Trading Hours Survey - Responses and Outcome

d-cyphaTrade and the ASX have undertaken an extensive survey of market participants regarding trading hour preferences. d-cyphaTrade and the ASX would like to thank the market for the significant response. We have received feedback from a large number of market participants and as a result we will be making some changes to the on-screen trading hours of the market.

A. On-screen Trading Hours - NEW TRADING HOURS 9:00 - 16:00 (Sydney time)

Although there was a degree of support for keeping the hours as they are currently, the majority of support was for shortening the hours to a 9:00 - 16:00 (Sydney time) on-screen trading day.

B. Time of SFE Daily Settlement Price Determination (DSPD)

It was generally felt that the DSP should be determined at the close of the on-screen market i.e. 16:00 (Sydney time).

C. Block Trade Trading Hours

There was no clear consensus for block trading hours with the feedback evenly split and as such there will be no change to the current hours of 9:00 - 17:00 (Sydney time).

These changes will take effect from and including Thursday the 5th of November 2009.
