Hi,

The following Metastock formulae for Countback Lines were obviously written
for Metastock 6.0 as they did not work for Metastock 5.11 . Please, can
anyone help write the formulae so that they are compatible for Metastock
5.11 . 

I have had posted a request to this list before more than a week ago, but
have not recevied any response (including from EQUIS) until now. Hope to
get at least someone who is fluent in writing Metastock 5.11 formulae to
share his ideas.

The formulae from EQUIS are reproduced below for this thread in the
postings below.

Thanks.

Regards

Peter Lim
