Thanks Mike. I'm not using trade delays but I am using exrem. However, the barssince funcion was only used to remove more complicated sell rules to try and isolate the fault. It is still buying when the stoch is falling or above 50 - and surely the code as is should re ruling this out?
You say avoid Exrem - is this in all cases or just for fixed bar exit? Unless I'm exiting after a fixed period, is exremspan better? I'm really confused....:-( Thanks for any further advice....anyone? Rich --- In [email protected], "Mike" <sfclimb...@...> wrote: > > A couple of things to consider: > > 1.
