You have to submit a sale order... so put a limit sell order in for $4 for the longest duration allowed. If TD rejects it just redo it and eventually they will accept it.
If you have a valid sell order brokers cant loan out your shares to shorts.
ONLY 2 DAYS LEFT FOR THE SHYSTERS RUNNING TPTW TO ISSUE THEIR 10K! In the first place there is no such thing as LOCKED SHARES for TPTW or for any other ticker. Either the shares owned by an individual day trader are made available for sale or they arent. If an individual doesnt put a sell order in they cant be sold.
