At BitMEX, we are committed to continually improving our platform and its infrastructure to support advanced trading capabilities for our users. As part of this ongoing effort, we are announcing an update to our REST and WebSocket APIs.
From 21 October 2025, a new field, strategy, will be added to the BitMEX Order and Execution table/endpoint.
Effective Date and Time: 21 October 2025 at 06:00 – 09:00 UTC
What is changing?
A new field, strategy, will be added to the response of the Order table and Execution table (available via the /order and /execution REST API endpoint and WebSocket API).
For all current orders, this field will be populated with the default value: OneWay.
Please refer to a snippet example in REST API or WebSocket API below:
/order
“account”: 1234567,
“orderID”: “81000000-0000-0000-0000-000000000000”,
“symbol”: “XBTUSDT”,
“strategy”: “OneWay”,
/execution
“account”: 1234567,
“execID”: “2e8f42c4-1b86-291b-c371-87a2c503b1a8”,
“symbol”: “XBTUSDT”,
“strategy”: “OneWay”,
“execType”: “Trade”,
Why are we making this change?
The addition of the strategy field is a necessary preparatory step for upcoming features.
This is an additive change, meaning it introduces a new field without removing any existing data. Most integrations should be unaffected.
