Universum 3.0 Strategy

DeMarker oscillator based strategy that opens positions on each completed bar and adjusts volume using a martingale scheme.

Details

  • Entry Criteria:
    • Long: DeMarker > 0.5
    • Short: DeMarker < 0.5
  • Long/Short: Both
  • Exit Criteria:
    • Positions are closed by take profit or stop loss
  • Stops: Absolute points via TakeProfitPoints and StopLossPoints
  • Default Values:
    • DemarkerPeriod = 10
    • TakeProfitPoints = 50m
    • StopLossPoints = 50m
    • InitialVolume = 1m
    • LossesLimit = 100
    • CandleType = TimeSpan.FromMinutes(1).TimeFrame()
  • Filters:
    • Category: Trend following
    • Direction: Long & Short
    • Indicators: DeMarker
    • Stops: Yes
    • Complexity: Low
    • Timeframe: Short-term
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: High
