Event: Balance and Position Update

Event Description​

Event type is ACCOUNT_UPDATE.

• When balance or position get updated, this event will be pushed.

  • ACCOUNT_UPDATE will be pushed only when update happens on user's account, including changes on balances, positions, or margin type.
  • Unfilled orders or cancelled orders will not make the event ACCOUNT_UPDATE pushed, since there's no change on positions.
  • "position" in ACCOUNT_UPDATE: Only symbols of changed positions will be pushed.

• When "FUNDING FEE" changes to the user's balance, the event will be pushed with the brief message:

  • When "FUNDING FEE" occurs in a crossed position, ACCOUNT_UPDATE will be pushed with only the balance B(including the "FUNDING FEE" asset only), without any position P message.
  • When "FUNDING FEE" occurs in an isolated position, ACCOUNT_UPDATE will be pushed with only the balance B(including the "FUNDING FEE" asset only) and the relative position message P( including the isolated position on which the "FUNDING FEE" occurs only, without any other position message).
