Renko Live Charts Pimped Strategy

This strategy builds renko bricks and trades on direction changes. It can optionally calculate the brick size from ATR values, allowing the renko structure to adapt to market volatility.

Details

  • Entry Criteria:
    • Long: bullish renko brick after a bearish brick.
    • Short: bearish renko brick after a bullish brick.
  • Long/Short: Both.
  • Exit Criteria:
    • Reverse signal.
  • Stops: No.
  • Default Values:
    • BoxSize = 10m.
    • Volume = 1m.
    • CalculateBestBoxSize = false.
    • AtrPeriod = 24.
    • AtrCandleType = 60m.
    • UseAtrMa = true.
    • AtrMaPeriod = 120.
  • Filters:
    • Category: Trend Following
    • Direction: Both
    • Indicators: Renko, ATR
    • Stops: No
    • Complexity: Intermediate
    • Timeframe: Renko
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
