I rebooted my computer and logged on again. The same. No change, the ask and bid quotes still stuck at the same values as before, but in my other account that I was not using today everything is fine.
Well, beats me. Something is wrong, but what and where exactly is the problem? I deleted the tickers with stuck quotes and then inserted them. This did not help.
I missed a very good trade today that I would have taken if everything was working OK. It was a swing trade in NQ. This is the second time in a row that I am missing a big swing in NQ because of some weird TWS problems. This is getting unacceptable.
