Overview
Selective alert() calls marks an upward cross of 50 as a long and a downward cross as a short, using small characters on the oscillator. Alerts fire only for the directions the user enables. By default signals wait until the bar is confirmed, so the live bar does not repaint unless Allow Repainting is turned on. There are no orders, stops, or position sizing.
- 20-period RSI plot
- Long and short cross detection
- Optional confirmed-bar filter

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.
