unlock line object?

[e-man]

is there a way to unlock a line that can be moved around by mouse-click?

found this link:

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?idrawobject.htm

this code doesn't seem to be working:

        protected override void Initialize()
        {
            ...
            Add(new Line(Color.Blue, 10, "myLine"));
            ...
        }

        protected override void OnBarUpdate()
        {
            ...
            foreach (IDrawObject draw in DrawObjects)
            {
                if (draw.DrawType == DrawType.Line)
                    draw.Locked = false;
            }
            ...
        }

cheers,

Hello,

Thank you for your forum post.

I copy and pasted your code into my NinjaTrader 7 and it executed for me without any issues and unlocked the line I drew on the chart. Are you using NinjaTrader 7 Beta 16 this is located in the control center->help->about to the right of the NinjaTrader logo. Also if you have calculate on bar close set to true for this indicator it will unlock all drawn objects every bar close.

Also make sure that you are drawing a line and not an extended line or anything like that.

Let me know if I can be of further assistance.

Hi Brett,

thanks for the reply. yes, i'm using NT7b16 and have CalculateOnBarClose=true.

this indicator plots in panel2 (eg. open up RSI or MACD and add the code). for whatever reason, it's not letting me select the line to move. do you think it has to do with panel2?

also, is there a way to declare the line as undocked? i didn't see an overload with that option. ideally, i would like to initialize the line and just set the property as undocked, rather than calling this code on every OnBarUpdate().

cheers,

Hello e-Man,

That help guide section for draw objects applies to objects placed with Draw commands. Lines added using Add (new Line as you have can't be manipulated in the same way.

You can DrawHorizontalLine() and adjust it with your mouse once it's drawn.

DrawHorizontalLine("myLine", 10, Color.Blue) ;

excellent! thanks for your help ... that did the trick.

in case anyone else needs the full code, here 'tis:

        protected override void OnBarUpdate()
         {
           ...
           if (CurrentBar == 0)
           {
             // draw line
             DrawHorizontalLine("myBand", false, 10, Color.Blue, DashStyle.Solid, 1);
        
             // unlock line
             foreach (IDrawObject draw in DrawObjects)
             {
               if (draw.DrawType == DrawType.HorizontalLine)
                 draw.Locked = false;
             }
             ...
           }
         }

also, if the lines are in a secondary panel (eg. if you're drawing lines on an osciallator like RSI or histogram like MACD), use DrawOnPricePanel in Initialize() like this:

        protected override void Initialize()
        {
            ...
            DrawOnPricePanel = false;
            ...
        }

cheers,
