# Dry Run

POST https://live.tradovateapi.com/v1/order/dryrun
Content-Type: application/json

### Validate an order without placing it.

**Available to:** All authenticated users

**Environments:** Demo, Live

**[Rate Limit](/overview/core-concepts/rate-limits):** 500 requests per hour, 1-second back-off, counts all requests

Submit one or more orders (up to four) for validation against the account's pre-trade risk settings without actually placing them. The response includes a `rejectReason` if the batch would be rejected, so you can surface issues to the trader before they submit a real order.

Use this to check whether an order would pass margin requirements, position limits, and other risk checks before committing to a live trade.

The optional `extraPreTradeRisk` field lets you apply additional risk constraints beyond the account's default settings during validation.

**Common Failure Scenarios**

- The account does not exist (returns `HTTP 404`)
- The caller doesn't have access to the account (returns `HTTP 401`)
- The request contains more than four orders
- Invalid `contractId` in one or more orders
