VWAP in Crypto: Why the Value Changes Before Candle Close

VWAP is cumulative from its anchor, so every new trade on the live bar changes it. Early in a session it moves a lot; late in a session, very little.

Short answer

VWAP = Σ(typical price × volume) ÷ Σ volume since the anchor (e.g. 00:00 UTC). The live bar's volume and price are added continuously, so VWAP changes intrabar. Its sensitivity falls as the session accumulates volume: one hour in, a heavy bar can move VWAP noticeably; twenty hours in, the same bar barely moves it. Price crossing VWAP intrabar is common near the line; judge reclaims and losses on closed bars.
