I've found that news and world events destroy every single EA in a back test that's otherwise profitable. When you make an EA and back test try looking at the dates it failed, usually you'll find it's actually a non-farm payroll day or a press conference. It's enough to make an otherwise profitable EA look like it fails every time.

Is there a simpler way to exclude dates to trade on, for example I want to exclude certain news days from my back testing. Is there any way to just be able to type in a list of dates instead of using lots of node date filters?
