Dear Metastock Gurus,

I would like to adjust the number of periods for some certain forumlas depending on whether it is a weekly chart or daily chart. For example, if I want to calculate a 10-week moving average, then the number of periods will be 10 for weekly chart and 50 for daily chart.

The problem I am facing is that I do not know how to get the script to detect whether the chart is currently a weekly chart or daily chart.

Can someone advise?

Thank you very much in advance.

       Only way I can think of is to use the date functions and subtract dates and
compare differences. You could also use the input function. I usually have copies of the
same indicator with one variable different when I run into this situation.   

There are two ways to test for the chart periodicity.  Using MSFL you can run a relative slow and complicated series of formulas to make the discovery.  It works most of the time, but on lesser traded commodities it (allegedly) occassionally throws back false positives and true negatives. (I don't use this method myself so cannot guarantee the accuracy of any results)

The other option is to write an external function as the information you are seeking is already available to these external library functions and extracted with absolute minimum error.


Hope this helps.
