US 10 Year bonds instrument

[EastLondonKiwi]

Thanks Jessica

My settings match your settings, so I have to assume it's my data feed.

Thanks

I found that instrument in the database, and I can add that to a chart, but I get no data from it? does that mean I am limited in the data type my licenses allows me to access

Usually this is the case. I would like to invite you to visit Tools -> Instruments, find and edit your ZN instrument, and compare your settings to those I have attached, to ensure that your instrument mappings are not causing this. 06-17 is a recent expiry date.

Thanks Jessica

I will look at your code again and access, however I am still sure the list in your code is the derived lists to enable a user to group specific instruments together making finding them later easier, and while I could use these lists as the basis for my indicator, I would rather have a more generic method I can use for wider purposes. So I will keep battling on with figuring out how to address the output. Oh and for clarification I am using the Output window for assessing the results.

Ok that said can you also have a look at the instrument ZN 06-17 that is the US 10 year bonds futures instrument.

I found that instrument in the database, and I can add that to a chart, but I get no data from it? does that mean I am limited in the data type my licenses allows me to access or is there some other issue I need to address.

Thanks

We are discussing undocumented functionality and parts of NinjaTrader we do not directly support. Discovering how to filter down to a specific instrument list is a trial and error investigative process. This said the code example I posted earlier was tried inside an indicator's onbarupdate routine, and if you will carefully analyze the difference between my code and your code I believe you will be able to see a point where the code I posted is capable of making this distinction already. I recommend running it in a new indicator as the indicator's entire onbarupdate method, with a ninjascript output window already open, then pressing ctrl+a, ctrl+c inside the output window, and finally pasting the copied output into your favorite text editor. If you look inside the output for a known symbol, for example, the ES 06-17, then look upward from there, and compare this to the code, you should be able to discover how to filter based on instrument list.

Jessica Ok I am getting there.

Firstly. Calling NinjaTrader.Cbi.Instrument must be within the method OnStateChange, trying to call it from OnBarUpdate causes an error

Once I figured that out I got results I was after

Then I realised the Instrument list is a derived list made by a User, and is not the list of Instrument I want to check. I am after the entire list of instruments my NinjaTrader database contains. So based on your example I got to this point.

foreach (NinjaTrader.Cbi.Instrument l in NinjaTrader.Cbi.Instrument.All)
{
   Print(l.MasterInstrument.Name)
{

However. this is now more data than I need and I want to only add to a variable those name where the InstrumentType equals "Forex"

but I am having a blond moment and can not figure out how to cast l.MasterInstrument.InstrumentType to a string. I had thought this would work, but I was wrong:

foreach (NinjaTrader.Cbi.Instrument l in NinjaTrader.Cbi.Instrument.All)
{
   where(l.MasterInstrument.InstrumentType.ToString.Contains("Forex"))
        {
           Print(l.MasterInstrument.Name)
        }
{

Can you advise

Thanks

Thanks Jessica you are a star

Thank you for your question Duncan. While there is no supported method for doing this, other users have had some luck investigating the undocumented object NinjaTrader.Cbi.InstrumentList.All . Undocumented code can not be supported nor guaranteed to be maintained. However, for the moment, the following block of code will work.

[FONT=Courier New]
        protected override void OnBarUpdate()
        {
            foreach(NinjaTrader.Cbi.InstrumentList l in NinjaTrader.Cbi.InstrumentList.All)
            {
                Print(l.Name);
                foreach(Instrument i in l.Instruments)
                {
                    Print(i.FullName);
                }
            }
        }[/FONT]

Thanks Eric. I'll check out ZN.

in Ninja script 8 what is the method I could call that lists all the Instruments? and what properties can be derived from it?

Eg Name, Type (Futures, Forex) etc...

Kind regards

Hello EastLondonKiwi,

Thank you for your post,

The 10 Year US Bonds is listed in NinjaTrader as "ZN."

To view this, I suggest going to New > Chart > Select the magnifying glass > Search "ZN" and select by double-clicking > OK to open the chart.

Once this is complete, you'll then be able to access the ZN from every instrument drop-down list.

Hi

I am struggling to find the US 10 year bonds instrument, in the instrument list I have.

Can support either point me at the correct instrument name or point me at a help guide reference that explains how to load it.

Kind regards
