Renko Trend Reversal Strategy

Renko Trend Reversal Strategy trades when renko open crosses renko close. Stop-loss and take-profit can be enabled. Uses ATR-based renko bricks.

Details

  • Entry Criteria: renko open/close cross with time window
  • Long/Short: Both
  • Exit Criteria: optional stop loss or take profit
  • Stops: Optional
  • Default Values:
    • RenkoAtrLength = 10
    • StopLossPct = 10
    • TakeProfitPct = 50
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: ATR
    • Stops: Optional
    • Complexity: Basic
    • Timeframe: Renko
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
