Indicator Dynamic Color Not Working

[soloaudio]

Hi, two issues that need your help:

1. I created a new supertrend indicator that plots the line in different colors based on the CCI level. If CCI is greater than zero, color is set to green; if less than zero, color is red; if zero, color is yellow However, when I displayed the indicator line on the chart, it always shows green color. Any idea? See attached code.

2. Separately, I created a strategy that added the above custom indicator. When I run the strategy in the chart, the indicator line is not shown at all.

Please advise.

Hello soloaudio,

Welcome to the NinjaTrader Support Forums!

I see inside of your Indicator that you are defining a "public DataSeries Direction" inside of the Properties but you are not declaring it inside of the Indicator. You will want to declare it inside of the Indicator itself. Note that if you do not want to plot then you may use the color Transparent.

I believe the same issue is going to be with your Strategy as well.

Let us know how that works out for you.

JC,

1. The coloring of "Trend" works fine after I added the line below. Didn't know the second indicator plot ("Direction") had to be included even though I don't need to plot it. Any reason?

Add(new Plot(Color.Transparent, PlotStyle.Line, "Direction"));


2. The strategy is able to show the Trend indicator plot once the strategy has been enabled. I thought the plot would be available immediately after the strategy is added to the chart but that's not the case..

Thanks.

You should probably see an error in your log, resulting from trying to access the undeclared object in the Values array.

Hello soloaudio,

Running your code since you have a "try-catch" it appears that is is plotting the correct values of the lines but when you try to call "Direction.Set()" NinjaTrader does not have a declared value for this and goes into the "catch" statement which skips over the PlotColors.

It is always important to declare and set/initialize objects before trying to access or modify any code to ensure proper values.

Thanks very much!
