You submit a spread order the same way you submit an order for an exchange-traded instrument. For example, you can submit the spread order in an MD Trader® widget by specifying the quantity and clicking a price level, as shown. In this example, the spread is configured to submit quoting orders for both legs.
You can also use supported TT Algos, such as TT Iceberg, to manage an Autospreader order. Simply select the desired TT Algo from the order type drop-down.
The Autospreader MD Trader spread panel provides you with the ability to select separate accounts for routing the child orders of a parent spread order. For example, you can use separate accounts on different exchanges to submit orders for cross-exchange spreads, or split trading between separate accounts and different brokers.
When you launch a spread, the legs are seeded automatically based on any order default account settings you may have configured. The default accounts may also be different per leg.
To submit an Autospreader order using multiple accounts:
Click the account selector in the MD Trader spread panel and select Multi....
In the flyout panel that appears, click the account selector for each leg and select an account.
Your default account displayed in All Legs is used for routing the leg orders.
When you select a different account for each leg, then Multi... appears in All Legs and each separate account is displayed for Leg 1 and Leg 2, etc.
Configure and submit the spread order in the MD Trader spread pane.
After submitting the order, the flyout panel closes and the spread, quoting, and hedge orders are submitted into the market. The leg orders are routed using the different accounts you selected.
If you hover on the account selector in the MD Trader spread panel, a tooltip appears and displays your account selections for each leg.
Using the Floating Order Book, you can delete a parent spread order and leave the child order(s) working in the market. For more details about how to abandon Autospreader child orders, refer to Deleting parent orders in the Floating Order Book.
