Not sure the brokers told me that this stock was "red flagged" and that they would not allow any new buy orders because it has been on a restricted list since wed. I have been trading for a while now and have seen this before. They said that this stock is being looked at. As a result I pulled all my shares because this happened to me in 2008 and I lost over $3500.00 on a stock the was on the restricted list. Until I find out more I will be on the sidelines for now.
