So I am a curious wannabe trader dreaming about automated trading. What do the professionals used for automated trading? I'm not talking about Tradestation, I hear the program can be inefficient when it comes to processing code (although this would only matter for super scalping). But maybe I heard wrong. What language do the powerful systems use, and what is the best way to learn to code? (I understand coding takes experience to learn just like trading, so no need to mention it will take me years to master, I know) Thanks for any input.
