Good afternoon. Question about OBJPROP_TIMEFRAMES property identifier of graphical objects... I wrote this script to create a Horizontal Line graphical object (see below).

Question: Why, although the ObjectSet(object_name,OBJPROP_TIMEFRAMES,PERIOD_H1) function explicitly states that the object should display ONLY on timeframe H1, the created object also displays on timeframes (at least) H4, M30, M15.


https://docs.mql4.com/ru/constants/objects/visible


Another constant is OBJ_PERIOD_H1


Yes, thank you it helped... But I'd like to understand why ObjectSet(object_name,OBJPROP_TIMEFRAMES,PERIOD_H1) option doesn't work (as it should)? Is it glitches in the language itself?
 
DanLett:

i.e. while the current bar[0] is being built the previous one is being defined


As an option:

datetime last_time;   // глобальная переменная

...

int start()
{
   if (last_time != Time[0])
   {
      // Ура, новый бар!
      last_time = Time[0];      // запоминаем новый бар
      //... ваши расчеты с плюсованием
   }
   
... дальше работаем

De facto both PERIOD_H1 and OBJ_PERIOD_H1 are just an alpha substitution of some numeric value.

OBJ_PERIOD_H1 = 0x0010 (for current build) = 0001 0000 (binary)

PERIOD_H1 = 60 (for this build) = 0011 1100 (binary)


As it is easy to replace, you accidentally put 4 timeframes instead of one - H4, H1, M30 and M15


And instead of calling ObjectSet(object_name,OBJPROP_TIMEFRAMES,0x0010) (which you wanted to do) you have called

ObjectSet(object_name,OBJPROP_TIMEFRAMES,0x3C).

 
datetime last_time;   // глобальная переменная

...

int start()
{
   if (last_time != Time[0])
   {
      // Ура, новый бар!
      last_time = Time[0];      // запоминаем новый бар
      if(close[1]>open[1]) 
xBost_b=xBost_b+((close[1]-low[1])*10000);
   }

what is Time[0] and how does it affect 1 time plus ?! just a little confused...

Time[0] is the opening time of the most recent (current) bar. As soon as a new bar comes, it changes.

Type Time in MetaEditor and press F1 for details

Will read it now! thank you very much!

Then don't forget to look at iTime()
 
   datetime last_time;   // глобальная переменная
  int xBost_b;
  int xBost_s;
double hi=High[1];
double op=Open[1];
double cl=Close[1];
double lo=Low[1];
int Sum_xb;
int Sum_xs;
 
 if (last_time != Time[0])
   {
      // Ура, новый бар!
      last_time = Time[0];      // запоминаем новый бар
      if(Close[1]>Open[1]) 
xBost_b=(hi-cl)*10000;
Sum_xb=Sum_xb+xBost_b;<---------не плюсует,выдает такое же число как и xBost

      if(Close[1]<Open[1])
 xBost_s=(cl-lo)*10000; 
Sum_xs=Sum_xs+xBost_s;    
Comment("\n kolvo_b=",xBost_b,"\n Sum_xb=",Sum_xb,"\n kolvo_s=",xBost_s,"\n Sum_xs=",Sum_xs);

   }
how do you make it give you a plus every time?
 
DanLett:
how do I make it add up every time???
Theglobal variables should be outside all functions. Send the sums there too. or declare these variables as static

Take last_time out of start() and declare it static
