What is the cause of the error (expressions are not allowed on a global scale )

Hi

What is the problem the following code?

string stat3()
if (stat1>stat2)
    return("buy");
else if (stat1<stat2)

  return("sell");

Load your code (not only this snippet) in a different editor and count the brackets: { and } and ( and ) and then start to find where have you either one of them too many or too less.

2. void OnTick()
     {
   
     }
   ^^^^^^^^^^^ OnTick has ended. vvvvvvvvvv everything below is on global scope.
