Days of the week - indicator for MetaTrader 5

The indicator shows the current day of the week as a histogram. The histogram rule matches the numbering of days in the MqlDateTime structure:

struct MqlDateTime 
  { 
   int year;           // year 
   int mon;            // month
   int day;            // day
   int hour;           // hour
   int min;            // minutes
   int sec;            // seconds
   int day_of_week;    // day of the week (0-Sunday, 1-Monday, ... ,6-Saturday)
   int day_of_year;    // number of a day in the year (1st of January has number 0)
  };

The "Days of the week" indicator can be applied on the D1 timeframe together with "Volumes" indicator for a visual search of dependencies between days of the week and volumes:
