[zhaofangoo]

hellow, I have upgraded ninja7 to ninja8 ,there is a frequently used indicator no work in ninja8 , can you help convert it? thanks!

Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Plot1"));
Add(new Plot(Color.FromKnownColor(KnownColor.DarkViolet), PlotStyle.Line, "Plot2"));
Add(new Plot(Color.FromKnownColor(KnownColor.Firebrick), PlotStyle.Line, "Plot3"));
Add(new Line(Color.FromKnownColor(KnownColor.DarkOliveGree n), 0, "Zero"));
Add(new Line(Color.FromKnownColor(KnownColor.Khaki), 10, "Ten"));
Add(new Line(Color.FromKnownColor(KnownColor.Lavender), 60, "Sixty"));

}

if( Close[0] - Close[1] <= 0 )
{

}
else

}

Var5.Set(SUM(Var2,8)[0] / SUM(Var4, 8)[0]);

Var6.Set((1-1/(1+Var5[0])) * 100);

Var7.Set(EMA(Var6, 3)[0]);

Var8.Set(EMA(Var7, 7)[0]);

Var9.Set(MIN(Volume, 50)[0]);

Hi zhaofangoo, thanks for posting.

The original script is quite short, so I converted it for posterity. To summarize what I did: Add(new Plot.. is now AddPlot(), DataSeries are now Series<T> objects, initialized in State.DataLoaded, and anywhere you see .Set(), we set the Series<T> object at the 0 index: Var1[0] = Volume[0]/10000; //same as Var1.Set(Volume[0]/10000);

Kindest regards,
-ChrisL

thank you very much ChrisL!

thank you very much ChrisL!

It seems the indicator plots multiple EMA of volume and ratios of some oscillators of the volume with more EMAs, that make it a very lagging indicator. Frankly, I can not see how this indicator is frequently used as you noted, and is of any value without some description of the use.

It would be nice if at least you explain what this indicator does and how it is used, and perhaps provide a reference that gives a detail explanation of the logic.

Cheers!

Good morning ChrisL, nice of you to assist a trader. I was instructed that help of this sort isn't a service you all provide and I just needed a conversion as well https://ninjatrader.com/support/foru...ion-to-ninja-8

Hi Justina, Unfortunately, we are not able to convert indicators on request. We will convert indicators that serve as a good example of how to perform a conversion if they are short and quick to convert. The script you linked requires a more advanced method such as converting the Plot() method to the OnRender method. More reading on this subject can be found here:
