StringToTime

Thank you very much!
 
Maxim Khrolenko:
Much obliged!

Terribly slow and not optimal to handle string variable conversions.

Fill MqlDateTime structure and get full date and time from it.

Thank you very much!

We don't look for easy ways. Way to go...

Write him a little example ;)

Interesting to see how it works in code

I can't find an answer to the question, how to write a time value corresponding to the given parameters into a variable of datetime type based on 6 variables of int type (year, month, day, hour, minute)? Then I need to find the index of the candle that opened at that time, but that's not a problem for me. If anyone has a link where you can find the answer, please, I'll figure it out on my own.

MqlDateTime dateTime;

dateTime.year = 2018;
dateTime.mon = 3;
dateTime.day = 30;
dateTime.hour = 21;
dateTime.min = 15;

datetime _Time = StructToTime(dateTime);

What day of the week does that make it? Have you checked? Just wondering if it calculates it by itself during the conversion or not.

Even these two: day_of_week and day_of_year

If you put it back into the structure afterwards.

  TimeToStruct(_Time, dateTime);

it'll show up all right.

day_of_week = 5

day_of_year = 88

День года - 879007969
День года - 32

It doesn't work when day_of_year is filled in (

 


A very strange pause of 22 seconds. Who can explain?
