I'm currently getting an issue with the Trade Office History tab.
Earlier today every time I deleted old trades from it and then either refreshed or logged in again, I got more old trades from various dates. Now if I delete old trades, I get more from even earlier dates. So far I am on trades from 12th July and probably still going back in time. I've enclosed a link below to show some of the trades.
