# Move a resting order's price

`POST https://app.skylit.ai/api/nexus/v1/trading/accounts/{account}/orders/{orderId}/modify`

API: Nexus.

Moves a working limit or stop order (or a bracket's stop or target) to a new `price`, like dragging it on the Nexus chart. Only the price can change. To change the size, cancel the order and place a new one.

No live price answers `503 no_live_price` and the order stays where it was. A test order can't be moved (`400 test_modify_unavailable`): cancel it and send a new test order at the new price.

## Authentication

Send your Skylit API key as a bearer token: `Authorization: Bearer <key>`. No other header is accepted.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `account` | path | string | yes | `practice`, `evaluation` or `funded` (when you have exactly one running), or a futures account id from capabilities. |
| `orderId` | path | string (uuid) | yes | The order's id, from the open, the working list or the history. |
