Parabolic SAR with MACD Confirmation

This strategy combines the Parabolic SAR indicator with MACD confirmation. A position is opened when price crosses the SAR in a direction supported by MACD, aiming to capture trend reversals.

Details

  • Entry Criteria: Price crosses SAR and MACD line is on the same side of its signal line.
  • Long/Short: Both directions.
  • Exit Criteria: Opposite crossover of price/SAR or MACD.
  • Stops: No.
  • Default Values:
    • SarStart = 0.02m
    • SarIncrement = 0.02m
    • SarMax = 0.2m
    • MacdFast = 12
    • MacdSlow = 26
    • MacdSignal = 9
    • CandleType = TimeSpan.FromMinutes(5)
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: Parabolic SAR, MACD
    • Stops: No
    • Complexity: Intermediate
    • Timeframe: Intraday
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
