The Australian exchange has selected Nasdaq to deliver its "next generation post-trade risk management solution".
"Sentinel Risk Manager will provide a single, real-time risk management system across both ASX clearing houses and all asset classes, including real-time margin calculation and related customer risk analytics," said a joint statement by Nasdaq and the ASX.
The ASX's new 'technology transformation', announced to the market in February 2015, will be rolled out in five phases over the next two years.
ASX chief information officer Tim Thurman said that consolidating the ASX's risk technology onto Sentinel's real time technology will "enable ASX to more efficiently fulfill global risk management best practices and provide risk capital benefits to customers".
"The opportunity to deliver both a cross-margining simulation and optimisation service will add significant value to our clearing participants and their clients," Mr Thurman said.
Nasdaq has provided technology to the ASX since 1996.
