My understanding is that shorters borrow shares from brokers, if brokers do not have shares to lend to the shorters they have no way of shorting, therefore if your shares are locked into a price they can’t be loaned out, I have mine locked at a price so my broker can’t use them
Heck yes,, Just put sell order for 25 cents , can either be for good til cancelled or even put sell order in daily.. Keeps MMs from borrowing your shares on Margin..
