Ha MaZi

Combines Heikin Ashi candles, an EMA filter, and ZigZag pivot confirmation. A long trade is opened when a bullish Heikin Ashi candle forms at a new ZigZag low above the EMA. Shorts appear on a bearish candle at a new ZigZag high below the EMA. Positions are closed by fixed stop loss or take profit.

Details

  • Long/Short: Both directions.
  • Exit Criteria: Stop loss or take profit.
  • Stops: Fixed stop and target.
  • Default Values:
    • MaPeriod = 40
    • ZigzagLength = 13
    • StopLoss = 70
    • TakeProfit = 200
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: Heikin Ashi, EMA, ZigZag
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: Intraday
    • Seasonality: No
