Rec'd the from Etrade this AM:
E*TRADE participants are able to trade both, over the counter, and grey market securities. Due to less regulation in grey market securities, grey market securities are typically sold using a limits price type, oppose to market order price type.
Although, this security may be currently halted, you are still able to put in your order to sell (today). Should it resume, lets say in the gray market, your order will be available for sell provided there is a buyer willing to take on that company.
