Overview
Alertcondition() on Single Condition monitors for centerline crossings, displaying upward green triangles at the bottom when RSI crosses above 50 and downward red triangles at the top when RSI crosses below 50. Built as a demonstration of alert functionality, it registers alertcondition calls for both events. It contains no adjustable user inputs or automated trade execution logic.
- 20-period RSI calculation
- Midline crossover and crossunder detection

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.
