Hi JIIENDRA,
I suggest that you go through the MS manual and study the Equis formula primer (
http://www.equis.com/Customer/Resources/). Also become a member of the official Equis Metastock Forum and of the Equismetastock Yahoo group, and study the formulas posted there. In no time you will be able to create your own experts.
