Retrieving a value from a custom indicator from within a custom indicator

[jkmott59]

Hi all,

I'm using the Market Analyzer and have some custom indicators.

I have 2 custom indicators on different time frames. Call the A2 and B60, where A is on 2 min and B is on 60 min.

While A2 is running I want to retrieve the value for B60 -- the value that B60 passes to Plot0.Set

I know about this to add the data series

protected override void Initialize()
{
Add (PeriodType.Minute, 60);
.. other initialization
}

and I know that I use BarsArray[1] to access that series.

I know how to call the indicator

B60 oCustom = this.B60(this.BarsArray[1],0);

I'm guessing that a field in oCustom contains the result? Which one?

Thanks in advance,

john

Hello jkmott59,

Thank you for your post.

oCustom[0] would access the value of the B60.

Thank you! Question about # of bars needed

Thank you for that help. I'm getting the error about not having enough bars available to the called indicator (B60). It uses an EMA 8 period but other than that does not rely on any bars in the past, and does not use the CurrentBar test.

I can adjust the CurrentBar in the A2 indicator but how do I know what to set it to?

its not clear to me when the BarsArray[1] gets populated.

thank you again for your help.

Hello John,

Thank you for your response.

There would need to be at least 8 bars loaded. So if the A2 indicator is calling the B60 I would use the following line at the start of the OnBarUpdate() for the A2:

if(CurrentBars[0] <= BarsRequired || CurrentBars[1] <= 8)
return;

That took care of it, thanks

Setting the bars to 20 made it happy. Thank you for your prompt response, this has added a valuable skill set to my ninjatrader toolbox.
