jose,
Thanks for your reply. when I plot this indicator on the same graph as
metastocks centered ma, my lowerband is within 2mil of the ma,
centered correctly, but my centered ma is way above, I think I will
have to start drom begining again to see if rest of formula is
affecting the position.
Regards Robert
