OK I will try and explain how a trade executes on STSqx
1, Investor asks broker for a price to trade sell or Buy
2, Broker scans the MMs( effectively banks that are registered with LSE) and gets the best quote available. There are circa 8 MMs
3,MM returns with a price, by regulation it has to be within the MMs advertised spread if the quantity requested does not breach the block size, 75K shares for HE1
4, Your broker relays the price offered by the MM to you and starts the 15 second timer for your confirmation.
5, If the trade is taken the MM reports the trade to LSE
6, Up to now there is no 'exchange trade' no price matching or no order book you have simply traded shares like you would a car to a car dealer.
7, If you don't want to trade immediately and want to place an order, you order goes to your broker and sits there until the condition for the order is met
8, for a period of about 10 mins and six times a day there is an 'auction' where investors can trade shares without using a broker or a MM and trade 'On exchange' directly with another investor. most people do not have access to the auction
9, The auction is separate and not related to the trading that goes on all day via the broker /MM route
