Account Code Mapping

Description

For MX, all submitted orders must contain an account type that is mapped to an exchange account code. The account type entered in X_TRADER® for an order action is mapped to an account code that is sent to MX. The exchange rejects any order submitted without an account code.

In addition, you may use any TT account type except G1, G2, and G3. The MX Gateway rejects any order submitted with an invalid account type. The mapping of account types to account codes is not configurable on the MX Gateway.

Account Numbers

Warning

User account numbers must not exceed twelve (12) characters in length. If their account numbers exceed the twelve-character limit, the MX Gateway will reject their orders.

MX restricts account numbers to a maximum length of twelve characters. For account numbers less than twelve characters, the gateway pads the account number field with additional spaces and sends the account number to the exchange.
