not too bad- they won't take it at that but prob .12 or so...I speak from fat-finger experience !! One day (long ago) I though I lost $40,000.00 because I pressed the wrong key... I ended up loosing $7000.00 instead of gaining a few thousand. They won't take it at your number- the give you at the lowest..Man, to this day..I get nervous and stare at the order before I push the final sell or buy ! I lost a chunk of change but man- it wasn't 40k and I was happy.
