I don't think it is a ticker related issue, as i also notice it on multiple of stocks on NASDAQ as well as NYSE exchange. Seems TWS is not able to relay the data to display it on charts, because you still can see the data (Bid/Ask/Mid/spread) etc in your portfolio. So the data is being received from exchange to TWS, but TWS has issues.
