Exp ADX Cross Hull Style Strategy

This strategy combines Average Directional Index (ADX) cross signals with a Hull Moving Average (HMA) filter. Entries occur when the +DI line crosses above the -DI line for longs or below for shorts. Exits are handled by a pair of Hull moving averages: the fast average crossing the slow average closes positions. The strategy operates on the 4-hour timeframe by default.

Details

  • Entry Criteria
    • Long: +DI crosses above -DI.
    • Short: -DI crosses above +DI.
  • Exit Criteria
    • Long: fast HMA falls below slow HMA.
    • Short: fast HMA rises above slow HMA.
  • Indicators
    • AverageDirectionalIndex (period 14).
    • HullMovingAverage fast length 20.
    • HullMovingAverage slow length 50.
  • Timeframe: 4-hour candles (configurable).
  • Stops: none by default.
  • Direction: both long and short.

The strategy does not rely on historical collections; it reacts to streaming candle data. Parameters can be optimized for different markets. Chart output displays price candles with both Hull moving averages and trade marks.
