Heiken Ashi Waves Strategy

Strategy blending Heikin-Ashi candles with a dual moving average wave filter. The fast SMA (2) crossing the slow SMA (30) signals potential wave changes and is confirmed by the current Heikin-Ashi candle direction.

Details

  • Entry Criteria:
    • Long: bullish Heikin-Ashi candle and fast SMA crossing above slow SMA
    • Short: bearish Heikin-Ashi candle and fast SMA crossing below slow SMA
  • Long/Short: Both
  • Exit Criteria:
    • Opposite cross
    • Trailing stop loss
  • Stops: Trailing stop in points via StopLoss
  • Default Values:
    • FastLength = 2
    • SlowLength = 30
    • StopLoss = new Unit(20, UnitTypes.Point)
    • UseTrailing = true
    • CandleType = TimeSpan.FromHours(1).TimeFrame()
  • Filters:
    • Category: Trend Following
    • Direction: Both
    • Indicators: Heikin Ashi, SMA
    • Stops: Yes
    • Complexity: Beginner
    • Timeframe: Intraday
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
