# Event: Balance and Position Update

## Event Description[​](https://developers.binance.com/docs/derivatives/usds-margined-futures/user-data-streams/Event-Balance-and-Position-Update)

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).
-   The field "m" represents the reason type for the event and may shows the following possible types:
    
    -   DEPOSIT
    -   WITHDRAW
    -   ORDER
    -   FUNDING\_FEE
