Overview

By default, it detects when price crosses above a ten-period simple moving average and records price changes, peak high, and minimum low values over a user-defined lookback window. The script stores these metrics in arrays to calculate average statistical performance and plots average change, maximum potential gain, and minimum potential drawdown in a separate indicator pane. Traders can adjust the evaluation window setting to examine historical post-event movements.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
