Mean Reversion Pro Strategy

Mean Reversion Pro is a mean reversion system built for major indices. It uses two moving averages and intrabar range levels to detect pullbacks. Long trades are preferred as indices tend to move upward.

Details

  • Entry Criteria:
    • Long: Close below fast SMA, close below 20% range level, close above slow SMA, no position.
    • Short: Close above fast SMA, close above 80% range level, close below slow SMA, no position.
  • Long/Short: Both (long recommended).
  • Exit Criteria:
    • Long: Close crosses above fast SMA.
    • Short: Close crosses below fast SMA.
  • Stops: None.
  • Default Values:
    • Fast SMA = 5
    • Slow SMA = 100
    • Direction = Long only
  • Filters:
    • Category: Mean reversion
    • Direction: Configurable
    • Indicators: SMA
    • Stops: None
    • Complexity: Simple
    • Timeframe: Daily
