AI Volume Strategy

AI Volume Strategy hunts for sudden participation bursts. A volume spike occurs when current volume exceeds its EMA by a given multiplier. If the spike aligns with the 50-period price EMA and the candle color, the strategy enters in that direction. Each trade is closed after a fixed number of bars.

Details

  • Entry Criteria: Volume > VolumeEMA * VolumeMultiplier and price above/below 50 EMA with matching candle color.
  • Long/Short: Both directions.
  • Exit Criteria: Position closed after ExitBars candles.
  • Stops: None.
  • Default Values:
    • VolumeEmaLength = 20
    • VolumeMultiplier = 2.0
    • ExitBars = 5
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Volume breakout
    • Direction: Both
    • Indicators: EMA, Volume EMA
    • Stops: No
    • Complexity: Basic
    • Timeframe: Any
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
