Number Of Bars Ago

Sometimes you don't want to test the value of an indicator or bar on the current bar. If you don’t want to test an indicator on the current bar, you can specify which bar you wish to test the indicator on by entering the value in the number of bars ago edit box. For example, if you want to test on a bar one bar ago, you would enter 1 in the edit box. Leaving the value at 0 tests on the current bar.
