IU Range Trading Strategy

The IU Range Trading Strategy identifies consolidation zones where the price range over a lookback period stays within an ATR multiplier. Breakout trades trigger when price exceeds the range boundaries. Positions are protected by an ATR-based trailing stop that moves with favorable price action.

Details

  • Entry Criteria: Price breaks above or below a narrow ATR-defined range.
  • Long/Short: Both directions.
  • Exit Criteria: ATR-based trailing stop.
  • Stops: Yes.
  • Default Values:
    • RangeLength = 10
    • AtrLength = 14
    • AtrTargetFactor = 2.0m
    • AtrRangeFactor = 1.75m
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Breakout
    • Direction: Both
    • Indicators: ATR, Highest, Lowest
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: Intraday
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
