On Friday i thought it was odd that i could get a quote for nearly 59000 shares. I have now discovered that Nova has been moved from setsqx to sets. This means that it no longer relies on market makers to create a price. I have also seen Porkies tweet of an L2 screenshot. The shares available to buy or sell are not multiplied by 100 but are the actual no of shares available to buy or sell. The 3 quotes on the bottom right with letters after the quantities (MREX,PEEL,SCAP} are from mm's.
The number of shares on the Lse and Euronext remains constant and is kept in check by arb traders using price and fx costs.
Also, on Friday, the value of sells to buys was slightly higher on both exchanges.
