for higher-timeframe context

The indicator is fully timeframe-independent.

Best Practices

Always use FVGs and IFVGs with market context (VWAP, session levels, trend bias)

IFVGs are especially effective around the US session open

Avoid trading FVGs directly against strong momentum
