Overview
When a crossover occurs, it triggers an alert condition, executes a dynamic alert call with the current close price, and plots a value of 1 (and 0 otherwise) in a separate pane. It also tests Pine Script v6 logging functions by outputting info, warning, and error messages on the last confirmed historical bar. The script has no user-configurable inputs.

Risk Notes
No repainting, lookahead or stacked entries were found in its code or README. That says nothing about how well it works: test it first.
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.
