Modified from someone else code here (I'll get the name later). For MQL4, Build 971.

Hopefully this will not upset anyone, but... you never know.... 

Your comments and improvement suggestions appreciated. 

DeInitialization Code Snippet For DeInit Reason Text

Use this code function to enhance your Deinitialization journal entry with the actual reason the Expert Advisor was Deinitialized.

Updated For Metatrader 4, Build 971.

If you uncomment ObjectsDeleteAll(), and you later wonder where all your arrows and lines went on your chart, it is because the ObjectsDeleteAll is doing its job. Just Re-comment it to restore your chart objects.

Remember to use Cntrl + "," to align your code for pretty printing.

void OnDeinit(const int reason)

  {  

Print(EA_Name," is Deinitialized for Reason ",IntegerToString(reason)," ",func_GetDeInitReasonText(_UninitReason)," on ",Sym,", Time Period",_Period);

//ObjectsDeleteAll();

// EventKillTimer(); 

}// End OnDeinit
