Historic Data source

[Majorshi]

Hi there,

I have difficulty in getting longer historic data for backtesting. I currently use IB for data source to backtest my strategies with some futures like GC, SI, CL, ES, etc., however, IB seems only provide about 2 years historic data, How can I get more and longer historic data? Is there any format issues?

and the backtest results for very similiar contracts like GC and YG (they are both for Gold products, but from different exchange) are quite different. data difference reasons? Hopefully get help.

Hello,

Most data providers will limit to about 2-years of historical data, however you should check with the data providers to be sure.

If you need more historical data, you can purchase and import that data from various suppliers. They will need to either be in a txt file or MetaStock file type.

We do not have any recommended vendors for obtaining this data.

Please see our Help Guide article on Importing Data for more information:

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?importing.htm

While YG and GC are very similar, they are traded at different exchanges and will have different OHLC and Volume prices during the same time period, which will result in different signals being processed.

Error on importing historical data

I have data which is in .txt format and is in the tick data format prescribed by NT. However, when I try to import it using Historical data manager, I get an error "There was an error importing data. Please check log".

Checked the message and I get an error Unable to import data ES-03-03. Instrument is not support. Does this mean I need to add ES-0303 as an instrument? Is it not adequate to have say ES 12-11?

I tried adding ES 03-03, but could not figure out how to add it

Hello,

Can you please clarify what the name of the file is you're trying to import? The correct format should be ES 12-11.Last.txt

Importing Historical Data

Hello,

Can you please clarify what the name of the file is you're trying to import? The correct format should be ES 12-11.Last.txt

The file name was ES 03-03.txt. I tried changing it to ES 03-03.Last.txt. It still did not work. I get the error "unable to import file .... Instrument is not supported.

[NinjaTrader_Matthew]

Hello,

ES 03-03 likely does not exist in your instrument manager.

This is a known limitation that will be fixed in a future release.


The contract dates only go so far back and are based on your local PC clock. To get past dates, you must set your PC clock back to that year and restart NinjaTrader.


After you have set your clock back, you can add this instrument to your default instrument list. Once added, shut down NinjaTrader and set your PC clock to the current date/time settings.


You should then be able to access this old expiry from your default instrument list.

Similar Problem with Historical Data

Matthew,

Thought I would piggyback onto this thread as I have similar problem with historical data. I have imported a text file named ES 12-11.Last.txt into Ninjatrader with data going back to March of this year.

I am able to see March data in edit tab of the Historical Data Manager, but when run a backtest, nothing executes earlier than 18-Jul-11 of this year. The only clue I can come up with is this is about when I started using Ninjatrader.

Thanks

Gennaker,

I am happy to assist you.

What sort of strategy are you using? You could attempt to use the continuous contract instead of ES 12-11 if your data provider offers this. The continuous contract has expiry ##-## and can be added in the instrument manager.

Please let me know if I may assist further.

[Gennaker]

That fixed it

Thank you Adam P. It is executing back through all the dates now.

Historical data problem

Hello,

I have emailed it also to the helpdesk.
I have the following (frustating) problem. I use the FDAX with minutes.
At this moment it is the 12-11. Connecting with IB Works fine for two years of data.
I can do a fine backtest. etc.

Now I have bought Fdax data from 1/1/2006 till half 2009. I have changed the format and the file is ok now.

It is possible to read all the data with the historical data manager. It is merged with the 12-11 FDAX future. I can see this if I do edit in the Historical datamanager. Also I can see nice charts from 1/1/2006 till now.

But the big problem is the following. If I run the Strategy analyzer it refuses to analyze the data from 1/1/2006 tll whatever time. After a second the analyzer give back results all 0.

Hope somebody can help me.
Regards
Niels
