Beno,

wolfe has a unique trailing stop method. It exits from the float....like if you set it at 10 bucks and use a 50% setting it will start to trail at 10 bucks and if you retrace by 50% it will exit...but if you do not retrace it will keep raising your TP as the price goes in your favor...

But the unique thing is that it calculates off the aggregate float not the individual trades..

P.S. I refer to this method as WFM (wolfe floating managment)
