Friends, can you tell a newbie what's wrong? I want to find bars corresponding to a certain time, below is the code, but it doesn't work.

       MqlRates rates[];
       ArraySetAsSeries(rates,true);
       int copied = CopyRates(NULL,_Period,0,f_bar,rates);
     
        string a1,a2;
          if (copied>0)
         for(int i=0;i<copied;i++)
           {
               a1 = TimeToString (rates[i].time,TIME_DATE);
               a2 = TimeToString(rates[i].time,TIME_MINUTES);
               if(a2=="14:00"){Comment(a1,"\n",a2);break;
           }

And you, sorry not to offend, didn't count the number of crooked brackets?

[Alexander Mikryukov]

Alexey Viktorov:

I'm sorry, I don't want to offend anyone, but have you considered the number of curve brackets?

This is how I copied it, the compiler doesn't swear.

Searching for a bar by time

The task was to select all the bars of a certain hour at a certain period of time and subsequently calculate the parameters of this bar. That is why I decided to master this function. I am just beginning to master MQL5, that is why I may have some silly questions.

I have understood it and it works.

Gentlemen, help me out here. I am writing an indicator, which draws max and min of the previous day. How to exclude Saturday and Sunday from drawing?

Gentlemen, please help me to understand this. I am developing an indicator that uses max and min of the previous day. How to avoid Saturday and Sunday from drawing?

There are no ticks on the weekend, so the indicator will not do anything. And if it doesn't do anything, it means it won't draw anything :)

First, show me how you get them, these max and min.

MQL4 has a function how to know the month in MQL5?

MqlDateTime - structure to store the date.

TimeToStruct- passes the time to the structure.

Now look at the fields of the structure:

struct MqlDateTime 
  { 
   int year;           // год 
   int mon;            // месяц 
   int day;            // день 
   int hour;           // час 
   int min;            // минуты 
   int sec;            // секунды 
   int day_of_week;    // день недели (0-воскресенье, 1-понедельник, ... ,6-суббота) 
   int day_of_year;    // порядковый номер в году (1 января имеет номер 0) 
  };
