SGX_OTC Gateway Documentation

TT Gateway and the Exchange

Exchange Background

The Singapore Exchange Limited is Asia Pacific’s first demutualised and integrated securities and derivatives exchange. SGX was formed on December 1st, 1999, with the merger of Stock Exchange of Singapore (SES) and the Singapore International Monetary Exchange (SIMEX). In November of 2000, SGX was the first Asian Pacific exchange to be listed via a public offer and private placement.

SGX offers access via QUEST, an electronic trading platform. Access is given through exchange-approved Order Management Systems developed by either exchange members or Independent Software Vendors. For reporting wholesale trades, SGX offers the Titan OTC interface, which uses the Transport Layer Security (TLS) protocol to connect to the interface and provide a secure connection between the SGX_OTC Gateway and the exchange.


You can find the preceding exchange information on SGX’s website.

Time and Time Zone

Set the machine that hosts the SGX_OTC Gateway to run in (GMT+8:00) Singapore Standard Time zone and time. You must turn-off the Automatically adjust clock for daylight saving changes setting.


Ensure the time zone is set correctly. Failure to do so will result in an incorrect fill transaction time.

Required Connection Information

Users must work with the exchange to acquire the following connection information:

  • User IDs

Exchange API Interface

For reporting OTC trades, SGX uses the Titan OTC FIX API interface for connectivity.


The SGX matching engine is located in Singapore.

Prices at SGX are determined through Price/Time Priority. Alternatively, prices may also be determined using alternative algorithms: Price Point Maker (PPM), Market Maker (MM), and Pro-Rata Order and Matching.


Pro-Rata Order and Matching only applies to EY products.
