Why MaC?

Currently, about 25% of all trading in South Africa is conducted in
closing auctions (approximately R1.3 trillion annually). The MaC
offers a cost effective alternative to transact in the closing auction
and find additional liquidity.

What MaC offers?

MaC allows Members to enter orders for matching on A2X at the official closing price of the market-of-listing end-of-day auction. It is an innovative order type that is designed to bring competition into the closing auctions and give the industry a genuine choice.

How it Works

MaC Orders are accepted throughout the trading day. At 3/4 of the way through the market of listing Auction A2X will commence its randomised lock phase, which may last up to 30 seconds, and match Orders on its auction book, not allowing any new Orders, amendments, or cancellations. Upon lock, unmatched Orders will be cancelled back to the submitting Member

01

MaC unlocked phase

Starts at the same time as the market of listing auction. Market orders may be entered amended or cancelled.

02

MaC random lock period

The MaC lock period starts mid-way through the market of listing auction, at a random point during a 30 second window.

03

MaC locked phase

After the random lock the MaC order book is locked from any member changes. Orders are matched with member and time priority. Any unmatched orders are cancelled, allowing members enough time for those orders to be sent elsewhere.

04

MaC execution

The MaC execution confirmation follows completion of the MoL auction. The orders that were matched are executed at the MoL closing price and execution is disseminated in the market data.
