I have mixed opinions on the whole put a high sell on your shares so they can not be shorted but I know some brokers will not let other brokers borrow shares if they have a sell on them but I think that is only at certain % above current value. If anyone has a clear answer to this I would love to know it. At the end of the day most all brokers are so corrupt that I don`t think they follow any rules in the OTC. Still the wild west of stock trading but still the best place to be!
