Need Help in Addtocomposite

Dear All,
I am trying to make equal weighted price index with ATC. I am facing problem as some of my stocks don't trade daily. hence my index has very volatile graph. Is there any way by which i can use previous day close (or data) if stock of my portfolio is not traded on any particular day.

Thanks & Regards
Vineet
