Actually you should set sell limits.... very high limits set all your shares to sell at $500.... any shares you own that are not being offered to sell can and will be borrowed by shorters..... that is where they get the shares from..... they “Borrow” / “Short Sell” your shares..... lock them up so they cant be borrowed. Do that by putting them up for sale at a very very high price..... and DO THAT RIGHT NOW!
