To add an LME account:
Click +New Account at the top of the Accounts screen.
The Account Information section is displayed.
In the Account Name/Number field when creating an account for LME exchange, enter the up to 40-character exchange-defined account name, which is required for order routing. The user's TT routing account is sent to the exchange as the clearing account on each order action in Tag 58.
Use this field to define the routing behavior for the account and set up its account hierarchy for tiered risk. All order routing is based on user account. Select one of the following:
Routing (external clearing): Defines the parent account as a clearing account sent to the exchange on all orders. If assigned to a user, the account appears in the user's list of routable accounts. When selected by a user, the account is used to route orders and identify the account to the exchange (e.g, FIX Tag 1). If configuring this account as an omnibus account, select this option. If an internal sub-account is assigned to a parent account, the sub-account inherits the exchange connectivity of the parent account.
Note: For exchanges that send the account name as Tag 1, you can override Tag 1 by entering a "Clearing Account Override" located on the account's Exchanges tab.
Routing (internal sub-account): Defines the account as a sub-account that is not routed to the exchange. This allows you to assign the user to an internal account for routing and risk purposes, even though a parent account will be sent to the exchange as the actual clearing or omnibus account.
Tip: Sub-accounts set as "Routing (internal sub-account)" can be selected by client trading applications for submitting orders, but only their parent account is routed to the exchange.
Non-Routing: Not sent to the exchange. Recorded internally and can be used for back-office purposes, or as a parent risk account that allows you to group a set of sub-accounts together and set risk for the non-routing parent.
Tip: Accounts set as "Non-Routing" are not selectable by client trading applications.
Position Transfer — When a match is detected, the resting order is canceled or the working order quantity is reduced by the size of the aggressive order. A fill is created by TT and sent to each account. If the aggressive order was larger than the resting order, then the remainder of it will be sent to market. For a description of how Position Transfer works, refer to Position Transfer.
Position Transfer (if resting order is best bid/offer) — This rule works the same as Position Transfer except that the internal matching occurs only if an order has the potential to fill a resting order at the current best bid/ask price.
Note: When using this rule, the resting order may get matched and filled at the exchange while the aggressive order is in flight.
The new account appears in the Accounts list in the left navigation pane. Sub-accounts appear as nested under their parent account.
