Hello JakeOfSpades,

Thank you for posting.

We advise that you rename your database using the following steps :

• Shutdown NinjaTrader and Go to the Start Menu
• Select My Documents--> NinjaTrader 8--> db--> "NinjaTrader.sqlite" file (may only say 'NinjaTrader' depending on your Windows File Explorer settings)
• Right click on NinjaTrader.sqlite and select "Rename"
• Name it "OLDNinjaTrader.sqlite"
• Then restart the software and NinjaTrader will create a fresh database file to use

Unfortunately the following items stored in the old database will be lost - Trading Hours templates, Instrument Lists / Custom Instruments, historical trade execution data, saved Strategy Analyzer backtest results.

Please let me know if the issue persists after this procedure.

Did not help ,if you look at the trace error it's clearly a CQG Web API error.

So I may look into this further please go to Help->Email Support and be sure to include Attn: Chris Jameson in the Subject line, a link to this thread in the body and a check in the box for "Log and trace files".

Thanks in advance.
