CurrentBars[1]

[several]

Whenever I try to reference the previous Bar using CurrentBars[1] I get an error 'outside the bounds of the array'.

Which is the correct method to reference the previous bar?

Hello several,

Are you trying to get the index of the previous bar? CurrentBar is the index of the processing bar, to get the previous index would be CurrentBar - 1. If you are trying to use BarsAgo to get a price you need to use the series for that like Close: Close[1]

I'm just trying to compare a variable which has a bar number stored to the previous bar.

So I've been doing;

If (CurrentBars[0] - 1) == MyVar

But it makes more sense to write:

If CurrentBars[1] == MyVar

Hello several,

You are using the Plural CurrentBars and not the singular CurrentBar, CurrentBars is used to get the index in a multi series script. For example CurrentBars[1] would represent the secondary series. In a single series script you have singular CurrentBar which does not take a bars ago, that's just the index of what bar is being processed. To know what the previous bars index was you would need to subtract 1 from CurrentBar.
