How to Calculate with date and times?
On several places there are comments like the following (https://www.mql5.com/en/forum/688):
datetime t;MqlDateTime mdt;TimeToStruct(t,mdt);
mdt.day += 45;//or mdt.day = 50; //50 days from the beginning of the month//or mdt.hour += 134; //134 hours in the future //or mdt.hour = 1000; //1000 hours from the beginning of the day
This works but gives incorrect results. example:mdt.day -= 50 gives an negative day and not a day one ore two month in the past.
What is MqlDateTime
useful for if not for calculations?and how do you calculate valid dates?
Attached is a indicator that shows the incorrect behavior of the above method
