Details on Changes to Websocket Margin and Account Topics

As part of our continuous improvements to the BitMEX platform, on 5 October 2021, we will add the following columns to the margin topic:

  • makerFeeDiscount
  • takerFeeDiscount

These fields exist on the account topic as well, where they will initially remain and be set to null. We will decommission these fields from the account topic at a later date and will not announce it.

This change affects both REST queries and Websocket subscriptions – please update your applications if you currently use these fields. 

These changes will be made in Testnet on 30 September 2021.

Should you have any questions, please contact Support.
