Speaking of economic calendars, previously my favorite was the one offered by Markets.com, but unfortunately, it can no longer be accessed by U.S. citizens. I therefore had to look for an alternative.
I believe one group member said he uses the calendar made available by Forex Factory, which is my (second) favorite (too) among those that were left. However, the one I liked the best turned out to be the economic calendar provided by DailyFX.
My third favorite choice is the calendar that can be accessed at Forex.com. I did not like any of the other options available at the time however (2014) enough to include them in my notes.
