LinRegSlope divergence

["Yarroll" <komin@xxxxxxxxxxxxxx>]

Hello List,

Please have a look at the formulas:

Buy long: divergence(C,LinRegSlope(C,2),0.01)=-1
Sell short: divergence(C,LinRegSlope(C,2),0.01)=1

They are very profitable in tests, just too good to be true. That's because
it is... Tests results back-adjust themselves (ie, you know you should have
gone long 3 bars after the fact, just like the ZigZag indicator).

My question is: what's wrong with the formula?? For all I know LinRegSlope
indicator doesnt change its apperance on the chart going back. MS Help says
the divergence function uses ZigZag ... is that it?

Thanks,
Yarroll
