I Know that Script , I had same problem, what you have to do is increase the Slippage in the Include.mqh that your script should be calling and that's it!!

how to do this?

Hi, I'm trying to initialize my script but it is failed with an error message that it was uninitialized with a reason 0. I looked into the documentation and find the description doesn't tell me anything about the problem. Someone know how to fix this?

Did you figure out the problem in your script?

Maybe you can assist me. I am getting the same frustrating uninit reason 0. I’ve tried moving my slippage up ten pips, didn’t work. I read the manual and traced it back to the OnDeinit() function being called reason being:

before reinitialization due to the change of a symbol or chart period, to which the mql4 program is attached;

before reinitialization due to the change of input parameters;

before unloading the mql4 program.

However I can not seem to locate the mistake in either situation.  

It loaded successfully

It ran the global inputs successfully 

It initialized successfully 

It sent my price alert successfully 

It sent my entry price, stop loss, and take profit price successfully

then it called the  OnDeinit() function

Followed by a uninit reason 0

Follwed by a removal.

Attached it the script along with the function include file.

Thank You

This has already been explained!

It is a script, it is doing what it is supposed to do.

Why do you expect something different?
