Use Open[-1] in NT 8 Error
Hello, I build my strategy on NT7 and now I try migrate this, But I have a problem whit the Open[-1]. When I run with historical data it shows this error:
Strategy 'Opti': Error on calling 'OnBarUpdate' method on bar 62: You are accessing an index with a value that is invalid since it is out-of-range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

You are actually technically asking for information on a bar that is in the future where no information exists yet. In programming-land, arrays don't have indexes with a negative number and that's why the application threw an out-of-bounds exception.
I would guess you meant to compare the current bar with the bar before it, so you would want to compare [0] with [1].
