As explained to me: The stock is thinly traded and a short sell restriction occurs when the market maker has insufficant shares to rent to the short seller. Also at certain times of high volitility regulations block short sales.
The second thing explained to me in response to my question, "how do I protect my shares from being rented to short sellers" I was told that shares held in an account with no margin against it cannot be rented out.
I transfered all my shares to another non margin account,
Hope this helps
The games continue, the short sells 100 shares to drop the price making his position better. But now there is a long player jumping it back up to make his look better. Today they blocked the short sellers. Good time to lowball an order , any shares bought are real sales.
