ColorMaRsi Trigger Strategy

This strategy is a StockSharp port of the original MQL5 expert exp_colormarsi-trigger.mq5. It compares fast and slow EMAs and fast and slow RSI values. The combined signal takes values -1, 0 or +1. A position is opened when the previous signal has the opposite sign to the current one.

How it works

  • When the signal turns from positive to zero or negative, a long position is opened and any short position is closed.
  • When the signal turns from negative to zero or positive, a short position is opened and any long position is closed.

Parameters

  • Fast EMA – period for the fast exponential moving average.
  • Slow EMA – period for the slow exponential moving average.
  • Fast RSI – period for the fast RSI.
  • Slow RSI – period for the slow RSI.
  • Candle Type – timeframe of the candles used for calculation.

Indicators

  • Exponential Moving Average (fast and slow)
  • Relative Strength Index (fast and slow)

Only finished candles are processed. Orders are placed using BuyMarket and SellMarket.
