Histogram in Windows forms

[GKonheiser]

hi,

what is the best way to display a histogram in NT 7. I was thinking of using using System.Windows.Forms.DataVisualization.Charting; but am I correct in thinking that this is not an option? What would be the alternatives?


Thanks

Hello,

Thank you for contacting us regarding your inquiry.


In order to add a histogram, you first would have to put the data in the form of an indicator. If you don't have this accomplished yet, or an indicator doesn't already exist, you could use the indicator wizard to do so.


I have included a link that reviews plot statements in indicators:

• http://ninjatrader.com/support/helpGuides/nt7/entering_calculation_logic6.htm

Within the indicator you would use a Plot statement. Lets use the standard MACD for example:

 
 
 [FONT=Courier New][FONT=Courier New]Add([/FONT][/FONT][COLOR=#0000FF][FONT=Courier New][COLOR=#0000FF][FONT=Courier New][COLOR=#0000FF][FONT=Courier New]new[/FONT][/COLOR][/FONT][/COLOR][/FONT][/COLOR][FONT=Courier New][FONT=Courier New] Plot([/FONT][/FONT][COLOR=#0000FF][FONT=Courier New][COLOR=#0000FF][FONT=Courier New][COLOR=#0000FF][FONT=Courier New]new[/FONT][/COLOR][/FONT][/COLOR][/FONT][/COLOR][FONT=Courier New][FONT=Courier New] Pen(Color.Navy, [/FONT][/FONT][COLOR=#800080][FONT=Courier New][COLOR=#800080][FONT=Courier New][COLOR=#800080][FONT=Courier New]2[/FONT][/COLOR][/FONT][/COLOR][/FONT][/COLOR][FONT=Courier New][FONT=Courier New]), PlotStyle.Bar, [/FONT][/FONT][COLOR=#800000][FONT=Courier New][COLOR=#800000][FONT=Courier New][COLOR=#800000][FONT=Courier New]"Diff"[/FONT][/COLOR][/FONT][/COLOR][/FONT][/COLOR][FONT=Courier New][FONT=Courier New]));[/FONT][/FONT]
 [FONT=Courier New][FONT=Courier New][/FONT][/FONT][FONT=Courier New][FONT=Courier New]

Hi Matt,

OK so I dont need to program a custom windows form which is great.

What im trying to do is plot the difference of the close and SMA of the close for the last 500 ticks, so,

Close[0] -  SMA(Close[0], 500) 
Close[1] -  SMA(Close[0], 500) 
Close[2] -  SMA(Close[0], 500) 
.
.
.
Close[500] - SMA(Close[0], 500)

The question is how would I achieve this . in a loop maybe,

for( i = 0; i < 500; i++)
{
     // Calculate value
     value = Close[i] - SMA(Close[0])

     // Print value on histogram
     // how would i achieve this?
}

Hello,

I have provided the code that you will need to complete your histogram. You wont need a for loop, as the OnBarUpdate() method will continually calculate each bar.

(------- lines designate each different area of code to make changes... don't include them, etc)

#region Variables
privatedouble difference = 0;
#endregion

----------------------------------


protectedoverridevoid Initialize()

{

Overlay = false;

Add(new Plot(new Pen(Color.Navy, 2), PlotStyle.Bar, "Diff"));

Add(new Line(Color.DarkGray, 0, "Zero line"));

}
-------------------------------------------

protectedoverridevoid OnBarUpdate()
{
difference = Close[0]- SMA(Close,500)[0];
Values[0].Set(difference);
}
