TWAP

From Wikipedia, the free encyclopedia

TWAP is a trading acronym for Time Weighted Average Price. See also VWAP.

TWAP is the average price of contracts or shares over a specified time.

TWAP underpins more sophisticated ways of buying and selling than simply executing orders en masse: for example, dumping a huge number of shares in one block is likely to affect market perceptions, with an adverse effect on the price. High-volume traders use TWAP to execute their orders over a specific time so they trade to keep the price close to that which reflects the true market price. TWAP orders are a strategy of executing trades evenly over a specified time period. VWAP balances execution with volume. Often, a VWAP trade will buy or sell 40% of a trade in the first half of the day and then the other 60% in the second half of the day. A TWAP trade would most likely execute an even 50/50 volume in the first and second half of the day.
