Fellow Binancians,

We are excited to announce “TRADE_LITE”, a new feature being added to the USDⓈ-M Futures Websocket, will be launched on 2024-09-03 (UTC). “TRADE_LITE” is designed to reduce user data latency by focusing solely on ‘TRADE’ execution type and minimizing the number of user data fields, providing a faster and more efficient experience compared to the original "ORDER_TRADE_UPDATE" user data stream.

Scheduled Upgrade for USDⓈ-M Futures Websocket: 

To support the launch of the TRADE_LITE feature, the USDⓈ-M Futures Websocket will undergo a scheduled upgrade at 2024-09-03 06:00 (UTC). The upgrade is expected to take approximately 4 hours.

During the upgrade period, users may experience intermittent disconnections in their Futures Websocket (fstream) User Data Streams. If a disconnection occurs, users can re-establish connection to the Futures Websocket (fstream) server.

After the upgrade is complete, users can subscribe to TRADE_LITE to experience a more streamlined and faster user data push.
