ADX System

The ADX System strategy trades using the Average Directional Index and its DI components. It opens a position when the ADX rises and one of the directional lines crosses above the ADX. Positions include fixed take-profit and stop-loss levels with a trailing stop to protect profit.

Details

  • Entry Criteria
    • ADX is rising (previous ADX below current).
    • For long trades: previous +DI below previous ADX and current +DI above current ADX.
    • For short trades: previous -DI below previous ADX and current -DI above current ADX.
  • Exit Criteria
    • Opposite signal on ADX and DI lines.
    • Price reaches the trailing stop level.
    • Price hits the fixed take-profit or stop-loss.
  • Long/Short: Both directions.
  • Stops: Fixed stop-loss, take-profit, and trailing stop in absolute price units.
  • Default Values:
    • AdxPeriod = 14
    • TakeProfit = 15
    • StopLoss = 100
    • TrailingStop = 20
    • CandleType = TimeSpan.FromMinutes(5)
  • Filters:
    • Category: Trend-following
    • Direction: Both
    • Indicators: ADX, +DI, -DI
    • Stops: Yes
    • Complexity: Beginner
    • Timeframe: Short-term
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
