Trend Magic with EMA, SMA, and Auto-Trading Strategy

This strategy uses a CCI-based Trend Magic line together with EMA(45), SMA(90), and SMA(180) filters. A long trade opens when Trend Magic switches to blue during a bullish moving average alignment. Short trades occur when the line turns red and moving averages align bearishly. Each position has a stop at SMA90 and a take profit based on a fixed risk/reward ratio.

Details

  • Entry Criteria:
    • Long: EMA45 > SMA90 > SMA180 and Trend Magic turns blue.
    • Short: EMA45 < SMA90 < SMA180 and Trend Magic turns red.
  • Exits: Stop-loss at SMA90 captured on entry and take-profit at entry ± risk * ratio.
  • Stops: Both stop-loss and take-profit.
  • Default Values:
    • CCI Period = 21
    • ATR Period = 7
    • ATR Multiplier = 1.0
    • Risk Reward = 1.5
