# TWAP Execution Cortex extends TWAP execution to the server side, removing the 12-hour limit and enabling long-duration execution with per-lot monitoring. For an overview of how TWAP works (lot splitting, frequency, jitter, irregular lots, price bounds), see the client-side TWAP documentation. All of those options remain available in Cortex TWAPs. ### Server-Side TWAP Cortex TWAPs execute entirely on the server. There is no upper duration limit, you can run a TWAP spanning minutes, days, weeks, or over a year. The browser does not need to remain open. ### Configuration * **Total Size:** the total order size to execute * **Total Lots:** the number of individual lots to split the order into * **Total Time / End Date:** the duration or target end date for the TWAP * **Slippage:** slippage tolerance for each lot execution All stealth execution options from client-side TWAPs (Frequency Jitter, Irregular Lots, Price bounds) are also supported.

### Per-Lot Execution Each lot within a Cortex TWAP can be individually monitored. Lots can execute using **Chase** and **Swarm** strategies for more sophisticated fill behavior on each individual lot. ### Monitoring Track TWAP progress in real time from the Activity panel on any device: * Overall progress percentage and duration * Average fill price * Total filled vs. target size * Start time and estimated end * Per-lot fill status with individual price, size, and timestamp

TWAP is cancelable at any moment.
