The trading software is designed to facilitate trading and managing multiple
accounts from a single login window. Clients who have their platform
configured for multiple account trading will see each account in the
"Account Information" window:

Each action will be performed on the account which is currently highlighted
(dealing, account history, view reports, etc.) just as if the trader was
managing a single account.
Block trades and orders can also be placed which will automatically be
distributed among the accounts as per the trader's instructions. Indicate
how many lots each account is to receive by clicking on the cell in the "DA"
column ('Default Amount') of the row showing the account details in the
"Account Information" window.
In order to save this information, apply a group name to each row by
left-clicking the appropriate row in the "Group" column. When finished,
save the settings by selecting "File"; "Save Settings" (or “Settings”; “Save
on Server” for ICTS-Wintrader) before you exit.
