You can create your own. The below is mine. You can modify if you want.

Hi Sir! Excuse me, could you explain to me how to correctly place the code in CTrader? I copied and pasted it but when compiling it gave me an error (No algo source file was found in "New cBot.csproj")  Is it possible that you can send a screenshot or something? Thank you!
