Aleksey Lebedev:

It's a bit of a mess, isn't it?

I don't agree, because the person is making an indicator, and in an indicator you have to work with arrays from OnCalculate().

...

Pardon my impertinence, but can you show me how to combine your code and mine?

An ancient folk wisdom says: if you want to help a hungry man, don't give him a fish, give him a fishing rod.

If you have any questions, do ask.

time[0] if needed, and religion does not allow to use TimeCurrent().

And how do you know what day is on the 163 bar of the current TF?

[Vladimir Karputov]

-Aleks-:
And how do you know what day the 163 bar of the current TF is?

time[163]

So in the indicator you will get the opening date of the bar with index 163.

And how do I know what day is on the 163 bar of the current TF?

I don't quite understand the question.

int DayN=(time[0]-time[163])/86400;

0 = today's

1 = yesterday, etc.

Print(time[163]) or Comment(time[163]) will print the date/time in human form.

corrected.

[Aleksey Vyazmikin]

Karputov Vladimir:
This way in the indicator you will get the open date of the bar with index 163.

Did an experiment, put 163 and got a line

2016.03.07 18:46:29.062 Start_day GBPUSD,H1: Start day 2016.02.25 03:00:00

And actually should have gotten the date 2016.03.01 00:00:00 !

I guess I'm not very good at explaining what I want to get, let me try again.

I need to make a calculation on each chart of the current TF. The calculation requires to know the date of the upper TF (days). Above I have attached the code - the idea is to know on each bar the maximum price of the upper TF at the time of the bar opening in the current TF.

0 = today's

1 = yesterday, etc.

corrected.

We will get the seconds we need to round up - rounding is the problem.

-Aleks-:

Use TimeToStruct().

[Aleksey Vyazmikin]

Alexey Kozitsyn:
Use TimeToStruct().

I can't figure out how to use it.

The second value requires"MqlDateTime&dt_struct// structure for taking values", but I don't understand how to use this MqlDateTime.
