I can confirm that this problem is fixed in TWS 875, now released for both browser and stand-alone users.
charts don't function properly today: update ok but are not responding to inputs like change settings, add indicators or refresh. again, often mkt depth is missing on some markets; HSI futs and CL futs affected the most frequent... closing-re-opening DOM/ BT won't do.
IB fixed the P&L issue with their latest release. Thanks IB! You're SW release process might be a little error prone, but you guys are great at addressing customer reported bugs!
