I have Ameritrade and on my RTQ I saw 3.70/sh AFTER open. Bid was 3.66 and ask was 4.99. This was 9 minutes after open. I placed a market sell order for the paltry 290 shares I could buy premarket @ 2.20/sh. They then sold for 2.50/sh while I am seeing these much higher bid and ask numbers. This was RTQ that I was looking at, not a recap of pre-market. The bid and ask were changing before my eyes per the above first line of this post. Anyone have a similar experience? What happened? Ameritrade now shows high of the day at 2.60/sh. WTF?
