    Hopefully someone from NinjaTrader might have more info as well.
    I got it based on the reading you suggested. Thank you very much!

    For Q3, I want to draw a horizontal line on chart, call it key_Reversal, and make my script read that price value.

    Your solution makes sense if the line is drawn by the same script, as shown on its property "is attached to" the script name.

    But manually drawn objects are attached to something identified by instrument + chart type, such as "ES 9-20 2000 tick"

    I am trying to find for a way for the script to read a manual drawing, if that's possible.

    Q1: You can use Draw.TextFixed() to at least get it in the corner of the chart, or make some custom code in OnRender for extra precise positioning directly beside the indicator name if necessary, but that will take more work and cause complications as other indicators get added to the chart. Example:
    Code:
    SimpleFont simpleFont = new SimpleFont("Arial",14);
    Draw.TextFixed(this,"Variable 1", Variable1.ToString(), TextPosition.TopLeft, Brushes.White, simpleFont, Brushes.White, Brushes.Black, 0);
    Q2: I don't know how to do this so I won't try to answer.

    Q3: Not sure if I understand your question correctly, but you can do something like this:
    Code:
    HorizontalLine horizontalLine = Draw.HorizontalLine(this,"HorizontalLine",700,Brushes.Red);
    double LineValue = horizontalLine.Anchors.ElementAt(0).Price;
    Although there is probably a simpler way.

    EDIT: I misunderstood your question for Q3. I think you meant using a line that you MANUALLY drew on the chart - in which case, you can loop through the DrawingObjects on the chart and find a particular line. Check out this guide: https://ninjatrader.com/support/help...rawobjects.htm

  • Several questions on indicator-indicator, and indicator-chart interactions

    Q1.display input parameters on chart

    I set up an input with:

    [Display(ResourceType = typeof(double), Name = "day Max Loss", GroupName = "NinjaScriptParameters", Order = 6)] public double input_dayMaxLoss { get; set; }

    Is there away for the input value to show on the top left of the chart, where the indicator name is?


    Q2.access script 1 input from script 2

    With the same input as above, is there away to access it from another script?

    For example, I have 2 scripts, one long one short. Now I need to put in max loss value for them individually. Is it possible for them to follow a single input of the dayMaxLoss variable?

    Q3.make script read drawings on chart

    After I draw a horizontal line on the chart, is it possible to make the script read that vertical value, for purposes such as setting a stop loss at that location?

    Thanks a bunch!
