# Open a Limit or Stop Order

> Open non-market trigger orders on Ostium with the Builder SDK.

Use `OrderType.Limit` or `OrderType.Stop`.

```ts theme={null}
await client.openTrade({
  pairId: 0,
  buy: true,
  price: '64000',
  collateral: '100',
  leverage: '5',
  type: OrderType.Limit,
});
```

## Important behavior

* `price` is the trigger price
* slippage is ignored for non-market orders
* use `getOpenOrders()` to inspect active limit orders later
