Thank you for sending us a message regarding trading PTSC in your account at this time. I apologize for any inconvenience concerning this matter. There are some securities that cannot be traded online such as this one. Most of the time it is due to a corporate action that is processing like a merger, acquisition, stock split or reverse split or some other type of event. There are actually many things that can cause a stock to not be able to be traded online, more than would be feasible in a regular e-mail. At this time I do not have exact details as to why this particular security, PTSC, is not available to trade online. Due to the fact that this order cannot be placed online we are willing to place the trade for you and waive the normal broker assisted trade fee that is usually charged to have a broker place a trade. If you have any other questions or concerns that we can help you out with at this time please feel free to e-mail us again or call us at the number listed below.
