Post From: C2447 error when compiling Advanced Custom Studies

Hello,

I’m encountering Error C2447: '(': missing function header (old-style formal list?) when I try to compile my custom strategy script. The error seems to be related to function headers or syntax, but I’m unable to pinpoint the exact cause.

I’ve tried reviewing the function definitions and headers, checked for missing function headers or syntax errors in my custom function declarations but to no avail.

If you could help pinpoint the problem and suggest how to fix the missing function header or any other related issues, I’d greatly appreciate it. Full script is below.

Thank you for your assistance!

Best regards,
Mark
