# Cancel everything resting, or one contract's orders

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

API: Nexus.

`"cancelAll": true` cancels every resting order on the account. `ticker` cancels only that contract's. Not both. Nothing resting answers `200` with `meta.nothingToCancel: true`.

If one cancel fails part way, the error says how many were cancelled and which order is still working. Read the working list and send the cancel again. With `"test": true` it cancels the account's test orders in your test log and never touches a real order.

## 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. |

### 200

What was cancelled. `meta.count` is how many.

One limit order cancelled.:

Only the NQ orders: an entry and its held stop go together, so one cancel took both.:
