# Trim or close an options or stock trade

`POST https://app.skylit.ai/api/nexus/v1/trades/{id}/exits`

API: Nexus.

Sell part of a trade with `quantity`, or all of what's left with `"closeAll": true`. Not both. Fills at market (the live bid for options), or at your own `price` inside the window, as on an open.

On a test order's id this is a test exit, whatever the body says. Futures have no exits: close a futures position with the account close route.

## Authentication

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

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `id` | path | string (uuid) | yes | The trade's id, from the open or the list. |
| `Idempotency-Key` | header | string | no | Your `clientOrderId`, as a header instead of a body field. If you send both they must match. |
