SFE Gateway Documentation

Additional Considerations


This section includes additional information related to Order and Fill Server behavior.

Verifying Order Sessions

You can verify the connectivity status of each order session using the View Status option in Guardian by logging in as an Administrator. Each order session appears in Guardian as a separate Order Router. The session name appears as Router with a Guardian-assigned number at the end (e.g., Router1). GatewayCompany (FIX Tag 49 SenderCompID) and the GatewaySessionID (FIX Tag 50 SenderSubID) information appear under the status column.

Omnibus Account and FFT3

SFE Gateways allow orders to be submitted with omnibus accounts. If you choose to use an omnibus account, you must provide the omnibus account number in the FFT3 field of X_TRADER®s Customer Defaults. The SFE Gateway forwards the omnibus account number to the exchange as if the omnibus account was entered in the Account field of the order. This allows the user to use their normal Account field for internal identification purposes.

Additionally, for all order confirmations and fills, the SFE Gateway displays the omnibus account number in X_TRADER®s FFT3 field and provides the trader’s original account number in the Account field. FFT3 is mapped to FIX Tag 1.

FFT2 Field

The FFT2 field in the Customer Defaults section in X_TRADER® will populate FIX Tag 448 in the TT SFE Gateway. If FFT2 is populated, then Tag 452 is set to "24".  In X_TRADER®, the contents of the FFT2 field can be changed within the Fill window after a trade occurs.

As the ASX have removed post trade amendment, you can no longer update the FFT2 reference on any filled order on SFE Gateway 7.18. You can, however, still update the FFT2 reference on any working orders, including the remaining working portion of a partially filled order.

The exchange imposes a 6 character limit for the FFT2 field.

For more information on the FFT2 field, refer to the Customer Defaults Setup section in the X_TRADER® User Manual.

Exchange Throttle

Each FIX Order Entry session is throttled to 15 TPS. The throttle is based on a rolling one second with buffering on additional orders above the TPS. You can increase the throttle per FIX Order Entry ID in 15 TPS increments up to 75 TPS. Contact ASX directly for any questions.

Unintentional Crossing Prevention

SFE Gateway 7.18.14 or higher supports the exchange's Unintentional Crossing Prevention (UCP) functionality. To support this in your trading environment, enter your UCP ID (crossing key)  in the "Exchange 1" field in the User's Gateway Login Attributes section of TT User Setup. The Order Server will populate the UPC ID on all order messages sent to the exchange.
