IU Gap Detector

DISCRIPTION
IU Gap Detector is a smart and flexible gap detection indicator designed to identify Bullish and Bearish price gaps using three different measurement methods: Volatility (ATR), Fixed Points, and Percentage-based gaps.
It helps traders quickly spot significant market gaps that often lead to strong momentum, reversals, or continuation moves.
The indicator works on any timeframe and any tradable instrument supported on TradingView.
