    help with DrawRay function

    Hello,

    Can someonone help on the following code?

    protected override void OnBarUpdate()
    {
    // Use this method for calculating your indicator values. Assign a value to each
    // plot below by replacing 'Close[0]' with your own formula.
    // Plot0.Set(Close[0]);

    if (CurrentBar > 1) DrawRay("ray", 1, Open[0], 0, Open[0], Color.LimeGreen);

    //this.DrawRectangle("Rec", false, 0, High[0], -10, Open[0], Color.Blue, Color.Blue, 3);
    //RemoveDrawObject("tag1");
    }
    This indicator works but does not display the Price. I would like it to display the price on the Price Panel or as a text above the Line

    Thanks

    Hello KenyaTrader,

    Thank you for your post and welcome to the forums!

    When you say not displaying the price are you referring the plot? or the DrawRay()?

        Hello kenyaTrader,

        You will need to uncomment the Plot0.Set(Close[0]);, so remove the '//' in front of the Plot0.Set().

          Sorry for the confusion. This is what i wanted with the below code, when the line is drawn, to have it dispaying the price on th line

          protected override void OnBarUpdate()

          if (CurrentBar > 1) DrawLine ("Open", -20, Open[0], 0, Open[0], Color.Blue);
          DrawLine("Open2", -20, Open[0] - 3 * TickSize, 0, Open[0] - 3 * TickSize, Color.Red);
          DrawLine("Open3", -20, Open[0] + 3 * TickSize, 0, Open[0] + 3 * TickSize, Color.Red);

          Or there might be another way to achieve my goal

          Thanks...

                Hello kenyaTrader,

                Thank you for your response and thank you to koganam for that post.

                strStopValue is likely a string representing the price level of the stop order in the context of that example. So likely a double that has been converted to a string to be passed to the DrawText().

                  this is my final version that works

                  thanks koganam + NinjaTrader_PatrickH for helping me

                  protected override void OnBarUpdate()
                  {
                  double myOpen = Open[0] ;
                  double myOpen1 = Open[0] - 3 * TickSize;
                  double myOpen2 = Open[0] + 3 * TickSize;

                  if (CurrentBar > 1) DrawLine ("Open", -17, Open[0], 0, Open[0], Color.Blue);
                  DrawText("Text", true, myOpen.ToString(), -20, Open[0], 0, Color.Black, new Font("Times New Roman", 12), StringAlignment.Center, Color.Blue, Color.Gray, 100);

                  DrawLine ("Open1", -20, Open[0] - 3 * TickSize, 0, Open[0] - 3 * TickSize, Color.Red);
                  DrawText("Text1", true, myOpen1.ToString(), -20, Open[0] - 3 * TickSize, 0, Color.Black, new Font("Times New Roman", 12), StringAlignment.Center, Color.Blue, Color.Gray, 100);

                  DrawLine ("Open2", -20, Open[0] + 3 * TickSize, 0, Open[0] + 3 * TickSize, Color.Red);
                  DrawText("Text2", true, myOpen2.ToString(), -20, Open[0] + 3 * TickSize, 0, Color.Black, new Font("Times New Roman", 12), StringAlignment.Center, Color.Blue, Color.Gray, 100);

                  }

                    }
                    You are creating 3 copies of the same font object per run, and not disposing of the objects. You would be better off creating one copy of the font object, using it 3 times, then disposing of it.
