VOLColor modifications

[blaircampbell]

Hi all,

I want to take VOLColor indicator and modify it to do the following.



Add neutral volume so either open close same bar are equal or off by one tick then the plot would be say black

Calculate and plot the moving average of all up volume and down volume

I have done web programing... so have some experience but can anyone help me get started on making these changes?

regards,

Blair

Blair,

I suggest you start with the custom indicators tutorial so you get an idea of the different code blocks and what they do. http://www.ninjatrader-support.com/H...tml?Overview23

Then you will need to create an additional plot for neutral volume. For doing a moving average, you will need to create plots for those too and create your MA logic to run off of whichever information you want.

so far

Here is my code so far

I am not sure what the get { return Values[1]; } does

protected override void Initialize()
{
Add(new Plot(new Pen(Color.Red, 3), PlotStyle.Bar, "Volume Down"));
Add(new Plot(new Pen(Color.Navy, 3), PlotStyle.Bar, "Volume Up"));
Add(new Plot(new Pen(Color.Black, 3), PlotStyle.Bar, "Volume Neutral"));
Add(new Line(Color.DarkGray, 0, "Zero line"));
}

protected override void OnBarUpdate()
{
if(Open[0]>Close[0])
VOLDown.Set(Volume[0]);
else if (Open[0]<Close[0])
VOLUp.Set(Volume[0]);
else if (Open[0]==Close[0])
VOLNeutral.Set(Volume[0]);

}

silly me

I changed the

get { return Values[1]; }

to

get { return Values[2]; }

and now I am at stage one it works and plots neutral volume as a black bar

[NinjaTrader_JoshP]

Each plot needs its own Values[] index. Values[0] is for the first plot. Values[1] is second. Values[2] is third. As you have made a new plot you need to use a new [] index for that plot.

got it

I answered my own question and thanks for your help

now I need to add some moving average

and the one that might be harder is to show vol bar black that is not == but off by one tick of ==

[NinjaTrader_JoshP]

To do one tick off just do + 1 * TickSize.

if (Close[0] == Open[0] + 1 * TickSize)

If you want a range.

if (Close[0] >= Open[0] || Close[0] <= Open[0] + 3 * TickSize)

indicator for post

I have modified the volume indicator to show up down and now neutral volume

Not sure if this is the proper way to make it available or not?
