ASX participants and users are advised that ASX will be making changes to the market maker quoting obligations in a range of Single Stock ETO Classes. ASX will be making changes to the minimum quote size obligations, allocation of quoting schedule and the quoting schedule itself.
ASX has a general policy in setting the level of ETO Special Size (with respect to number of contracts) to a 15 times multiple of the minimum market maker quote size. As such, Special Size levels and associated Equity FlexClear™ entry size levels will be adjusted accordingly.
The changes to market maker quoting obligations and Special Size levels of affected ETO Classes will become effective from Monday 3 April 2023.
