EasyLanguage, 3rd party data refresh window on timer? tradestation

Does anyone know: If I was using a datafile rather than a feed and I wanted to update the window on some kind of timer in a IF THEN loop?

 

I read something about doing a runcommand(".RF")

Someone will more experience might know a better way to force the window on a timer to check the file say every 30 seconds?

 

Thank You in advance.

Maybe using something like https://www.autoitscript.com/site/autoit/ will help?

Thanks Jharris. As a last resort I will use something like what you suggested. But ideally I want to use tradestation native scripting language Easylanguage. which will then work as a template in every new chart.
