# Post-Trade Risk

> Configure risk thresholds that trigger automatic liquidation and account lockouts

Post-trade risk is evaluated after positions are open. When an account breaches a threshold (like a daily loss limit or trailing max drawdown), the system automatically liquidates positions and can lock the account.

## Configuring Post-Trade Risk Settings

You can configure post-trade risk in two ways:

1. At account creation, by providing a `postTradeRisk` object on the account object.
2. At any time after creation, by calling [`userAccountAutoLiq/update`](/api/rest-api-endpoints/risks/user-account-auto-liq-update).

Both methods let you configure the following settings:

**Note**: All these fields are optional. Omitting a field will simply ignore calculations for that liquidation type. For example, an account without a `dailyLossAutoLiq` has no daily loss limit applied.

| **doNotUnlock**                | When `true`, the account stays locked after a daily loss limit breach instead of auto-unlocking at the next market open. You must manually unlock the account by calling [`setAdminAutoLiqAction`](/api/rest-api-endpoints/risks/set-admin-auto-liq-action) with `adminAction` set to `Normal`.<br /><br />Only affects daily loss limit breaches; standard trailing max drawdown violations lock the account permanently regardless. In a bounced-market scenario where volatility pushes the balance back above the drawdown threshold, `doNotUnlock` keeps the account locked and prevents auto-unlock.<br /><br />There is no bulk endpoint to unlock accounts locked with `doNotUnlock` set to `true`, so accounts must be unlocked one at a time. If you're managing the `doNotUnlock` workflow, plan for a backend process that resets accounts individually before each session. |
