How to read object value

[Cromo]

Hi,

I want to read Trend line value (price)

Below Trend line Name has some time value(time stamp).

But I want to ignore the time stamp and just want to read the 2nd value.

How can I read the Object price2?

  double price2 = ObjectGet( "LINE12", OBJPROP_PRICE2 );

Use ObjectGetDouble  to read the anchor points

void OnReadObj()
  {
//---
   int     total; 
  string obj_name; 
  double obj_PriceStart=0;
  double obj_PriceEnd=0;
  
  
     total=ObjectsTotal();
     for(int i=0;i<total;i++)
       {
       obj_name=ObjectName(i);
        if(ObjectType( obj_name)==OBJ_TREND)
        {
         
        obj_PriceStart=NormalizeDouble(ObjectGet(obj_name, OBJPROP_PRICE1),Digits);
        obj_PriceEnd=NormalizeDouble(ObjectGet(obj_name, OBJPROP_PRICE2),Digits);
        
        Print("Obj Name ",obj_name," Start Price=",obj_PriceStart," End Price=",obj_PriceEnd);
        
         
        }

     double price = ObjectSetDouble(ChartID(), "LINE12-***", OBJPROP_PRICE, 0);

 Can I use ****  after LINE12- ?

@ Cromo

Bastem, thanks.

But if I scan all object, how can I get the newest object price?

because there are many same kind of objects on the chart.
