What Is a “Volume-Weighted Average Price” (VWAP) and How Is It Used in Index Calculation?

VWAP is a trading benchmark that represents the average price of an asset over a specified time period, weighted by the volume traded at each price level. In index calculation, using a VWAP from multiple exchanges helps ensure that the final settlement price reflects the true economic value and not just the last traded price on a low-volume venue.

It gives greater importance to prices from exchanges with higher trading activity.
