Hi
I cannot display both the high and low daily lines with the next code
Please help
Thanks

void Dayly_High_Low_Lines()
  {
   double Low_price=iLow(Symbol(),PERIOD_D1,0);
   ObjectCreate(0,Symbol(),OBJ_HLINE,0,0,Low_price);
   ObjectSet(Symbol(),OBJPROP_COLOR,clrRed);        // changing the color of the lower line
   ObjectSet(Symbol(),OBJPROP_WIDTH,2);             // now the lower line will be dashed

 
   
   double High_price=iHigh(Symbol(),PERIOD_D1,0);
   ObjectCreate(0,Symbol(),OBJ_HLINE,0,0,High_price);
   ObjectSet(Symbol(),OBJPROP_COLOR,clrGreen);     // changing the color of the Higher line
   ObjectSet(Symbol(),OBJPROP_WIDTH,2);            // now the Higher line will be dashed
   
 
    Alert("The Daily Low  price is: " + DoubleToStr(Low_price, Digits));
    Alert("The Daily High price is: " + DoubleToStr(High_price, Digits));
 }

 

Please edit your post (don't create a new post) and replace your code properly (with "</>" or Alt-S), or attach the original file directly with the "+ Attach file" button below the text box.

NB! Very important! DO NOT create a new post. EDIT your original post.

You are giving the same "name" to both objects, using the symbol name as the name of the objects.

Please use distinct names for each object (and not just the symbol name) — Documentation on MQL5: Object Functions / ObjectCreate

You still haven't edited your original post to insert your code with the </> tool.

Hi,

I would like to create a dashboard with 28 rows and 14 columns using classes. However, I am having trouble with the 12th and 13th columns as they are not displaying correctly on the chart (please refer to the attached photo). I would greatly appreciate your help in resolving this issue.

Thank you.

You can debug the code as follows: You set break points inside the nested for loops which create the little squares. Then click "debug with historical data".

Now that you can go through the whole construction step by step, you can right click on variables like panelwidth and panelheight to put them under observation. Then watch them how they change values during the whole process.

Also take the create function's return value into a boolean variable and observe that to see if the creation was true or false.
