 Archer On-Balance Volume (AOBV) applies dual exponential smoothing to the classic On-Balance Volume indicator, creating a responsive yet noise-filtered momentum signal. The intersection of fast and slow EMAs provides actionable crossover signals while preserving OBV's core insight: volume precedes price.
 
 Developed by EverGet (known as "Archer" in the TradingView community), AOBV addresses OBV's fundamental weakness—its sensitivity to single high-volume bars that can distort the cumulative reading. By smoothing with EMAs of period 4 (fast) and 14 (slow), AOBV filters noise while maintaining responsiveness to genuine accumulation/distribution shifts.
