Help with code (Zone Shading)

[tommyjames]

Hello,

I hacked together this indicator (not knowing what I am doing). I almost have it plotting the way I want it but I am missing one part that I can't figure out. I am trying to get it to shade both zones ( 2-3 std above and below an ema). See attached. I can only get the top zone shaded. Can anyone shed some light on how to shade the bottom zone?

Thanks for the help,

Tommy

Please disregard the Plot override method. Use DrawRegion() method available in NinjaTrader 6.5.

[tommyjames]

Thanks for the reply. Do you know if there is any example code of how it would be done? I don't know much about programming, I just pasted a bunch of code together and kept tweaking it until it compiled and displayed correctly .

Thanks

Please see the Reference Samples section in the forums: http://www.ninjatrader-support.com/v...ead.php?t=4331

Thanks for the info. I have it working with "DrawRegion"

In the example script the color settings and opacity settings are hard coded. Is it possible to make them user definable?

[NinjaTrader_Josh]

You can do that just like how you would do any other variable. Please see other indicators like the SMA on how to get user definable variables.

I have another question. I have the indicator working except every time I close and reopen NT the DrawRegion color defaults back to the default even though I changed it on the chart. I guess I missed something but i'm not sure what. Any ideas?


#region Variables
private int period = 34;
private Color FillColor = Color.Blue;
private Color XMAColor = Color.Transparent;
#endregion



DrawRegion("XMA Zone", CurrentBar, 0, EMA( High, Period ), EMA( Low, Period ), XMAColor, FillColor, 2);



Thanks

Is it possible to set 'Right side margin' to a high number (e.g., 40) and draw items in the space between the last price bar and the right side of the chart (e.g., DrawRectangle)?

[NinjaTrader_Josh]

tommyjames: The colors will be the defaults every time you use the indicator again. If you want different default colors, change it in the Variable section.

spenbm01: You currently cannot programmatically draw in the right hand region, but you can do it manually through the chart draw tools.

[tommyjames]

Yes I understand that they will be defaults when I add the indicator to a chart but the colors default back on an existing chart with the indicator already on it. It is the only indicator that does this, so there must be something missing in the code.

Thanks

I didn't notice anything off the bat. If you could post the indicator I can take a quick look for you to see if there truly isn't anything out of place.

Here is the indicator....

tommyjames,

Try serializing your color parameter.

After your XMA Color in the "Properties" section add this

[Browsable(false)]
public string XMAColorSerialize
{
    get { return NinjaTrader.Gui.Design.SerializableColor.ToString(XMAColor); }
    set { XMAColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
}

[tommyjames]

Thanks for the reply. I put the code in but it still behaves the same.....

Is this a new section or is it in place of the existing section?

Any more ideas?

Thanks

[NinjaTrader_Josh]

Try adding one for the FillColor also.

These should be new sections in the Properties region of your code.

That region should look like this:

        /// <summary>
        /// </summary>
        [XmlIgnore()]
        [Description("Zone Color")]
        [Category("Colors")]
        [Gui.Design.DisplayNameAttribute("Zone Color")]
        public Color fillColor
        {
            get { return FillColor; }
            set { FillColor = value; }
        }
        
        [Browsable(false)]
        public string FillColorSerialize
        {
            get { return NinjaTrader.Gui.Design.SerializableColor.ToString(FillColor); }
            set { FillColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
        }
        
        /// <summary>
        /// </summary>
        [XmlIgnore()]
        [Description("XMA Color")]
        [Category("Colors")]
        [Gui.Design.DisplayNameAttribute("XMA Color")]
        public Color xMAColor
        {
            get { return XMAColor; }
            set { XMAColor = value; }
        }
        
        [Browsable(false)]
        public string XMAColorSerialize
        {
            get { return NinjaTrader.Gui.Design.SerializableColor.ToString(XMAColor); }
            set { XMAColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
        }
        
        /// <summary>
        /// </summary>
        [Description("Numbers of bars used for calculations")]
        [Category("Parameters")]
        public int Period
        {
            get { return period; }
            set { period = Math.Max(1, value); }
        }
