Hi John,
We will put this on the list of possible enhancements to only generate HST files.
For the monthly data, Tickstory does produce the MT4 HST files for the monthly time-frame however you will notice that MT4 does not support back-testing for > Daily time frame so no FXTs are generated.
If you are referring to the File export facility, then it does not currently support monthly time-frame. A note has been added to support this in the future. As an interim workaround you could simply export the data from the MT4 history center.
Hope this helps.
