Adding Pivots to the Pivot Indicator

[sgordet]

As I'm a novice at C, I try to build on the existing Ninja scripts.
I took the "Pivots" script and changed the values to use it for creating Fibonacci horizontal lines. That worked fine.
Now I'm trying to add two additional lines. I've tried both extended lines and internal lines. The script compiles without errors but now no lines show up.
If you could take a look at the script and point me in the right direction, I would be very appreciative.

sgordet,

Can you please clarify exactly where in your code you have added these lines? Can you post a snippet of the signature you are using?

When you apply this indicator to a chart, do you get any errors on the Log tab of the Control Center? If so, what do these errors report?

Thanks, Matt.
I found the error message in the log:
Error on plotting indicator. Check the OnBarUpdate or the "Plot" method. Index was outside the bounds of the array.

Changes I made:
Added two variables for the lines and defined them..
Added two plots.
Added two set statements.
Added the two dataseries in Properties.

I don't understand what the "signature" is or I would post a snipped of it as requested.

It sounds from the error message that the problem is that I didn't expand the array that holds the added lines, but I can't find where it's declared.

Hello,

Can you post the plots that you added?

All of the code is the same as the original Pivots indicator except for the formulas for arriving at each of the pivots, which works fine as long as I don't add any new pivots

These are all of the new code lines. They were added directly after each of the R3 and S3 statements:

Variables
privatedouble s4 = 0;
privatedouble s4 = 0;

Initialize
Add(new Plot(new Pen (Color.Blue,2), "R4"));
Add(new Plot(new Pen (Color.Red,2), "S4"));

OnBarUpdate
s4 = pp - (currentHigh - currentLow) * .8;
r4 = pp + (currentHigh - currentLow)* .8;

R4.Set(r4);
S4.Set(s4);

[Browsable(false)]
[XmlIgnore]
public DataSeries R4
{
get { return Values[7]; }
}

[Browsable(false)]
[XmlIgnore]
public DataSeries S4
{
get { return Values[8]; }

That indicator uses a custom Plot override, so you need to make sure that you are providing the correct input to the Plot() method. In this case, you must have as many brushes are there are lines, so you need to add the correct number of brushes to the brushes collection/array.

Add the correct number of brushes to this line thus:

		private	SolidBrush[]		brushes				= { new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black), new SolidBrush(Color.Black)};

I added 2 brushes.

Thanks a million, Koganam. That did it!
