ColorMaRsi Trigger MMRec Duplex Strategy

Overview

This strategy is a StockSharp high level API port of the MetaTrader expert Exp_ColorMaRsi-Trigger_MMRec_Duplex.mq5. It runs two independent MaRsi-Trigger blocks – one for long opportunities and another for short opportunities. Each block evaluates a composite signal generated by comparing a fast and a slow moving average together with a fast and a slow RSI. The composite valu e is clamped to the range [-1, 1], reproducing the behaviour of the original indicator: +1 marks bullish alignment, -1 mar ks bearish alignment, and 0 indicates mixed conditions.

A money-management “MMRec” module monitors the latest trades for each direction. When a configurable number of losses appears wit hin a moving window, the next trade switches to a reduced volume until performance recovers. This reproduces the adaptive positio n sizing logic of the MetaTrader library TradeAlgorithms.mqh used by the expert.

Trading Logic

  1. Indicator pipeline (per block):

    • Compute a fast moving average (MA_fast) and a slow moving average (MA_slow) on the selected applied price and timeframe.
    • Compute a fast RSI (RSI_fast) and a slow RSI (RSI_slow) on possibly different applied prices.
    • Build a color score: start at 0, add +1 if MA_fast > MA_slow or -1 otherwise, then add +1 if RSI_fast > RSI_slow or -1 otherwise. Clamp the result to [-1, 1].
    • Store the score history and read it with the configured SignalBar shift (the default matches the MetaTrader implementation).

  2. Long block:

    • Entry: allowed when no long position is open (shorts are covered first). The previous colour (SignalBar + 1) must be + 1 while the current colour (SignalBar) is ≤ 0, indicating the bullish block has just neutralised.
    • Exit: when the previous colour turns negative (-1) and exits are enabled.

  3. Short block:

    • Entry: allowed when no short position is open (longs are closed first). The previous colour must be -1 while the curren t colour is ≥ 0, signalling a fresh bearish-to-neutral transition.
    • Exit: when the previous colour turns positive and exits are enabled.

  4. Stops and targets: optional stop-loss and take-profit distances are expressed in price steps and re-evaluated on every fini shed candle. Crossing either boundary closes the respective position immediately.

  5. Money management: the strategy stores the result of each completed trade (per direction) and counts the number of losses in the latest HistoryDepth trades. If the loss count reaches LossTrigger, the next order uses the reduced volume. Otherwise, the normal volume is used.

Notes

  • Applied price options follow MetaTrader semantics. For example, Weighted equals (High + Low + 2 * Close) / 4 and Typical e quals (High + Low + Close) / 3.
  • When the long and short blocks share the same timeframe (default), a single candle subscription feeds both calculators.
  • Setting the loss trigger to 0 forces the reduced volume immediately, mirroring the behaviour of the original money management helper.
  • The strategy uses market orders; the MetaTrader Deviation parameter is therefore not required.
