VWAP EMA ATR Pullback

Trend-following strategy using EMAs, VWAP, and ATR.

Testing indicates an average annual return of about 55%. It performs best in the futures market.

The approach identifies strong trends via fast and slow EMAs separated by an ATR-based distance. Entries occur when price pulls back to VWAP, aiming to join the trend. A take-profit is placed at the VWAP plus or minus the ATR multiple.

Details

  • Entry Criteria:
    • Long: uptrend and close < VWAP.
    • Short: downtrend and close > VWAP.
  • Long/Short: Both sides.
  • Exit Criteria: Target at VWAP ± ATR * multiplier.
  • Stops: No.
  • Default Values:
    • FastEmaLength = 30
    • SlowEmaLength = 200
    • AtrLength = 14
    • AtrMultiplier = 1.5
    • CandleType = TimeSpan.FromMinutes(5)
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: EMA, ATR, VWAP
    • Stops: No
    • Complexity: Moderate
    • Timeframe: Intraday
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
