Bars.GetDayBar( 1 ) always returns null using Playback

[daqu40]

Hello ID,

I've built an indicator to plot various values and I'm using Bars.GetDayBar( 1 ) to get the High and Low of the previous day.

It works great except when I run it with the Playback connection. I've tried using different settings in the GoTo and even let it run for a few days of time to see if it just needed to have at least a day pass on the chart. Nothing has worked.

Any ideas?

Hello, thanks for writing in.

There must be enough intraday historical data on the chart to calculate the daily bar. The best way to do this would be to connect to a data feed and download the historical data through the Tools>Historical Data downloading tool. After you load the chart with sufficient historical data the day bar will be able to calculate.

Please let me know if I can assist any further.

Thanks for the reply Chris.

There is plenty of historical data as evidenced by this screenshot:


Now the same configuration, but using my delayed data feed.


The new red and green lines come from Bars.GetDayBar(1) not returning null.

I've also let it run in Playback for multiple trading days in a row and it is never able to get anything but null on a call to Bars.GetDayBar( 1 ).

Hello, thanks for your reply.

I'm able to get daily data from the function with my simple test script. I attached it to this post, what do you get in the output window when running this on your chart?

I look forward to hearing from you.

Thanks for the example Chris.

It doesn't work on my system.

I do see that I'm a release behind, so I'm updating and seeing if that fixes it.

That didn't get it working. I've also tried looking back infinite bars.

Next I'm going to delete the Playback and historical data and reload it.

Hello, thanks for your reply.

If your other tests are not working I recommend making a clean environment to test in:

To create a clean installation please follow the instructions below:

1. Go to Documents\NinjaTrader 8 and copy your Config.txt file to the desktop, you will replace the new "Config.txt" that gets generated with this saved copy so you don't have to enter your connection info and license key again.
2. Exit the platform
3. Go to (My) Documents > rename the 'NinjaTrader 8' folder to 'NinjaTrader 8.Prev'.
4. Then re-install by running the installer from the following link: https://ninjatrader.com/GetStarted
5. When you reinstall it will recreate the user folder you had just renamed with only stock files.

Now you can start the platform and import the example. Test with new data.

To switch between the two installs; shut down NinjaTrader > rename the new installation to 'NinjaTrader 8.Dev' under (My) Documents > then rename the 'NinjaTrader 8.Prev' to 'NinjaTrader 8'. NinjaTrader looks for the user folder named NinjaTrader 8 specifically.

Still not working. I'm on to complete reinstall of Ninja 8.

[daqu40]

Complete reinstall and it's still not working on the Playback connection, but works fine on any other connection.

[daqu40]

New behavior I'm seeing is that once the Playback connection is used, the simulated connection will also fail. Then connecting with an external connection restores function until Playback is used again.

I'm thinking we need to get one of your team on my system to see what's happening.
