# Event: Risk level change

## Event Description[​](https://developers.binance.com/docs/derivatives/options-trading/user-data-streams/Event-Risk-level-change)

-   Updates whenever there is an account risk level change. The following are possibly values:
    -   NORMAL
    -   REDUCE\_ONLY
-   Note: Risk level changes are only applicable to VIP and Market Makers user accounts.
