Multi-Step FlexiSuperTrend Strategy

A SuperTrend filter combined with a smoothed deviation oscillator. The strategy includes three configurable take-profit levels.

Details

  • Entry Criteria:
    • Price below SuperTrend and deviation (SMA of price minus SuperTrend) > 0 → buy.
    • Price above SuperTrend and deviation < 0 → sell.
  • Long/Short: Long, short or both directions.
  • Exit Criteria:
    • Partial take profit at 3 levels.
    • Remaining position closed on trend reversal when price crosses SuperTrend.
  • Stops: No stop logic by default.
  • Default Values:
    • ATR period = 10.
    • ATR factor = 3.0.
    • SMA length = 10.
    • Take profit levels = 2%, 8%, 18%.
    • Take profit percents = 30%, 20%, 15%.
  • Filters:
    • Category: Trend following
    • Direction: Both
    • Indicators: SuperTrend, SMA
    • Stops: Take profit
    • Complexity: Medium
    • Timeframe: Any
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
