Historical Data

[grd974]

Is it possible to store streaming realtime data so as to build up some historical data at least over the 24 latest hours or the latest week ?

[NinjaTrader_Dierk]

Yes. Please check out the Tools->Options->Data->Store realtime bar data and related help docs: http://www.ninjatrader-support.com/HelpGuideV6/Data.html

If i have IQFeed can I download their historical data for Equities say 10 yrs back to NinjaTrader in some way so it stays in NT system or that would be proprietory data?
Thanks

[NinjaTrader_Ray]

Any historical data downloaded to NinjaTrader will remain on your local PC for future use in the NinjaTrader database.

Even if i accidentally need to reinstall NT? Can i do a data backup just in case?
Thanks

[NinjaTrader_Ray]

Yes, we have a back up feature and a historical data export feature as well.

[designer]

When I backup does the backup include the historical data as well?

[NinjaTrader_Ray]

Yes it can. Please see the relevant section of our Help Guide.

when I re-open a chart i had reloaded histotical data for the instrument from one session to the next, historical volume is not being saved why might that be?
Thanks

[NinjaTrader_Ray]

To clarify -

- Connect to your provider
- Open a chart and put on a volume indicator
- Reload historicald data --> You should see volume
- If you see volume, disconnect
- Shut down NT and save the workspace when asked
- Restart NT
--> Do you see the chart with the volume or is the volume indicator now showing anything?

I followed your instructions but when I Restarted NT still did not save all volume bars in the saved workspace charts only the last day of volume was saved.
Please advice.
Thanks.

Hello,

You are using IQFeed, what instrument are you charting? I will try to reproduce this.

[designer]

Interactive Brokers

I was using 30 minute charts in my comment.... when I saved with daily charts and restarted NT the daily volume was saved ok. So it must be the 30 min chart volume for some reason.
Please try it yourself.
Thanks

[designer]

I tried with 15 min charts and save ok. must be the 30 min charts then.

[NinjaTrader_Ben]

Hello,

Note the steps you are taking with the 15 minute timeframe and apply them to the 30 minute timeframe. There should be absolutely no difference in proceedure or the availability of volume data. If the 15 minute time frame works, the 30 minute time frame will work.

[designer]

i followed the same process for the 30 min charts, I still had problems with the following instrument symbols...DDM, QLD, SKF, of the ones i use.
Please try these as well.
Thanks.

I tested the DDM on my end while connected to IQFeed and it worked as expected on my end. See screenshot.
