Overview
Placeholder buy and sell conditions track an open long or short state and can fire entry alerts immediately or only after a bar closes. It calculates optional stop-loss and take-profit prices from a fixed shift, a percentage, pips, ATR, or recent candle extremes, and it also supports trailing and breakeven adjustments. Settings change the maximum position count and whether debug stop levels are shown. No real entry logic is filled in.
- End-of-turn alert option
- Multiple stop-loss calculation types
- Trailing stop and breakeven levels
- Multiple take-profit calculation types
- Maximum position count
