Your coded indicator in use or standard or downloaded from somewhere?

What forum was that?

There you have it - you have unreasonable values somewhere, too little or too large! Overflow is a bad error, it takes a lot of time to track down. Krog made a tracing technique thread, read it and go from there. I'm not sure you have a problem with Int value, start from double values, especially those, which go into components.

I asked in other .Net forum and received these answers

1-GDI+ library tries to draw with a very large Int32 value, so make sure when you create a Series object the values to assign are not out of reasonable bounds.

2- allocating a lot of GDI objects that are not disposed in a timely manner.

And thanks god i donot know how to use them !!!!!

Search for overflow error, ton of info out there, should definitely be of help. Don't forget to add "C#" into search phrase.

I face that error alot when trying to add extra lines to an indicator , The indicators compiled well and the generator runs everything is ok but the graph window collapsed

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

System.OverflowException: Overflow error.

You cannot use "iBar" because it is already used. Use "br" or some other name in that context.

I Started This Topic to discuses the error raised when compiling indicators , people like me with no coding experience may face some difficulties to fix these errors even they appear to be simple things.

1st:
ERROR: Indicator compilation failed in file [Donchian One Band.cs]
Line 179 Column 38: A local variable named 'iBar' cannot be declared in this scope because it would give a different meaning to 'iBar', which is already used in a 'parent or current' scope to denote something else.

THE IDEA OF Indicator: to draw only one band ( if trend is up so draw lower band && if Down draw higher band but the previous err raised ,BUT when i looked into the original DC i find that the iBar already used twice without any problem

NB: i used the logic of two indicators ( DC original & Gann HiLo activator )

Donchian One Band attached

Thanks for help in advance
