I bought MRO yesterday at $3.43 and tried to sell it this morning at $4.75. The price kept freezing and my limit orders were not working despite hitting the bid. At $4.35 I put in a market order, but it also wouldn't sell. The bid went to 0.00. I figured some error and I cancelled my market order after a minute or so getting worried I'd be filled at $0. I eventually sold it at $4.15 and the price is currently frozen again at 3.94. What is going on? Are there just not enough buyers and sellers in that stock? there is 8m traded this morning though...
What time were you trying to sell the stock? Before the open or after? If it was before, then you might need to specifically send a pre-market order via etrade. I don't use etrade but other brokers I do use have a separate trading interface for pre and post-market trading. Otherwise your post doesn't make sense - if you were long the shares you should be able to sell them at whatever price you want. If I had to guess, you put in an order before 9:30am and you didn't use the pre-market interface so the order was queued and wouldn't go active until the open.
