What Is the Significance of the Volume-Weighted Average Price (VWAP) in Measuring Execution Quality?
VWAP is the average price of an asset traded over a specific time, weighted by the volume traded at each price level. It is a key benchmark for measuring the quality of a trade's execution.
If a trader's execution price is better than the VWAP, they achieved a good price relative to the market's average, indicating a narrow effective spread. If it is worse, the effective spread was likely wide.
