[FuriousM]

Hello,

I'm developping a simple MA crossover indicator.

After few hours asking AI and reading NT8 doc I seeking for help here as Im to the point that my NinjaTrader is broken and my code fine as it is...

I got the Errors as screenshoted : "The name 'Draw' does not exist in the current context. Same for Brushes
Yet i'm using : using NinjaTrader.Gui.Tools;

Thanks for your help.

Hello FuriousM,

There appears to be missing using statements.

Create a new indicator using the NinjaScript Editor.

Copy all of the default using statements from the 'region Using declarations' to the top of your script.

Moving forward always create a new script using the NinjaScript Editor. Do not remove the default using statements.
