1 The Exchange determines those trading segments in which trading is supported by market makers, and may admit one or more market makers for each security, as set out in Clause 5.
2 The market maker undertakes to ensure a liquid market for the securities in question by performing the following functions for a given period within trading hours:
providing bid and ask prices;
offering minimum bid and ask volumes; and
not exceeding a maximum bid-ask spread.
3 Only participants that have entered into a market maker agreement are subject to market making provisions.
