Ninjatrader very slow to start up

[samish18]

When I open up ninjatrader, it takes at least several minutes to boot up. This issue has become more noticeable since I've been running strategies. How can I fix this issue.

Hello samish18,

Thanks for your post.

Are you trying to load multiple workspaces when NinjaTrader starts up?

Do you have a large number of charts loading with indicators/strategies applied to those charts?

The impact NinjaTrader has on your PC will be dependent on how much NinjaTrader has to calculate upon startup. We typically advise the following as tips to improve platform performance.

1. Configure charts so their Days To Load is an absolute minimum, just enough for your indicators to function properly
2. Configure indicators to use Calculate.OnBarClose when possible as opposed to Calculate.OnPriceChange and Calculate.OnEachTick.
3. Use less charts and less complex indicators
4. Avoid using Tick Replay.

Let's try testing your platform in Safe Mode to verify if this behavior is caused by a 3rd-party add-on or is isolated to your Workspace using the steps below. Safe Mode will prevent NinjaTrader from:

• Loading workspaces and connecting on start-up.
• Loading custom assemblies (3rd-party add-ons and NinjaScripts)
• Getting instrument updates from the server

To open the platform in Safe Mode:

• Go to the Windows Start Menu
• Search for NinjaTrader > select 'NinjaTrader (Safe Mode)'
• Once you have opened the platform in Safe Mode, you may manually connect to your Data Provider from the Connections dropdown

Once you are connected, open a new chart with no custom bar types, indicators, or templates and test for issues. Does the behavior persist on this blank Workspace in Safe Mode?

If not, please try opening your previous workspace from the Control Center > Workspaces dropdown. It may already appear as open. Hit 'close' and do not save, then re-open it again for your windows to appear. You will notice that no 3rd-party add-ons are available in Safe Mode. Does the behavior return to your regular Workspace in Safe Mode?

If not, restart NinjaTrader normally, and test for the behavior on your Workspace normally once more with your 3rd-party add-ons available. If the issue returns, we suggest rebuilding your workspace. Keep track of each add-on you implement to identify the cause of the behavior should it return. If the issue does not resurface, it confirms the error was isolated only to your other Workspace.

We also suggest backing up your workspace (Tools > Export > Backup) so you may restore a working version if the issue returns. Additional information about backups may be read here in our Help Center.

Please let us know the results of this test. We look forward to your response.
