Scrollable ATR

[davydhnz]

Sometimes we might want to scroll back the chart and find ATR values without using a plot,
but just by using OnRender.

I've been trying and let's just say my head hurts

high0 = BarsArray[0].GetHigh(ChartBars.ToIndex - 1);
low0 = BarsArray[0].GetLow(ChartBars.ToIndex - 1);
close1 = BarsArray[0].GetClose(ChartBars.ToIndex);
double trueRange =
Math.Max(Math.Abs(low0 - close1),
Math.Max(high0 - low0,
Math.Abs(high0 - close1)));

the default Ninja atr uses a plot with Value, but I would have to reconstruct the values necessary for the period.

If only I could use ATR(12)[ChartBars.ToIndex];

Long shot, but any advice from the community and I'm all ears

Hello davydhnz,

Thanks for your notes.

You could consider accessing the ATR indicator value in OnRender() using .GetValueAt() on the ATR() system indicator method.

For example: ATR(20).Values[0].GetValueAt(123);

See the help guide documentation below for more information.

Otherwise you would need to come up with your own custom logic to calculate that information. This forum thread will be open for other community members to share their insight on possible custom logic to accomplish this.
