How VWAP works
VWAP, or volume-weighted average price, is the average price of an asset over a period weighted by how much traded at each price. Because heavier volume counts for more, VWAP shows the price level where most business actually happened, not just the midpoint of the range. Institutions use it as a fairness benchmark: filling below VWAP on a buy is a good execution, above it is a poor one.
Worked example
A stock trades between $99 and $101 all day, but most of the volume goes through near $100.20 during a busy afternoon. The simple average might be $100.00, but the VWAP is $100.20, because it weights toward where the real volume was. A trader told to buy at or below VWAP must fill under $100.20 to beat the benchmark, regardless of the headline range.
VWAP as a trading reference
Traders also read VWAP as an intraday line: price above it suggests buyers are in control, below it suggests sellers, and big players try to fill against it to prove good execution. On Volity, VWAP helps you judge whether your entry is rich or cheap relative to where the day’s volume cleared, and complements TWAP for working larger orders.
Why it matters
VWAP is the institutional standard for measuring execution quality, so understanding it helps you time entries near fair value instead of chasing extremes. Use it as a reference line, not a signal on its own. Related: volume and TWAP.
