Prev Candle Before Biggest Body (3-7am EST)

This indicator automatically identifies and marks, for each trading day, the candle immediately preceding the largest open-to-close movement (in pips) during the key London session window from 3:00am to 7:00am EST (New York time). The largest candle is determined by the absolute difference between its open and close prices, measured in pips. The candle just before this “biggest” move is highlighted with a distinctive pink flag above the bar. This tool is especially useful for traders seeking to analyze pre-breakout price action or to identify key levels and setups that occur right before significant volatility during the early London session.
