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 and allocations within quoting schedules.

The changes are being made based on market condition changes and market maker feedback.

ASX has a general policy in setting the ETO Special Size level (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 on Monday 3 June 2024.

A summary of the 14 ETO Classes whereby minimum Quote Size and corresponding Special Size level are changing can be found below:
