A volume moving average (volume MA) is a rolling average of bar-level volume over a window — typically 20 or 50 bars. It is the cleanest way to define 'high volume' versus 'low volume' for a given asset and timeframe without picking an arbitrary absolute threshold.
Trading reads: a breakout on volume above 1.5× or 2× the volume MA is treated as confirmed participation, while a breakout on below-average volume is often considered suspect. Volume MAs are also used as a filter — only act on signals when current volume exceeds the average.
Volume MAs are normally computed as a simple moving average, since the goal is a stable baseline rather than fast responsiveness. They are calibrated per-asset because volume scales vary wildly across instruments.
Formula
VolMA_t = (V_t + V_{t-1} + ... + V_{t-N+1}) / NEsempio
20-bar volume MA on BTC = 1,200 contracts. Current bar volume = 2,800 — about 2.3× the average, qualifying as a volume-confirmed bar.
