CCI COMA

Uses Commodity Channel Index and multi-timeframe moving averages to follow the prevailing trend.

Details

  • Data: Price candles from multiple timeframes.
  • Entry: Long when CCI is above zero, RSI above 50, candle closes above open, and all monitored timeframes show an uptrend; short when opposite.
  • Exit: Position closes on the opposite signal.
  • Instruments: Any instruments.
  • Risk: No explicit stop loss or take profit.
