How to use MQL5 CDateTime library to add 1 or 2 months to a date

[Michael Reuben Msidada]

I'm trying to add 1 and 2 months to date, but all solutions I find online are about MQL4, which doesn't work on MQL5 compiler. Can anyone suggest an MQL5 way of adding months or days to a date?
Thank you.

Use the MonInc method. It's in the documentation.

• Documentation on MQL5: Standard Library / Panels and Dialogs / CDateTime
  

MonInc

Adds specified number of months

void  MonInc(
   int   delta=1        // months
   )

This wont work: newTime = time + PeriodSeconds(PERIOD_MN1) ?

No, because months and years do not have fixed duration in seconds, unlike minutes, hours, days, or weeks which do have fixed duration in seconds

Can you please provide an example code on how to perform addition? Newbie here.

You should first learn how to code in the MQL Object Oriented Programming (OOP) style. By that I mean, how to code with classes and objects. Once you know that, you will not need an example.

The MQL documentation about OOP is not very "user friendly" in my opinion, so search the web for tutorials on C++ OOP which is on what MQL OOP is based on.

Well I figured it out. For anyone stuck here's what I did.

Declaration
#include <Tools\DateTime.mqh>

struct CDateTime;

datetime StartDate, EndDate;

code:

      CDateTime newDate;

      TimeToStruct(StartDate,newDate);

      newDate.MonInc(1);

      EndDate = newDate.DateTime();
