Thanks a lot buddy. We'll Do.

Okay, this doesn't make sense, sometimes it works, other times I keep getting this error.

As you can see I'm trying to to get the indicator to know which Chart it's on so it knows which FUTURES contract to use. I typed Conditional statements in the void Initialize() area, I don't know if that causes problems.

Can someone please help fix this error.

Contract "6J 06-14" comes into existence on a specific date. Before that date, as the contact does not exist, your second price DataSeries will not be created, so any reference to it will be out of the bounds of any array that references it.

You will have to make some kind of arrangement to make sure that you are referencing existing contracts. One way might be to reverse your logic, and run on the 6J contract, calling $USDJPY, as the latter is an invariant string. Other ways would be more complex, as you would have to determine the date, so that you can use the correct contract.

Nevermind Got iT!

Nevermind that last post. I got it.

 myVariable = (Instrument.FullName.ToString());

Cheers!!

Adding Instrument Type

Ok another question. How do I get the indicator to determine what Instrument it's on, so that I can use that Value and place it in a Variable or Conditional Statement.

For instance.

if InstrumentType. == USD/JPY {DO something}

something like that?

what's the actual code to do this??

[ginx10k]

It works

It works. it was just a dataseries issue. I had 3 days set to load.. thanks!! Works fine now.

[NinjaTrader_Jesse]

Hello ginx10k,

Try commenting out the following line

if (Volumes [0] [0] < Volumes [1] [0])

It looks like the Volume on index 0 is not less than the volume on index 1 so nothing is being displayed. the print statement in your image would still work though as that is not part of this if statement.

I commented that line out and everything popped back up when using the code in your image.

Please let me know if I may be of additional assistance.

Small ERROR

Hey Jesse, yea the BarsRequired solved the Plotting issue. Indicators works great on One Dataseries.

But When I tried to add 6J to the chart, without changing anything else, the Indicator Won't Load. I'm thinking it's cause adding the new Dataseries changes the Index[] value. So what change do I have to do on the Code so that the Indicator can display when more than One dataseries are present.

http://screencast.com/t/pCPlRHyhpWHl

i.e. I tried Volumes[2][0] but that didn't work. and I have NO way of finding the Actual Index value of anything?

[NinjaTrader_Jesse]

Hello ginx10k,

Please excuse my prior post and thank you koganam for clearing that up. Here is a sample of a working Volume indicator based of the index of the added series.

The reason you are getting the error is it is checking before there are bars to check. I added the code below to resolve this.

if(CurrentBar < BarsRequired)
				return;

Here is the complete code.

		protected override void Initialize ()
		{
			Add (new Plot (new Pen (Color.Red, 3), PlotStyle.Line, "VolumePlot"));
			Add ("6J 06-14", PeriodType.Minute, 5);
			Overlay = false;
		}

		protected override void OnBarUpdate ()
		{
			if (CurrentBar < BarsRequired)
				return;
			if (Volumes [0] [0] > Volumes [1] [0])
				VolumePlot.Set (Volumes [1] [0]);
			Print ("The current bar's volume price is greater");
		}

		#region Properties

		[Browsable (false)]	
		[XmlIgnore ()]		
		public DataSeries VolumePlot {
			get { return Values [0]; }
		}

		#endregion
	}
}

Please let me know if I may be of additional assistance.

Ok I think the error was that I didn't Use the " " marks. So I changed the code

        protected override void Initialize()
        {
            Add("6J 6-14", PeriodType.Minute, 5);
           
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
            //Compare Volume of current bar to 5 minute
         if (Volumes[0][0] < Volumes[1][0])
         Print("The current bar's volume price is Smaller");
        };

and it compiled successfully. However, I'm still not showing any Volume values on the Panel. And it's NOT displaying anything to the OUTput window. What am I missing.

P.S. I'm testing on Market replay with all Data available, so Data isn't the problem. just trying to figure out what I'm missing NOW. why won't it compare the Volumes or show anything. Thank you!!

Now we're talking. so for instrument, I can add 6J?? or is there other syntax. 2nd. This example is for Strategies. I know the Add() doesn't work on Indicator code.

How would I go about adding this to an indicator? Basically what would the Code look like.
Or do I need to use the VOL() call function.

Still trying to figure all this coding stuff out. reading the Help guides does help, but sometimes its more confusing.

Not quite correct. You can Add() price data series to both indicators or strategies: you cannot Add() indicators to other indicators; only to strategies.

For futures, you must add the full contract designation: not just "6J", but "6J 05-14".

Then you refer to its volume with Volumes[1][0].

I tried

 protected override void Initialize()
        {
Add(6J, PeriodType.Minute, 5);
}

Getting errors.

I think you misunderstood my question so I'll repost. First I wanna say thanks for taking the time to answer me and for the video. But I already know how to add Other Data series and indicators to charts.

The Question is For "INDICATOR DEVELOPMENT ONLY"


HOW Do I add the Volume from another Dataseries to my current Indicator Code?

i.e. IF (VOLUME from 6J )....I don't know the syntax or the coding method. it's just an example.

The NT Help is a great resource, but only if we use it. The example in the guide answers the question that you asked.

Add the instrument to the indicator and query the Volumes array.

Not for Charting for Indicator Development!
