NinjaTrader freezes up

[75_martin]

Hi,

The last couple of days my NT platform has begun to get these microsfreezes that seem to be increasing in severity. It will freeze when I try to navigate in the charts, when I switch timeframe (beside the usual delay from loading). Pretty much anything I try to do cause the platform to freeze up from anywhere to a few seconds to 20-30 secons.

Is there a cache I can clear out?

Any suggestions that are helpful is much appreciated.

Thanks,
Martin

Hello Martin,

You can experience freezing and unresponsive behavior in NinjaTrader if you have many charts, indicators and other windows opened depending on market volatility as well.

The 'Calculate on bar close' setting for indicators can be important. If set to False, the indicator will be calculated on each incoming tick. During high volatlity this can be very CPU intensive especially if the indicator makes complicated calculations. Please set it to True in the Indicator menu and the indicator will only be calculated at the end of each price bar.

If you have workspaces opened in the background which you do not use, we suggest to close such workspaces. Please go to Control Center-->File-->Workspaces and check what workspaces are listed below 'Save Workspace As'. The workspace with the checkmark is the workspace opened on your monitor. Any additional workspaces listed, are opened in the background.

Please select a workspace without the checkmark. Subsequently, go to Control Center-->File-->Workspaces-->Close Workspace. Repeat this procedure until only 1 workspace is opened. More tips and suggestions to improve the performance of NinjaTrader can be found at the link below.

Closing the open workspaces seems to have resolved the issue.

Thank you for the extremely quick reply.

Best regards,

Hi,

I closed and then removed the workspaces that were open. Now when restarting the platform it does not load any charts at all and then freezes.

Can I reset the platform in some way?

Thanks,
Martin
