IB connection - some charts void

[asapowell]

Ninjatrader doesn't load data for some futures that I can graph in TWS.

It keeps saying forever .. loading data....

Hello asapowell,

Please disconnect from Interactive Brokers, reset the instruments, repair the database and restart NinjaTrader.

To reset your instruments please: go to the Tools menu, select the Options menu item, select the Data tab, and then click on 'Reset Instruments'.

Please follow the instructions below to repair the NinjaTrader database.

Disconnect NinjaTrader from any open connections via File > Disconnect
From the NinjaTrader Control Center window select the menu Tools > Options
Select the "Data" tab
Press the "Repair DB" button
Press the "OK" button

ok, it fixed the problem.
I have TWS v933. Can I stay with that or have I to downgrade to 927?

Hello asapowell,

I would recommend downgrading to TWS 927.7 as this build has been tested and is supported. You can download TWS 927.7 from the link below.
