If I use return() -> error5004

New comment
I try to use the value outside of the "for".

but when I use "return(Max_Value);"

, error 5004 appear


or print nothing

What should I do?


File "Max"

ex) 

2000-00-00 0:00,00

2000-00-00 0:00,00

2000-00-00 0:00,00

00 => Value between 1 and 100

int Past = 2;
int BarsCount = 0;
int i;

bool Max_Average=False;
bool NewBar= false;

double Max_Value;

int data_size = 8650;


datetime PreviousBar;

I have removed the huge spaces in your posted code. Please consider others and make your code as easy as possible to read. Code with 10 empty lines between lines of code is not easy to read.
Alain Verleyen :

And please stop double posting again and again. You already have 1 thread on the same topic where people took time to answer.

I will remove this one (sorry Keith).

I deleted it, but I just answered and I did not double post.

Sorry I don't know what happened, I was answering to the OP, not you. You can post of course.

All right. Never mind.
