Alexey Viktorov:

It is very likely that after renaming an object, it is not yet available to be accessed. You can try putting ChartRedraw after renaming. If that doesn't work, then you need to build the sequence somehow else.

ps; Another option is to repaint with sparam name first and then rename.

Thanks again!!! What would I do without you? ))))

Example inFibonaci RR code -

Thanks for the example, but this is just setting trading levels. I am interested in setting Fibonacci levels like 0.0%, 23.6%, 38.2%, 50%, 61.8%, 100%, 161.8%, 261.8%...

https://www.metatrader5.com/ru/terminal/help/objects/fibo/fibo_retracement

The auto indicator draws by default and by standard Fibo levels. There should be a source code of Fibo tools in the terminal that could be changed or copied from it... I can't find it, if you know it, please give me a hint.

Or how to add the following levels in custom indicator:0.0%, 23.6%, 38.2%, 50%, 61.8%, 100%, 161.8%, 261.8%...

   ObjectCreate(chart_id,name,OBJ_EXPANSION,nwin,time1,price1,time2,price2,time3,price3);
   ObjectSetInteger(chart_id,name,OBJPROP_COLOR,Color);
   ObjectSetInteger(chart_id,name,OBJPROP_STYLE,style);
   ObjectSetInteger(chart_id,name,OBJPROP_WIDTH,width);

   if(ray>0)ObjectSetInteger(chart_id,name,OBJPROP_RAY_RIGHT,true);
   if(ray<0)ObjectSetInteger(chart_id,name,OBJPROP_RAY_LEFT,true);

   if(ray==0)
     {
      ObjectSetInteger(chart_id,name,OBJPROP_RAY_RIGHT,false);
      ObjectSetInteger(chart_id,name,OBJPROP_RAY_LEFT,false);
     }

   ObjectSetString(chart_id,name,OBJPROP_TEXT,text);
   ObjectSetInteger(chart_id,name,OBJPROP_BACK,true);

   for(int numb=0; numb<10; numb++)
     {
      ObjectSetInteger(chart_id,name,OBJPROP_LEVELCOLOR,numb,Color);
      ObjectSetInteger(chart_id,name,OBJPROP_LEVELSTYLE,numb,style);
      ObjectSetInteger(chart_id,name,OBJPROP_LEVELWIDTH,numb,width);
     }

Please advise

Maybe I'd learn to think logically.)))

the example I gave above - it has just the setting of levels. If you're asking, would you mind opening the code and checking?

Thanks, yes there is, it's a bit confusing but I'm trying to understand) thanks

What the code would look like in Mql5

extern int    StartHour   = 12;    //Час начала торговли(терминальное время)

int start()
{
if  (Hour()==StartHour)
    {
     OrderSend(Symbol(),OP_BUY,Lot,Ask,0,Ask-StopLoss*Point,Bid+TakeProfit*Point,"советник",MAGIC,expiration,Blue);
    }  
return(0);
}

Dmitriywelcome:

How would the code look like in Mql5

   MqlDateTime tm;
   TimeCurrent(tm);
   if(tm.hour==12) {
    ...
   }

Exactly as it would look in mql4

A bit of help

MqlDateTime

The date structure contains eight fields of typeint.

structMqlDateTime { intyear;// year intmon;// month intday;// day inthour;// hour; // hour intmin;// minutes intsec;// seconds intday_of_week;// day of week (0-Sunday, 1-Monday, ....,6-saturday) intday_of_year;// sequence number in a year (January 1 has number 0) };

Nice auto-drawer) with different objects, levels, timeframes, thanks a lot

I tried everything I could out of what you've told me, I twisted and turned, but all the same colour lines in MT5. In MT4 it re-colours in a normal way, without any delay.

how to organise an algorithm in one indicator to take points and transfer them to another buffer.

- To draw the trend lines. (as on the picture)

-----------------------------------------

I tried everything with gut feeling, they are drawn but in strange places.

I attached the indicator - it works - but these lines cannot be adjusted.
