ES (e-mini) some intraday data not displayed on chart

[skiguy]

Hello skiguy,

Thanks for your reply.

Has Traders Workstation 944.3 been installed?
When this happens do you have any charts that are not displaying data?
Do you have any charts with tick based data open? (tick, range, renko, second)

I am on TWS Build 950.2g and a very recent version of the API.

When this happens do you have any charts that are not displaying data? No

Do you have any charts with tick based data open? (tick, range, renko, second) No

Hello skiguy,

Thanks for your reply.

Do you still see this happen if you install the required version of Traders Workstation, 944.3?
You can download it from the link below.

http://www.ninjatrader.com/ninjatrader/TWS/tws40_install_944_3.exe

If so, do you get the error when running a blank workspace only?
Shut down NinjaTrader

• Navigate to (My) Documents\NinjaTrader 7\workspaces
  
• Delete the file named "_Workspaces.XML".
  
• After deleting this file, restart NinjaTrader which should startup without any workspaces.
  
• Once NinjaTrader has started on just the control center, please open a new chart with no custom bar types/indicators/templates and test for issue.
  
• *Please note this will not delete your workspace however the new blank workspace will be named Untitled1. If you have a workspace already named Untitled1 however you will not want to save the workspace when exiting NinjaTrader, otherwise it will overwrite it.

If there are no issues on this new workspace, please try opening the previous workspace by going to File--> Workspaces--> Open workspace.

just so I am crystal clear.

you want me to load an older version of TWS than the one I am currently using?

and specifically build 944.3

Build 944 was Build 944 - March 11, 2014 which is way out of date.

Hello skiguy,

Thanks for your reply.

That is correct. This is the required version. Newer versions have not been tested and may not work.

I have stated that NT can read the IB data and update it sometimes. It is not that NT cannot recognise the contract and pass the correct info to TWS in order to retrieve the data from IB. Rather it is, sometimes (and I think it is probably when NT is opened and the IB connection is made) that the error occurs.

So for example, after getting the error, I can reload historical data and it works (I provided this detail in an earlier post in this thread) and as stated I do not get the error.

As a further test, I closed the IB connection for 5 mins or so but left NT open. I then reconnected to IB. and did not get the error and then when I looked at the chart it was completely up to date i.e. the last bar was current in NT (1 min data) and I did not have to select “reload historical data”. This further proves that NT can pass the correct info to IB and that the data is returned correctly.

This is something that NT can easily investigate. I have worked in IT for over 25 years and this is a bread and butter IT issue IMO and NT should investigate the root cause of the issue rather than asking the user to revert to software that is over a year out of date and ask them to suck it and see.

I think it is up to NinjaTrader to provide a fix rather than me going back to a version of TWS that is already over a year old.

Could you please escalate the issue or tell me what I need to do to get it escalated.
