A TWAP strategy is often used to minimize a large order's impact on the market and result in price improvement.^[1] 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. Volume-weighted average price (VWAP) balances execution with volume. Regularly, 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.^[2]

TWAP is calculated using the following formula:

${\displaystyle P_{\mathrm {TWAP} }={\frac {\sum _{j}{P_{j}\cdot T_{j}}}{\sum _{j}{T_{j}}}}\,}$ 

where:

${\displaystyle P_{\mathrm {TWAP} }}$  is Time Weighted Average Price;

${\displaystyle P_{j}}$  is the price of security at a time of measurement${\displaystyle j}$ ;

${\displaystyle T_{j}}$  is change of time since previous price measurement${\displaystyle j}$ ;

${\displaystyle j}$  is each individual measurement that takes place over the defined period of time.

Increased period of measurements ${\displaystyle \sum _{j}{T_{j}}}$  results in a less up-to-date price.
