Really Strange Error (OO)

[Boob Wood]

This Is My Expert Code.

I am going to have Automatic Trading according another indicator data (Test_SellBuyPoints).

Whenever I want do debug my code and step by step running, I give "Critical error occurred, debugging is stopped", message in line 38 of my code which is 

if(IndHandle<0)

nothing is wrong with this simple "if" statement!

Here is my Complete Code

Maybe something is wrong with the IndHandle value which you use in the if-statement? Have you tried to insert a print statement on line 37 to print its current value?

The IndHandle is 10

Nothing wrong with its value.
