In order to use it, you need to turn on DLL Imports in your Metatrader platform options, because it calls a DLL to get your timezone, as well as another to read the ForexFactory web page to get news information. (Be aware it will write out .XML files to your expert/files folder).

The indicator has settings so you can filter out (or in) news announcements of High, Medium, or Low impact, as well as those with the word "Speaks" in them. You can have it display the minutes till (and info about) the next announcement, or the next two. And you can adjust the colours of the text.

You just apply it to your chart, set your desired options, and it will give you announcement info relating to either currency in the pair on the chart.
