VWMA in Crypto: Why the Value Changes Before Candle Close

A volume-weighted moving average gives heavier bars more influence. On the live bar, both the price and the bar's weight are still changing.

Short answer

VWMA(N) = sum(close × volume) ÷ sum(volume) over N bars. For the live bar, the price is provisional and the volume weight grows through the bar. Early in a bar its weight is small; on a high-volume bar its weight can exceed all others. That means the VWMA can move little at first, then jump late in a heavy bar. Compare VWMA and SMA on the same length to see how much the volume weighting changes intrabar behaviour.

Which part of VWMA uses the live bar

ComponentUses current bar?Effect intrabar
Completed bars (price × volume)NoFixed
Live priceYesMoves
Live volume weightYesGrows through the bar

Two things change at once, so the VWMA's sensitivity to price rises as the bar's volume accumulates.
