What it means
VWAP is the average price weighted by volume over a specified period — typically the current trading session. Calculated as: cumulative (price × volume) / cumulative volume from session start. Resets at session boundaries (typically session open). Critical for institutional execution: most institutional orders are measured against VWAP as the execution benchmark. 'Better than VWAP' = good execution; 'worse than VWAP' = poor execution.
Why it matters
VWAP is the single most important price level for institutional traders. Large desks execute orders aiming to beat VWAP; this creates real flow gravity around VWAP itself. Price above VWAP = institutional buyers struggling to fill at favorable prices; price below VWAP = institutional sellers struggling. The level acts as dynamic support/resistance especially in liquid futures and stocks.
How to use it
Track session VWAP intraday. Use as dynamic support/resistance: long bias when price holds above VWAP, short bias when below. VWAP touches in trending direction often provide entry pullbacks. Anchored VWAP (from a specific event) is a powerful variant — calculated from a notable event (earnings release, IPO, swing low) rather than session open.
NVDA session VWAP at $135 with stock trading $137. Pullback to $135.50 found buyers, bounced to $138 by end of session. VWAP acted as institutional buy-the-dip level. Classic intraday support/resistance dynamic.
