Proper Order To List #Include Files In MQ5 Expert Advisor?

New comment

Is there a proper order in which Include files should be loaded?

Some special order to prevent conflicts?

Why do I ask? I thought something I was reading mentioned it momentarily. I cannot re-locate the reference, but it left a concern in my mind.

Any problem with this?

//+------------------------------------------------------------------+
//| Include Files                                                    |
//+------------------------------------------------------------------+
#include <Expert\Expert.mqh>
//--- available signals
#include <Expert\Signal\SignalAC.mqh>
//--- available trailing
#include <Expert\Trailing\TrailingFixedPips.mqh>
//--- available money management
#include <Expert\Money\MoneyFixedLot.mqh>
//#include <ChartObjectPanel.mqh>
#include <Object.mqh>
//--- std error
#include <stdlibErr.mqh>
//--- Account Info
#include <Trade\AccountInfo.mqh>
//--- Trade Functions
#include <Trade\Trade.mqh>
//--- Date Time
#include <Tools\DateTime.mqh>
//--- Memory Checks
#include <OpenCL\OpenCL.mqh>
// END OF INCLUDE FILES ==============================================

Thank you.

Not really, at least not in this case (if they were not correctly ordered and they needed to be, you would get a compilation error).

The exception is if you have 2 files that depend on one another (and mostly if you want to check-compile mqh files), but that's a very rare issue and definitely not something that happens with standard library files. Or if you did macro redefinitions purposefully in some way...

Properly coded, it shouldn't matter.

If one depends on another, then it, not you, should include it internally.
