[EquisMetaStock Group] Metastock & Spyglass

[jweidner]

I have been using Spyglass (I believe it is now called Fire), with MS9 to plot 
External Relative Strength (ERS) on a chart.  What I wish to do, is plot the 
ERS of several securities on one chart.  I cannot figure out how to do this.  
Does anyone know how to do this?  Thanks for the help.
