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.
