Can you see my example code in this comment #99

[Marco vd Heijden]

Oh ok that code.

ObjectCreate() also needs the chart ID:

bool  ObjectCreate(
   long         chart_id,      // chart identifier
   string       name,          // object name
   ENUM_OBJECT  type,          // object type
   sub_window   nwin,          // window index
   datetime     time1,         // time of the first anchor point
   double       price1,        // price of the first anchor point
   ...
   datetime     timeN=0,       // time of the N-th anchor point
   double       priceN=0,      // price of the N-th anchor point
   ...
   datetime     time30=0,      // time of the 30th anchor point
   double       price30=0      // price of the 30th anchor point
   );

As the first parameter.

int OnInit()
  {
   Print("Outside");

   ObjectCreate("Object Outside",OBJ_LABEL,0,0,0);
   ObjectSetInteger(0,"Object Outside",OBJPROP_XDISTANCE,20);
   ObjectSetInteger(0,"Object Outside",OBJPROP_YDISTANCE,20);
   ObjectSetString(0,"Object Outside",OBJPROP_TEXT,"Outside");

   if(DayOfWeek()==5)
     {
      Print("Inside");

      ObjectCreate("Object Inside",OBJ_LABEL,0,0,0);
      ObjectSetInteger(0,"Object Inside",OBJPROP_XDISTANCE,20);
      ObjectSetInteger(0,"Object Inside",OBJPROP_YDISTANCE,40);
      ObjectSetString(0,"Object Inside",OBJPROP_TEXT,"Inside");
     }
  }

But you start with the objectname.

Also you can specify a base corner/anchor point.

I am just worrying that I couldn't explained my issue that I want to ask did you tried it, please? Then you can know what is my problem with that code.

I just try like this - 1. I added my example file to the chart then I close MT4. 2. Open MT4 - then I do not see my Inside Label Object.

That's what I try to find solution to my issue. : /

---

Maybe I will be for sure Monday.

( when I think this is so easy I spend a lot of time for that easy things - when I think this is so hard that I did them so easily... - Almost all of what I want to do. first I try to read documentation... )

[Marco vd Heijden]

I tried it and there are two objects shown.

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//---
      Print("Outside");

   ObjectCreate(0,"Object Outside",OBJ_LABEL,0,0,0);
   ObjectSetInteger(0,"Object Outside",OBJPROP_XDISTANCE,20);
   ObjectSetInteger(0,"Object Outside",OBJPROP_YDISTANCE,20);
   ObjectSetString(0,"Object Outside",OBJPROP_TEXT,"Outside");

   if(DayOfWeek()==5)
     {
      Print("Inside");

      ObjectCreate(0,"Object Inside",OBJ_LABEL,0,0,0);
      ObjectSetInteger(0,"Object Inside",OBJPROP_XDISTANCE,20);
      ObjectSetInteger(0,"Object Inside",OBJPROP_YDISTANCE,40);
      ObjectSetString(0,"Object Inside",OBJPROP_TEXT,"Inside");
     }
//---
   return(INIT_SUCCEEDED);
  }

[Max Enrik]

Cool!

Look my screenshot, please.

Thanks a lot for your time Mr. Marco

[Max Enrik]

I never mind that part of code will give me different result in Indicator. : /
I try that part of code in my Indicator File.

( I decided that I will write some code in indicator files just not in my Trade Panel file. )

2nd time edited

I already use your method - now it works without any issues, hope it will work.

Thanks a lot Mr. Marco

#Not Monday - Closed

[Max Enrik]

#Refresh - Open

Once I solve my this issue - my indicator works good in my main MT4 platform - but I use 2nd MT4 platform which is my indicator needs refresh when I start MT4 platform.
I have no idea where that problem comes from... that I ask something exactly about that.

Q:  Can anyone let me something about this weird situation, please?

Thanks in advance.

[Marco vd Heijden]

You mean you witness different behavior between two platforms?

Are they the same build?

[Max Enrik]

Marco vd Heijden:

Yeah absolutely different behavior...

Also yes both of them 1065 Build

[Max Enrik]

Maybe I found where comes those weird issues...

What a secret of load template?
There is mystical things, which is destroying me at all... that is really really making me mad at all... - I have already did huge things for my EA's and Indicator's that I never spent a lot of time like I am spending few minor issues...

How? Simple!

After I decided that I should not put some scripts in my EA's files - then I continuously facing minors issues that I can't find solution in SEO. ( actually sometimes I find easily solution to my huge EA's issues on SEO - but this minor issues. )

---

I put this simple code in my example indicator file.

int OnInit()
{
  Print( "This Year", Year() );
  return(INIT_SUCCEEDED);
}

When I try to load this example file to my chart. It does not work correctly until I change TimeFrame.
( it's possible I already tired today )
( also I know I can solve this issue if I put that code in OnCalculate(...) - but I just need to put that code in OnInit() )

Please, I just need more clearly explanation for this issue. I really need it, because few my indicators have same irrelevant issues. ( that if I put this in my EA's files it will work correctly )

Thanks in advance.
Have a nice weekend.
