Notice
ASX participants and users are advised that ASX will be making changes to market maker quoting obligations, covering minimum quote size obligations and allocations within quoting schedules, in a range of Single Stock ETO Classes. The changes have been made based on consultation with Market Makers, accounting for market changes over the past 12 months.
ASX has a general policy in setting the level of ETO Special Size (with respect to number of contracts) to 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 17 November 2025.
A summary of the 13 ETO Classes whereby minimum quoting size and corresponding Special Size level are changing can be found below:
