BarsAgo appears to be lagging

[Turtle Trader]

Hello,

As soon (i.e. immediately) as a new bar opens, I am needing to start scanning the prior bars.

I must have something wrong because it looks to me like on the first tick of a new bar that the [0] bar pointer has not yet been moved to the new bar.

Below is the code to indicate what is happening, if you put it in an indicator, on a new bar [0] is still pointing to what I would have thought would now be [1].

(If you run it on a tick chart it will move fast enough to see what is happening.)

Is this so?

If possible, how can I reliably start processing backwards on the first tick of a new bar?

Do I need to treat [0] as [1]?

If so at what point does [0] move to the current bar, making that process invalid?

Thank you.

if (CurrentBar < 1)
return;

Print("Bar 1 Open = "+Open[1].ToString());
DrawArrowDown("tag2", true, 1, Open[1] + TickSize, Color.Blue);
