Unable to plot indicator from compiled assembly on another pc

[zextra]

Hi,
I have an indicator that I compile into an assembly called "TestIndicator". When importing the NinjaScript assembly onto another machine the indicator plots on the main price panel only if there are no other indicators loaded. If I load EMA for example, the indicator won't plot anymore. In the output window I see

Error on calling 'OnBarUpdate' method for indicator 'TestIndicator' on bar 20: Unable to cast object of type 'NinjaTrader.Indicator.AAA' to type 'NinjaTrader.Indicator.Indicator'.

What is going on? I am very confused. Thanks in advance!

Hello zextra,

Thank you for your post and welcome to the NinjaTrader Support Forum!

Do you see the same error when you export the file as a source file (not protected) and import it into the other PC?
