Paul,
Thanks very much. I performed a search, but didn't use the correct search terms apparently, and in Help, eSignal infers it can't be done. Now, I just need to figure out if .efs needs to be compiled and how it is to be incorporated into a chart. I'm a new user of eSignal, but a 20 year programmer, so this shouldn't be too hard to figure out.
Thanks again,
Stephen

Stephen,
If it helps, EFS is just the core Java Script functionality with additions to support getting of price data, indicators and charting.
So, no compiles, no linking. After creating the EFS all you have to do is load it in the chart (right click on the chart->formulas->(formulaname) ) and it is tokenized and run on the chart.
It is possible to do what you are asking...the main issue will be scaling the study to fit the price range, since at this time, eSignal doesn't allow a secondary y-axis. We have been told this will change in future releases.

Garth,
Thanks for the tips! I've edited the code mentioned below, which includes scaling logic (the additional Y axis would be nice), but I'm unclear what to do to get the chart to recognize the changes. I've been reading the EFS Help and Guides, but it seems they left out this little tidbit. I'm hoping there is a shorter way than removing the study and reinserting it for each change. I bet you know... (hint, hint).
Thanks,
Stephen
