# Place OSO

POST https://live.tradovateapi.com/v1/order/placeoso
Content-Type: application/json

### Place an Order Sends Order order strategy.

In the Trader application, the details of OSO orders can be viewed by adding the Order Ticket module to your workspace and selecting the Advanced workspace options with Brackets enabled. OSO orders allow for the most complex multi-bracket trading strategies. As an example, imagine MESM1 is trading around 4175.00 points. You want to place a Buy order for 4150.00 points, buying below market. We place an OSO to take profits at 4200.00 points. If the initial order is filled, the `bracket1` order will be sent. Below is an example in JavaScript:

```js
const URL = 'demo.tradovateapi.com/v1'

const oso = {
    action: 'Sell',
    orderType: 'Limit',
    price: 4200.00,
}

const initial = {
    accountSpec: yourUserName,
    accountId: yourAcctId,
    action: "Buy",
    symbol: "MESM1",
    orderQty: 1,
    orderType: "Limit",
    price: 4150.00,
    isAutomated: true //must be true if this isn't an order made directly by a human
    bracket1: oso
}

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

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

> *Note:* If you specify both `bracket1` and `bracket2` the two orders will be linked as an OCO, where filling one will cancel the other.
