# Place OCO

POST https://demo.tradovateapi.com/v1/order/placeoco
Content-Type: application/json

### Place a Order Cancels Order order strategy.

OCO order strategies link 2 orders together such that if one order is filled, the other order is cancelled. You must provide an `other` parameter pertaining to the order linked to this one. The `other` must specify an `action` and an `orderType` which determines the other parameters that must be set. For example a Limit or Stop order must use the `price` parameter, but a Stop-Limit will require a `price` and a `stopPrice`. Below is an example of an OCO that either sells to take profit at 4200 points, or sells to stop loss at 4100 points.

```js
const URL = 'demo.tradovateapi.com/v1'
const limit = {
    action: 'Sell',
    orderType: 'Limit',
    price: 4200.00
}
const oco = {
    accountSpec: yourUserName,
    accountId: yourAcctId,
    action: "Buy",
    symbol: "MESM1",
    orderQty: 1,
    orderType: "Stop",
    price: 4100.00
    isAutomated: true, //must be true if this isn't an order made directly by a human
    other: limit
}

const response = await fetch(URL + '/order/placeoco', {
    method: 'POST',
    headers: {
        'Accept': 'application/json',
        'Authorization': `Bearer ${myAccessToken}`,
    },
    body: JSON.stringify(oco)
})

const json = await response.json() // { orderId: 0000000, ocoId: 0000000 }
```
