Question about RSI and Candlestick Range

[Pablo GJ]

Hi!

I'm trying to make an indicator, it's like a WMA but i'm trying to give more weight to those candlesticks with the farthest RSI 50...

I know it's a bit strange....

Thank you!

Pablo,

Do you have a calculation method or example that you can share to help with this?

[Pablo GJ]

Now I'm trying to put the RSI indicator with bars and I have a problem with the code that i don't understand...

public class RSIBARS : Indicator
{
#region Variables
private DataSeries avgUp;
private DataSeries avgDown;
private DataSeries down;
private int period = 14;
private int smooth = 3;
private DataSeries up;
#endregion

/// <summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
/// </summary>
protected override void Initialize()
{
Add(new Plot(Color.Green,PlotStyle.Bar, "RSI"));
Add(new Plot(Color.Orange, PlotStyle.Bar, "Avg"));

Add(new Line(System.Drawing.Color.DarkViolet, 30, "Lower"));
Add(new Line(System.Drawing.Color.YellowGreen, 70, "Upper"));

avgUp = new DataSeries(this);
avgDown = new DataSeries(this);
down = new DataSeries(this);
up = new DataSeries(this);

The problem is in the 23 line

The rest of the code it's exactly the same as the RSI of the ninja trader

Pablo,

Which one is line 23?

What is the problem that you are having?

[Pablo GJ]

private DataSeries avgUp

the program doesn't tell me wich error is

Could you please attach the whole cs file for us to give it a run? Thanks,

Pablo,

I'm not receiving a compile error for the script.

Can you please explain more into what kind of error you are running into?

Where do you see this error and when?

[Pablo GJ]

Is another way to insert an image that is only in my pc without a URL?

Another question... do you know how can i relate a candlestick with other values like Volume price or RSI
to make a WMA choosing the highest values first and leaving last the lowest... for example if i'm making a WMA with 21 periods, I want to take first the candlestick with the highest range.

thank you again for all

[NinjaTrader_PatrickH]

Hello Pablo GJ,

Thank you for your patience.

To add an image from your PC you will need to override the Plot() method and then use the DrawImage() method with Image.FromFile() for example:

		public override void Plot(Graphics graphics, Rectangle bounds, double min, double max)
		{
			graphics.DrawImage(Image.FromFile(@"C:\Users\yourUserNameForWindows\Desktop\imageName.jpg"),bounds.X, bounds.Y, bounds.Width, bounds.Height);
		}

For information on overriding the plot take a look at the CustomPlotSample under Tools > Edit NinjaScript > Indicator > CustomPlotSample.

For DrawImage please visit the following link: http://msdn.microsoft.com/en-us/libr...v=vs.110).aspx

For your second item, can you provide further details on what you by "I want to take first the candlestick with the highest range"?
Are you referring to the highest volume bar within that 21 period?

[Pablo GJ]

Ok I will try that for the image!
I will also try to make better that question... i'm not english and it's a bit difficult for me to express some things about this...

Thank you again for your help i'm very grateful!!
