Overview

GrimmHA Strategy Indicator can show entry signals, trade levels, background colours and a statistics table, with a risk-to-reward ratio and a fixed dollar risk amount as settings. The visible code ends partway through the moving average section, so the exact signal rules are not shown. It draws on the price chart.

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.
