Boilerplate Configurable Strategy

The Boilerplate Configurable strategy can switch between two modes: a simple moving average crossover or a Bollinger squeeze breakout. It features trading day and session filters, a date range, a news window, and risk management using ATR or static risk/reward.

Details

  • Entry Criteria:
    • In SmaCross mode, go long when the fast SMA crosses above the slow SMA and go short on the opposite cross.
    • In Squeeze mode, enter when price breaks the outer Bollinger band while remaining inside the narrower band.
  • Long/Short: Configurable for long, short, or both with optional inversion.
  • Exit Criteria:
    • Stop loss and take profit based on ATR or static percentages.
    • Daily exit period and news window close all positions.
  • Stops: Per-trade stop loss and take profit with drawdown protection.
  • Default Values:
    • Length = 20
    • WideMultiplier = 1.5
    • NarrowMultiplier = 2
    • MaxLossPerc = 0.02
    • AtrMultiplier = 1.5
    • StaticRr = 2
    • NewsWindow = 5
    • MaxDrawdown = 0.1
  • Filters:
    • Category: Modular
    • Direction: Long & Short
    • Indicators: SMA, Bollinger Bands, ATR
    • Stops: Yes
    • Complexity: High
    • Timeframe: Any
    • Seasonality: Yes
    • Neural networks: No
    • Divergence: No
    • Risk level: High
