Settlement of trades on SSX
In order to maximize the efficiency of trading on SSX and because Australian investors are familiar with existing settlement and transfer processes, SSX uses the services of ASX Settlement to settle trades executed on SSX. ASX Settlement provides a 'delivery versus payment' settlement service and a secure asset holding service. The delivery versus payment (DVP) process allows simultaneous transfer of both securities and money usually two business days after the trade.
