Hey, I know this post is old, but I found a simple solution which I want to share - If you want to prevent trading on the non-farm payroll day, or first Friday of the month, use these two time filters together:
Time filter, specify day start and finish, AND weekday filter, allow Friday. So if both these conditions are true, then you can link them to exclude from trading. It should only exclude Friday which falls on day 1 to 7 of the month.
I'm pretty sure this is working now
