MLTrendE Strategy

This strategy trades in the direction of a weighted moving average (WMA) and optionally pyramids positions when price moves favorably.

Logic

  • Calculate a WMA of the selected candle series.
  • If no position is open:
    • Trade type 0: open a long position when the close price is above the WMA, or a short position when it is below.
    • Trade type 1: always open a long position.
    • Trade type 2: always open a short position.
  • When a position is open and reaches the specified profit target, add another trade with scaled volume.
  • Once the maximum number of trades is reached, the entire position is closed at the next profit target.

Parameters

  • Volume – base trade volume.
  • Multiplier1 – volume multiplier for the second trade.
  • Multiplier2 – volume multiplier for the third trade.
  • TakeProfit – profit in price units required to scale or close.
  • Map – period of the weighted moving average.
  • MaxTrades – maximum number of consecutive trades.
  • TradeType – 0 trend following, 1 force long, 2 force short.
  • CandleType – timeframe of the analyzed candles.

Notes

The strategy uses only completed candles and market orders. It does not manage stops or risk; use account protection if needed.
