AK47 A1

Port of the "AK47_A1" MetaTrader expert. The strategy combines Bill Williams' Alligator, DeMarker oscillator, Williams %R filter and fractal triggers to trade breakouts only when the market leaves ranging conditions.

Details

  • Data: Price candles defined by CandleType.
  • Indicators:
    • Alligator jaw/teeth/lips are 13/8/5 period SMMAs shifted by 8/5/3 bars and fed with median price.
    • DeMarker with period 13 must be on the long side of 0.5 for buys and below 0.5 for sells.
    • Williams %R with period 14 is normalized to [0;1]; the previous bar must stay between 0.25 and 0.75 to avoid overbought/oversold states.
    • Fractals are detected from the last 5 highs and lows and remain valid for three bars.
  • Entry Criteria:
    • All three Alligator lines must be separated by at least SpanGatorPoints points (in both bullish and bearish alignment).
    • Long: The most recent lower fractal is fresh, DeMarker ≥ 0.5 and the Williams %R filter approves the trade.
    • Short: The most recent upper fractal is fresh, DeMarker ≤ 0.5 and the Williams %R filter approves the trade.
    • Opposite positions are flattened before opening a new one.
  • Exit Criteria:
    • Hard stop-loss and take-profit defined by StopLossPoints and TakeProfitPoints (converted to absolute prices via the instrument step).
    • Optional trailing stop that trails the close by TrailingStopPoints points once the position moves in favor.
    • When a reverse signal appears the current position is closed before opening the new one.
  • Defaults:
    • SpanGatorPoints = 0.5
    • TakeProfitPoints = 100
    • StopLossPoints = 0 (disabled)
    • TrailingStopPoints = 50
    • CandleType = 1 hour candles
