Error CT0002: ASSEMBLY MUST COINTAIN ALGO TYPE.
30 Aug 2023, 14:47


Hello
I'm creating an indicator from scratch I'm not a programmer but I make an effort. The code of my program has no errors, but at compile time I get the following error.
Error CT0002: Assembly must contain something type.
Please someone knowledgeable help me.

Hi there,

Your code does not look like an indicator code. Can you share the complete code of your indicator?

Hi there,

Hello, this would be a version of the NCATRSD indicator that is currently used in the Ninjatrader platform. Adapted to the ctrader platform If you know of one that is already on the ctrader platform and that complies with the ncatrsd characteristics, you would be so kind as to share it. In any case, we continue with my code to see what comes out lolz.

Hi there,

I am not sure where did you get this code from but it is definitely not a cTrader indicator.
