Trader and Firm Identification

Obtaining Exchange Credentials/Membership


Before trading at SGX, individuals must obtain a SGX Membership. SGX offers four membership categories:

    • Clearing Member
    • Trading Member
    • Trading Member (Proprietary)
    • Trading Member (Individual)

For further details, please refer to the following link:


TT Direct Trader IDs


You can determine and set up any Member ID, Group ID, and Trader ID you like.


You must complete the following fields in Guardian to map a TTORD proxy trader to a direct trader:

    • Exchange: The TT Gateway exchange-flavor (e.g., SGX-A).
    • Member: Identifies the client’s Member login.
    • Group: A three-digit variable defined by the firm.
    • Trader: A multi-digit variable defined by the firm.

TTORD Trader IDs


The following lists how SGX_OTC Gateways use TTORD trader IDs.

    • SGX_OTC Gateways support TTORDs.
    • You can map multiple TTORDs to one direct exchange trader.

Each TTORD ID used to connect to and trade on the Exchange must use a unique clearing account.


FFT2 and FFT3 Fields


By default, SGX_OTC Gateways use the FFT2 field to populate the customer_info_s API field. For Give Up orders, it is mapped to ex_customer_s.

SGX_OTC Gateways  do not use the FFT2 field to populate the ex_client_s API field. FFT3 can be used for routing omnibus account numbers. If populated, FFT3 is mapped to the ex_client_s API field.



Account Field


SGX Gateways use the Account field in X_TRADER® to populate the ex_client_s API field.


The SGX Risk Controls interface will reject any order submitted with lowercase values in the ex_client_s field. Therefore, users must populate the Account field in X_TRADER with uppercase values unless they are using Omnibus account handling.

  Use FFT3 to send an Omnibus account number to the exchange. If FFT3 is populated, the Account field is not sent to the exchange.
