Hi Mat, The order book is set up in the morning with the two types of market makers. These reference prices are used by all other venues. Including after Mifid 2, the Lse's new parallel book, darkpools etc. The reason that the retail orders are not filled at that price is because they may not be routed to that venue, for price improvement & cost savings for the Broker. Interestingly on the Carillian board, posters could not understand why some sales just prior to the delisting were honoured & some not. They wrongly assumed that all orders went to the Lse & were covered by the Lse rules. This level of detail is vital to Pro traders but PI's prefer not to know & think it not relevant, as they are long term investing.
