I can see 700,000 bought16 Oct 2017 12:58
since 11:00 even without allowing for mm ganes on the bid spread and ask so once again the buy sell figures are rubbish.
Although there are apparently quite a lot of sells to 11:00, the drop in bid only happened then and the 700,000 bought since hasn't moved the bid back up ?
Definitely looks suspiciously like market making not market forces.
