the way i read it was, if you only sold part, its about to fall? again, i have been up a long time, and even longer now, but it sounded like, sell if you cant sell all for a profit, at a loss?
sorry, maybe i read it wrong.
also, if you change the price, per your example, you will lose another fee.
thats the way it is w/amtd, etc. you get less and pay the fee.
