Trader Services. The stock information is retrieved from the analysis application.
A risk calculation is then performed, and the order is accepted or rejected. If
accepted, the debit of the bank account is performed, then a place order is
performed asynchronously. If the order was placed successfully, a confirmation is
sent to the customer. If the order request was not fulfilled, then a credit (Undo
Debit Account) is executed.
