Moving Average Crossover Swing Strategy

Trades when a fast exponential moving average crosses a medium one with optional confirmation from a slow MA and MACD histogram. Uses ATR-based stop loss and take profit and can exit on a secondary MA cross.

Details

  • Entry Criteria:
    • Fast EMA crosses above medium EMA for long, below for short.
    • Optional: price above/below slow EMA.
    • Optional: MACD histogram above/below zero.
  • Long/Short: Configurable.
  • Exit Criteria: ATR-based stop loss and take profit or optional exit MA cross.
  • Stops: Yes, ATR multiples.
  • Default Values:
    • FastPeriod = 5
    • MediumPeriod = 10
    • SlowPeriod = 50
    • FastExitPeriod = 5
    • MediumExitPeriod = 10
    • AtrPeriod = 14
    • AtrStopMultiplier = 1.4
    • AtrTakeMultiplier = 3.2
    • EnableSlow = true
    • EnableMacd = true
    • EnableLong = true
    • EnableShort = false
    • EnableCrossExit = true
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Trend following
    • Direction: Configurable
    • Indicators: EMA, MACD, ATR
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: 1m (default)
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
