I never tried to
exploit it as it didn't seem any better than other things I
use.

[Metastockusers] Re: Code for MAMALionel &
JB,Thank you for your help with the ".dll".It loads seperate
indicators for MAMA and FAMA. However when I load them onto a chart,
individually, the FAMA is displaced upwards by some considerable
amount. When I combined the two into one indicator the results
appeared to be more realistic. Have either of you resolved this
apparent inconsistancy?Regards,Keith--- In
