Ruler causes crash

[Tradexxx]

Every time I use the ruler, the desktop version of NinjaTrader freezes completely.
The only thing that keeps going are the updates in market analyzer window.

Than i can only end it via the task manager.

But there's no load spike visible in the task manager itself.

I have already reinstalled NT. But no change.

What can I do?

Hello Tradexxx,

Thank you for the message.

Please use the following steps to open the platform in Safe Mode and create a "Test" workspace to see if the ruler still causes the platform to crash outside of your normal workspace without any add-ons loaded in.

• If the behaviors don't continue in Safe Mode, save the "Test" workspace and then reopen NinjaTrader like normal to the Test workspace and see if the behaviors continue.
• If the behavior hasn't returned, reopen the Original workspace to see if this behavior comes back and is specific to your original workspace.

Safe Mode will prevent NinjaTrader from:

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

To enable Safe Mode, please use the following steps:

• Shut down NinjaTrader.
• Hold the CTRL key and double-click the NinjaTrader icon.
• Keep holding the CTRL key until you see the Sign in Window then sign in (If the logo is Maroon, hold until you see the Control Center since this is an Older version)
• You may then verify you are in Safe Mode by going to Help -> About.

Once you have opened the platform in Safe Mode:

• Reconnect to your Data Provider
• Go to the Control Center > Workspaces > Click new > Call it "Test" > Click OK
  • Please open a new chart with no custom bar types/indicators/templates and test for issues.
  • Create a small Test workspace using Default NinjaTrader Indicators only and test if the behavior continues.

Does the behavior persist on this "Test" Workspace in Safe Mode?

• If the behavior is no longer happening, go to the Control Center > Workspaces > Hover over "Test" > Click save
• Restart NinjaTrader and open the platform like normal. Click "NO" if it asks to save again.

NinjaTrader should open to the "Test" workspace in Normal mode now:

• Connect to your Market Data and test if the behavior continues while here on the Test Workspace in Normal mode.
• If there are no errors, try opening your original workspace

Do the errors return when you re-open the Original Workspace?

• If yes, this confirms that the unwanted behavior is being caused by something within the original workspace specifically.
• You could either:
  • Remove things from the Original Workspace 1-by-1 until the unwanted behaviors go away and you will know the last thing removed was causing it.
  • Or, continue with the Test Workspace and build it back up 1-by-1 until the behaviors return so you know the last thing added back in is causing the unwanted behaviors
    • Once you narrow in on what is causing the Unwanted behaviors, you could reach out to the developer for further help and information on why it is happening and what must be done to avoid it moving forward.

Please let us know if the unwanted behaviors continued while opening NinjaTrader in Safe Mode or to the "Test" workspace in Normal Mode.

Please let us know if we may provide any further assistance.

Hi Clayton,
thank you for the information.

I followed your suggestions one by one.

It looks like this:
It runs fine in safe mode.
Test workspace runs also fine in normal start.

When I returned to my previous workspace, the problems returned again.

So I'll try to create the workspace completely new.

Thank you very much, that was very helpful!
