Charles 1.3.7 Strategy

This strategy places symmetric stop orders above and below the current price and uses trailing exits to capture breakouts.

Parameters

  • Anchor – distance in price steps to place stop orders.
  • XFactor – multiplier for the order volume.
  • Trailing Stop – trailing stop distance in price steps.
  • Trailing Profit – profit threshold to exit the position.
  • Stop Loss – fixed stop loss in price steps (0 disables it).
  • Volume – base order volume.
  • Candle Type – timeframe of processed candles.

Trading Logic

  1. When no position is open, cancel existing orders and place both a Buy Stop and Sell Stop at Anchor steps from the last candle close.
  2. When a position is opened, the opposite stop order is cancelled. The entry price is remembered for exit calculations.
  3. For a long position, if profit reaches Trailing Profit or the price falls by Stop Loss, the position is closed. For a short position, the logic is mirrored.

The strategy is designed as an example of breakout trading with simple risk management.
