Overview

A bullish gap occurs when the current low is above the high two bars earlier and the middle candle closes above its open. A bearish gap uses the opposite comparison. It draws a solid line at the gap edge and a dashed line at the current extreme, both extending twenty bars forward in green or red. There are no user inputs, alerts, or trade rules. Lines are capped at one hundred.

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
