Can't call indicator from another

[mate41]

Hello,
i've got this indicator and need to call it from mine.
here is the code of the indicator i have to call:

 protected override void OnBarUpdate()
        {            
            if (CurrentBar < 1)
            {
                Down.Set(0);
                Up.Set(0);
                return;
            }
            
            Up.Set(Close[0] > Open[0] ? Close[0] - Open[0] : 0);
            Down.Set(Close[0] < Open[0] ? Open[0] - Close[0] : 0);            
            
            IMI_.Set((SUM(Up, Length)[0] / (SUM(Up, Length)[0] + SUM(Down, Length)[0])) * 100);
            if (ShowSignal && CurrentBar > AvgLength) 
                Signal.Set(SMA(IMI_, AvgLength)[0]);
        }

thanks for any help

Hello mate41,
It is difficult to say the exact code from the given code snippet, but you can call it the same way one would call a say MACD indicator for example

MACD(12,26,9)[0]; //gets the current value for the MACD
MACD(12, 26, 9).Avg[0];  //get the MACD Average value
MACD(12, 26, 9).Diff[0];   //gets the MACD Diff value

Please let me know if I can assist you any further.

Hello mate41,
So that I can test it at my end can you send the indicator (or still better a toy code*) at support[AT]ninjatrader[DOT]com

Please append Attn:Joydeep in the subject line of your email and give a reference of this thread in the body of the email.

I look forward to assisting you further.

*The "toy" just means something that is a stripped down version that isn't necessarily the whole logic. It makes things easier to rout out.

Thanks for th reply,
there must be 3 arguments and i'll try that...
And yes, that was the solution.

1)
Joydeep -- how is the input to the MACD here (12,26,9, for example) mapped as input to the MACD indicator? Is it their ordering in the properties section of the MACD code? Or ordering of variables defined in the variables region? Or something else? Just to be clear, I mean, how does it know that the "12" input, the first, is to be assigned to the fast EMA, and so on...

2)
Also, the ".Avg[0]" -- is this referencing the #properties code that returns a DataSeries, or does this go by the name of the plot itself? In other words, I don't need a plot in order to retrieve a data series, right?

Hello JoshDance,
1. It sorts the property alphabetically, Fast, Slow, Smooth for example for the MACD.

2. It refers to the DataSeries and not the Plot name. You need to Add the plot only if you want to plot the values on the chart.

Please refer to this sample code if you need to expose any dataseries/values which are not plots http://ninjatrader.com/support/forum...ead.php?t=4991

Please let me know if I can assist you any further.
