So I find I am missing something. Doing back testing we can define an interval, this interval is always a previous "bar" of a length you define (unless you have the intra-bar checked)
However, when I use the "bar" parameter in the method in my formula the bar interval is defined in the method (unless override is check on back testing)
So do I have to rewrite all my methods in the formula to the interval I want to use to simulate the "interval" setting available on back testing?
