Overview

Using custom recursive functions, it continuously compares the current bar close against historical state variables to maintain running extreme values. The highest closing price is displayed as a green line, while the lowest closing price is drawn as a red line in a separate indicator pane. It serves as a classic example of tracking persistent extreme levels over time.

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.
