Good afternoon. I have solved the issue of passing data from the indicator through the buffer to the Expert Advisor with some crunch. But again a mishap, the passed value comes with a delay of several bars ((.
In the indicator, from the place where I pass the flag to the buff (0,1,-1) I build trend lines in the indicator using these values. In the indicator everything is rendered as it should be, but the same calculations in the Expert Advisor draw the levels with a delay of several bars.
What may be the problem? Ask me a vector code.

Please give me the code

[Dimka-novitsek]

Good day! Could you please tell me if the indicator can switch timeframes?

[Дмитрий]

In the indicator:

   
   Buff_Sign[];
   int init(){SetIndexBuffer(5,Buff_Sign);}

   int start(){
   Buff_Sign[i]=-1;
   /*Условие для Crit: Crit=0 Crit=1 */
   Buff_Sign[i]=Crir;     //это значене уходит в буфер
   
   if(Buff_Sign[i]==0 || Buff_Sign[i]==1){/* расчет для тренд. линий */ }}

in the EA:

 double Sign=iCustom(Symbol(),0,"Sign",5,5);     
   if(Sign==0 || Sign==1){/* тот же самый расчет для тренд. линий  только берется max и min*/ }

The end result is:

That's about it. What else to add?

Dima! I'll give you the link, of course, but don't blame me when all sorts of nonsense and glitches start to occur. This is not an standard solution for mql.

Here is a library with functions that can switch timeframes and not only timeframes.

Good afternoon.

This is how I draw the line in the indicator

           string VLINE_PT=OBJECT_PREFIX+TimeToStr(iTime( NULL, 0, f));
           ObjectCreate(VLINE_PT, OBJ_VLINE, 0, T, 0);
           ObjectSet     (VLINE_PT, OBJPROP_TIME1, T);
           ObjectSet     (VLINE_PT, OBJPROP_WIDTH, 2);
           ObjectSet     (VLINE_PT, OBJPROP_STYLE, 0);
           ObjectSet     (VLINE_PT, OBJPROP_COLOR, Red);

I try to remove it like this

ClearVLine();

void ClearVLine() 
{ 
  for(int i=ObjectsTotal()-1;i>=0;i--) if(StringFind(ObjectName(i),OBJECT_PREFIX)==0) ObjectDelete(ObjectName(i)); 
}

it's not deleting, what's the problem?

[Dimka-novitsek]

THANK YOU all!!!!!!!!!!!!!!

Can you tell me if there are any standard functions used in MQL4. For example, if there is an iStochastic, is there any way to find out how the firm has described them?

It doesn't clear, what's the problem?

Where is OBJECT_PREFIX initialised?
