Delete User Account Risk Parameter

### Delete a risk parameter from a position limit. **Available to:** All authenticated users **Environments:** Demo, Live **[Rate Limit](/api/authentication#request-rate-limits-and-time-penalties):** No endpoint-specific limit Removes the `UserAccountRiskParameter` identified by `userAccountRiskParameterId`, the single required field in the request body. A risk parameter is a child constraint of a `UserAccountPositionLimit`, so deleting it removes one pre-trade rule while leaving the parent position limit and its other parameters in place. To remove the entire position limit instead, use [`deleteUserAccountPositionLimit`](/api/rest-api-endpoints/risks/delete-user-account-position-limit). To find the `userAccountRiskParameterId` to delete, list the parameters of a position limit with [`userAccountRiskParameter/deps`](/api/rest-api-endpoints/risks/user-account-risk-parameter-dependents). The endpoint returns a `DeleteResultResponse` with a `success` boolean and an `errorText` field that is non-empty only when the request fails. A failed deletion does not change the account's risk configuration. **Common Failure Scenarios** - `userAccountRiskParameterId` is missing. - The referenced risk parameter does not exist or is not visible to the calling user. **Error Messages** | `errorText` | Trigger | |-------------|---------| | Non-empty `errorText` | The request failed; the field describes the reason. |
