How to get x and y from Hline? - page 2

Kok Hoong Cheang:

I have done that; I can retrieve y and set the starting position of the label; thank you.

But if I were to move the HLine, the label will not move with it again; could you take a look at my code?

No, I will not take a look at your code.

You are still trying to get the time from a horizontal line.

ChartTimePriceToXY(0,0,(datetime)ObjectGetInteger(0,"Entry",OBJPROP_TIME),ObjectGetDouble(0,"Entry",OBJPROP_PRICE),x1,y1);

Re-write your code using TimeCurrent() and then I will take a look at any problems you may be having.

 

Try ObjectMove() in stead of OBJPROP_YDISTANCE

Here is an example:

//+------------------------------------------------------------------+ 
//| Move horizontal line                                             | 
//+------------------------------------------------------------------+ 
bool HLineMove(const long   chart_ID=0,   // chart's ID 
               const string name="HLine", // line name 
               double       price=0)      // line price 
  { 
//--- if the line price is not set, move it to the current Bid price level 
   if(!price) 
      price=SymbolInfoDouble(Symbol(),SYMBOL_BID); 
//--- reset the error value 
   ResetLastError(); 
//--- move a horizontal line 
   if(!ObjectMove(chart_ID,name,0,0,price)) 
     { 
      Print(__FUNCTION__, 
            ": failed to move the horizontal line! Error code = ",GetLastError()); 
      return(false); 
     } 
//--- successful execution 
   return(true); 
  } 
//+------------------------------------------------------------------+

Can't use move, because it's a label not a text object.

Ah ok sorry.

//+------------------------------------------------------------------+
//| Move the text label                                              |
//+------------------------------------------------------------------+
bool LabelMove(const long   chart_ID=0,   // chart's ID
               const string name="Label", // label name
               const int    x=0,          // X coordinate
               const int    y=0)          // Y coordinate
  {
//--- reset the error value
   ResetLastError();
//--- move the text label
   if(!ObjectSetInteger(chart_ID,name,OBJPROP_XDISTANCE,x))
     {
      Print(__FUNCTION__,
            ": failed to move X coordinate of the label! Error code = ",GetLastError());
      return(false);
     }
   if(!ObjectSetInteger(chart_ID,name,OBJPROP_YDISTANCE,y))
     {
      Print(__FUNCTION__,
            ": failed to move Y coordinate of the label! Error code = ",GetLastError());
      return(false);
     }
//--- successful execution
   return(true);
  }
//+------------------------------------------------------------------+

If you want it to scroll with the chart you can also use:

//+------------------------------------------------------------------+
//| Creating Text object                                             |
//+------------------------------------------------------------------+
bool TextCreate(const long              chart_ID=0,               // chart's ID
                const string            name="Text",              // object name
                const int               sub_window=0,             // subwindow index
                datetime                time=0,                   // anchor point time
                double                  price=0,                  // anchor point price
                const string            text="Text",              // the text itself
                const string            font="Arial",             // font
                const int               font_size=10,             // font size
                const color             clr=clrRed,               // color
                const double            angle=0.0,                // text slope
                const ENUM_ANCHOR_POINT anchor=ANCHOR_LEFT_UPPER, // anchor type
                const bool              back=false,               // in the background
                const bool              selection=false,          // highlight to move
                const bool              hidden=true,              // hidden in the object list
                const long              z_order=0)                // priority for mouse click
  {
//--- set anchor point coordinates if they are not set
   ChangeTextEmptyPoint(time,price);
//--- reset the error value
   ResetLastError();
//--- create Text object
   if(!ObjectCreate(chart_ID,name,OBJ_TEXT,sub_window,time,price))
     {
      Print(__FUNCTION__,
            ": failed to create \"Text\" object! Error code = ",GetLastError());
      return(false);
     }
//--- set the text
   ObjectSetString(chart_ID,name,OBJPROP_TEXT,text);
//--- set text font
   ObjectSetString(chart_ID,name,OBJPROP_FONT,font);
//--- set font size
   ObjectSetInteger(chart_ID,name,OBJPROP_FONTSIZE,font_size);
//--- set the slope angle of the text
   ObjectSetDouble(chart_ID,name,OBJPROP_ANGLE,angle);
//--- set anchor type
   ObjectSetInteger(chart_ID,name,OBJPROP_ANCHOR,anchor);
//--- set color
   ObjectSetInteger(chart_ID,name,OBJPROP_COLOR,clr);
//--- display in the foreground (false) or background (true)
   ObjectSetInteger(chart_ID,name,OBJPROP_BACK,back);
//--- enable (true) or disable (false) the mode of moving the object by mouse
   ObjectSetInteger(chart_ID,name,OBJPROP_SELECTABLE,selection);
   ObjectSetInteger(chart_ID,name,OBJPROP_SELECTED,selection);
//--- hide (true) or display (false) graphical object name in the object list
   ObjectSetInteger(chart_ID,name,OBJPROP_HIDDEN,hidden);
//--- set the priority for receiving the event of a mouse click in the chart
   ObjectSetInteger(chart_ID,name,OBJPROP_ZORDER,z_order);
//--- successful execution
   return(true);
  }
//+------------------------------------------------------------------+

With that ObjectMove example.
