Or just email the broker and formally request that none of your shares be lended to somebody else. Then no pre-set sell order is needed if broker will not allow a sell order for a big dollar amount.
Be careful will low level sell orders in case there is a SHORT SQUEEZE approaching Nov 30 (35 day rule??). The price could skyrocket fast (i only hope and i am not educated i these things so i could be wrong).
