The exchange is an over all name for the trading I used, If you look on Exchange website they do not post buy/sell but just the trade. Bottom line is the trades have no signal attached, no matter whom you offer up as the reporter of said trades. Obligations for whom reports it is here nor there... It is simply a trade at a price, albeit sell for one buy for another. Depends who you are as to which it is for you. But on LSE website it is a binary decision on L2 positions and mid point.
If you watch enough RSP you can see the MMs play all sorts of games. If a MM had a lot of stock to sell below ASK. Why would they move a BID up to give impression they were looking to buy, but not actually bid for any shares to buy above that raised BID?.... Because they have plenty to sell obviously, but this is signalling to market there has been buying interest such that bid is raised to create liquidity to service the buying..... That they are in fact actually desperate for.
Then there is 1 on Bid, 5 on ASK, with no shares available to buy RSP quote, then 5 on Bid and 1 on ASK but lots available to buy. In the second case many L2 watchers be going, heavily bid and only 1 MM on ask, when in fact the RSP ask is stuffed with shares to sell. Contradicting the L2 positions. Im sure they know that's how lots perceive the L2 picture.
Oh and they like to iceberg their intentions too, 150k that gets taken 10 times for example, yet they'll complain when you break an order down.
