XAUUSD Simple 20 Profit 100 Loss Strategy

This strategy opens a long position when no position is held and both cooldown timers are inactive. It closes the position once unrealized profit reaches $20 or the loss hits $100. After a profitable exit the strategy waits 15 minutes before re-entering, and after a losing exit it waits 12 hours.

Parameters

  • ProfitTarget – profit target in USD.
  • LossLimit – maximum loss in USD.
  • TradeCooldown – time to wait after a loss.
  • EntryCooldown – time to wait after a profit.
  • CandleType – candle timeframe.
