# Modify Order Strategy

POST https://demo.tradovateapi.com/v1/orderStrategy/modifyorderstrategy
Content-Type: application/json

### Modify a running Order Strategy.

**Available to:** All authenticated users

**Environments:** Demo, Live

**[Rate Limit](/api/authentication#request-rate-limits-and-time-penalties):** 500 requests per hour, 2-second back-off, counts all requests

Sends a `command` to an Order Strategy that is already running, identified by its `orderStrategyId`. Order strategies are the multi-bracket constructs created with [`startOrderStrategy`](/api/rest-api-endpoints/orders/start-order-strategy); this endpoint adjusts one of those strategies after it is live without tearing it down and rebuilding it. To stop a strategy entirely, use [`interruptOrderStrategy`](/api/rest-api-endpoints/orders/interrupt-order-strategy) instead.

The request body requires `orderStrategyId` and a `command` string (up to 1024 characters) describing the change to apply. The optional `customTag50` carries a registered tag; if your account requires tag50 registration, an unregistered tag is rejected before the command runs.

As with other order commands, success is not guaranteed — the underlying orders may already have filled, the strategy may have completed, or the exchange may reject the change. The endpoint returns an `OrderStrategyStatusResponse`. When the request is rejected, the response carries a `failureReason` and an `errorText` describing the problem; on success the response includes the updated `orderStrategy`.

**Common Failure Scenarios**

- The strategy or its orders already completed or were cancelled (`TooLate`).
- Another command for the strategy is still being processed (`AnotherCommandPending`).
- The user isn't permitted to trade this account (`Unauthorized`).
- A required `customTag50` is missing or unregistered.

**Error Messages**

| `failureReason` | Trigger |
|-----------------|---------|
| `TooLate` | The strategy or its orders already completed or were cancelled. |
| `AnotherCommandPending` | A previous command for this strategy hasn't completed. |
| `Unauthorized` | The user isn't permitted to trade this account. |

See the `failureReason` enum in the `OrderStrategyStatusResponse` schema for the complete list of values.
