DCASS stands for Derivatives Clearing And Settlement System and serves as a single clearing and settlement system
for both the HKFE Clearing Corporation Limited (HKCC) and The SEHK Options Clearing House Limited (SEOCH). 
DCASS was launched in April 2004 and was upgraded to the Genium INET Platform in October 2013.

DCASS shares the same platform and infrastructure as the derivatives trading system, HKATS.  HKATS and DCASS
form the integrated trading and clearing system for HKEX’s Derivatives Markets.

DCASS is a fully electronic and automated clearing and settlement system that comprises the core derivatives clearing
and settlement functionality, the margining engine, and has the capability to support various types of derivatives
products such as Equities, Currencies and Commodities.

Clearing Participants can access DCASS through a terminal which provides easy access to DCASS and is designed
to support Clearing Participants as it facilitates manual input of post-trade activities.

Moreover, Clearing Participants with high clearing volume can consider accessing DCASS through the OMnet
Application Programme Interface which facilitates straight through processing and enhances operational efficiency.
