query name value of arrow

New comment
 

Hi,

i want to find Text value of arrow in my chart.

i was checked ObjectFind, ObjectGet but it seems to be don't have function to query Text value of arrow .

what kind of method or function should have to use to query name value in Arrow?

thanks!

 
so in this image, i want to query "Test" value..

"Text" is the name, most Object functions use the name . . . if you have only one arrow Object you can use ObjectName() to get it's name in a loop where you loop through the Objects and select by ObjectType() where the type is an arrow.
  
   for (int i = NeedBarsCounted; i >= 1; i--)
   {
      if (i == Bars - 1) continue;
          string name = ObjectName(i);
    if (StringFind(name, "Test") == 0)
   {      
         Alert("found");
         ctime = Time[0];
         if (ctime == prevtime) { return(0); } 
         prevtime = ctime;
    }
    }

i was query successfully by use ObjectName and StringFind but one of problem is after every next bar "Alert("found");" fire everytime.

in my chart,many of arrow will incoming and i want to alert only one time not duplicate alarm continue .

how can i make Alert command only one time? thanks

Remember which arrows you have already alerted for . . . before you alert next time check if you have already alerted for the arrow. If the new arrow is always a more recent date then you can remember the datetime for the last alerted arrow . . .

}




void DisplayAlert(string message, int shift)
  {

     {
       lastAlertTime = Time[shift];
       Alert(message, Symbol(), " , ", Period(), " minutes chart");
     }
  }
  
  
void doAlert(int forBar, string doWhat)
{
   static string   previousAlert="nothing";
   static datetime previousTime;
   string message;
   
   if (previousAlert != doWhat || previousTime != Time[forBar]) {
       previousAlert  = doWhat;
       previousTime   = Time[forBar];

       //

       message =  Symbol()+" at "+TimeToStr(TimeLocal(),TIME_SECONDS)+" "+doWhat;
       
          if (alertsMessage) Alert(message);
          if (alertsEmail)   SendMail(Symbol()+"alerts",message);
          if (alertsSound)   PlaySound("alert2.wav");
         
   }
   
}

this is what i modified but it not working, still alert message popup continue.

what is wrong in here? it really confuse

 

First of all, I removed the code that is not used by the program to make it easier to follow

#property indicator_chart_window




static datetime lastAlertTime;

//
//------------------------------------------------------------------

int init()   { 
   
return(0); 
}
int deinit() { 
 
return(0); }


int start()
{
  

   int    counted_bars=IndicatorCounted();
   int i,shift;
   int limit;
   if(counted_bars < 0)
   return(-1);
   if(counted_bars > 0)
   counted_bars--;
   limit = Bars - counted_bars;
   for(i = shift ;i<=limit;i++)
    {
    string name = ObjectName(i);
    if (StringFind(name, "Test") == 0) 
    {
    DisplayAlert("Found!",Symbol());
         
    Print(Symbol());
    }

}

}




void DisplayAlert(string message, int shift)
  {
   if(shift <= 2 && Time[shift] != lastAlertTime)
     {
       lastAlertTime = Time[shift];
       Alert(message, Symbol(), " , ", Period(), " minutes chart");
     }
  }
  
  

  

Now, it may just be my lack of knowledge, but I don't understand the function call

 DisplayAlert("Found!",Symbol());

that sends 2 strings when the function is expecting a string and an integer

void DisplayAlert(string message, int shift)
 

thanks! i was test your modified source but still no alert for incoming arrow.

any hint for code much appreciate!

Try this . . .

#property indicator_chart_window


static datetime lastAlertTime;

//
//------------------------------------------------------------------

int init()   
   { 
   return(0); 
   }

int deinit() 
   { 
   return(0); 
   }


int start()
   {
   int ObjectIndex, shift;
   int limit;
   string ObjName;
   datetime ArrowObjTime;
   
   for(ObjectIndex = ObjectsTotal() - 1 ; ObjectIndex >= 0; ObjectIndex--)
      {
      if(ObjectType( ObjectName(ObjectIndex) ) == OBJ_ARROW) 
         ObjName = ObjectName(ObjectIndex);

      // find the most recent Arrow Object
      if(ObjectGet(ObjName, OBJPROP_TIME1) > ArrowObjTime)   //  this arrow is more recent
         ArrowObjTime = ObjectGet(ObjName, OBJPROP_TIME1);

      
      }


      if (lastAlertTime < ArrowObjTime) 
         {
         DisplayAlert("Found!");
         
         Print(Symbol());
         lastAlertTime = ArrowObjTime;
         }

   return(0);
   }




void DisplayAlert(string message)
   {
   Alert(message, " ", Symbol(), " , ", Period(), " minutes chart");
   }
 

thanks! this is great guide for me!

now i was modified bit and it working almost well.

but one of problem is incoming Name field's value is changing almost everytime.

for exmaple,

varTest;test23662;

varTest;test221;

varTest34223;test2;

varTest1;test33;

i want to extract rear value so what i want to extract value will be

test23662

test221

test2

test33

problem is it some hard to extract those info by use mt4 function.

i can't found proper String manipulatoin method.

please help me!

thanks !
