ObjectCreate OBJ_TREND

New comment
 

Questions about that were asked quiet oftenly and I read all answers and some article fitting to that topic - and I still cannot solve that simple problem :/

PLEASE HELP ME!

I want to draw a trendline using

ObjectCreate("Trendline",OBJ_TREND,0,Price1,Time1,Price2,Time2);

I want Price1, Time1 to take the values of bar 10 and Time2,Price2 to take the values of bar 0. I tried so many different ways and none did work, I must ask for help and I hope there is someone who nows how that can work.


Thank you very much in advance!

 
Paste code.
 

Here compile as Script. It's an old function of mine.

void start(){
    Trend_Line(Time[10],Time[0],Open[10],Open[0],Gold,STYLE_SOLID);
}

void Trend_Line(
    datetime x1, datetime x2, double y1, 
    double y2, color lineColor, double style){
    //~~~~~~~~~~
    string label = "_Trend_Line_";
    ObjectDelete(label);
    ObjectCreate(label, OBJ_TREND, 0, x1, y1, x2, y2, 0, 0);
    ObjectSet(label, OBJPROP_RAY, 0);
    ObjectSet(label, OBJPROP_COLOR, lineColor);
    ObjectSet(label, OBJPROP_STYLE, style);
    //~~~~~~~~~~
}

Hi ubzen, Hi WHRoeder,

thank you for youre answers. I checked https://www.mql5.com/en/forum/134129 already, but I was not able to make it with it, thank you anyway!

Here is the code (part of an EA) that shall draw a trendline:


   datetime    T1,
               T2;
   double      P1,
               P2;
int start()
  {

   P1 = Open[1];
   T1 = Time[1];
  
   P2 = Open[10];
   T2 = Time[10];
   
   ObjectCreate("label", OBJ_TREND, 0, T1, P1, T2, P2);
   ObjectSet("label", OBJPROP_RAY, 0);
   ObjectSet("label", OBJPROP_COLOR, Gold);
   ObjectSet("label", OBJPROP_STYLE, STYLE_SOLID);
 
  return(0);
  }
 

T1,T2,P1,P2 have values, but the EA does not draw anything. Something must be wrong.

 
In my example T1 is bar 10. Try switching them around.

Following Steps are part of custom indicator  and not expert advisers and i have started to make use of it and thank you  as soon as i saw the steps
 

There is not a lot of information on this, I am trying to learn the basics of drawing a trendline.

Each I run this code I get a horizontal green line. Any ideas what is wrong with the code.

Thank you

You are using the same price 3 times .
Additionally (beyond the horizontal line) how are you certain the dates correspond to these prices
