Hello tkaboris,

You need to set the plots to the value you calculated. You can use the public properties for that:

SEMA[0] = theValueForThePlot; 
FEMA[0] = theValueForThePlot;

[tkaboris]

hmm. I actually just want to plot two emas, fast and slow
if i insert this line indicator doesnt work
SEMA[0] = fastValue;
FEMA[0] = slowValue;
I generated this code from indicator template and it suppose to plot but it doensnt.. I am doing something wrong..

Hello tkaboris,

To plot the EMA's you could use the fastValue and slowValue, that code would have to come after where fastValue and slowValue are set. You would have to compile and re apply the indicator to see that change.

When you say that this was from a template what do you mean? There are currently no indicator templates that come with the platform, you can generate a new empty indicator by using the NinjaScript editor. Is that what you had done and then this is the code you wrote?
