Subject: Re: OT: IBKR portfolio screen
I downloaded TWS. But as I mostly use my tablet I gave their already on it installed mobile app a try. In it I could setup the columns as I wished. Then I tried it with the browser again, the web page. Now for reasons unknown to me the "Edit Columns" button was not greyed out again and I could setup the columns there too as I wished.

I just watched for 1-2 hours the price (bid+ask+last+volume) of the NVIDIA puts I bought last week, on both, IBKR and Schwab. I am baffled because if I am not completely mistaken on IBKR those info compared to Schwab were delayed for many(!) minutes (like Schwab showing "-3.39" for % price change, and IBKR showing that only a full 15min later). I thought IBKR is the pro platform?
