I had a problem today with a regular Naz stock "LVLT" Level 3. All afternoon it showed on my Ameritrade streamer that it was up .14, but at the same time, the low of day was highlighted in the day low box. It was correct in my account (down .07), but not on the streamer. The only time it corrected itself, was when I opened the Level 2 window. As soon as I closed it, it went back to showing up .14 with the wrong price.
I don't like that they won't let me buy certain stocks. I was told that they have approx. 30 stocks that we can't buy. One I already own, and they won't let me buy more to average down. The other, I've watched go up from .03 to .10 and can't profit from it.
But I do like that because of the number of trades I do, I was able to negotiate what I pay for commission, to a lower price.
