Color Step Xccx Strategy

Strategy based on the Color Step XCCX indicator. The indicator measures the deviation of price from a smoothed average and plots two step lines. A long trade is opened when the fast line falls below the slow line. A short trade is opened when the fast line rises above the slow line.

Details

  • Entry Criteria:
    • Long: fast line crosses below slow line
    • Short: fast line crosses above slow line
  • Long/Short: Both
  • Exit Criteria:
    • Long: fast line crosses above slow line
    • Short: fast line crosses below slow line
  • Stops: None
  • Default Values:
    • DPeriod = 30
    • MPeriod = 7
    • StepSizeFast = 5
    • StepSizeSlow = 30
    • CandleType = TimeSpan.FromHours(4).TimeFrame()
  • Filters:
    • Category: Trend

    • Stops: No
    • Complexity: Intermediate
    • Timeframe: Medium-term
