This guide walks you through safely rebuilding a NinjaTrader workspace to resolve stability issues such as crashes or restart loops. These steps do not change your Machine ID and do not require re-licensing any third-party software.
Rebuilding a workspace is often the most effective way to isolate corrupted workspace state or third-party add-ons that may be causing instability.
Before You Start (Important)
Creating a new workspace does NOT change your Machine ID
Your existing third-party licenses remain valid
This process does not reinstall NinjaTrader or your VPS
Your existing workspace will remain untouched unless you choose to remove it later
Step 1 — Close NinjaTrader Completely
Close all NinjaTrader windows
Confirm NinjaTrader is fully closed (no NinjaTrader processes running)
This ensures the new workspace starts from a clean state.
Step 2 — Create a Brand-New Workspace
Launch NinjaTrader
From the Control Center, click:
New → Workspace → New Workspace
Give the workspace a temporary name (for example: Clean_Test)
When the workspace opens, do not load any charts, indicators, strategies, or add-ons
You are now running NinjaTrader in a clean workspace state.
Step 3 — Confirm Platform Stability
Leave NinjaTrader running in this empty workspace for 10–15 minutes
Do not enable strategies or add-ons
Confirm that NinjaTrader remains stable and does not restart or crash
If NinjaTrader is stable at this stage, it confirms the base platform and system are healthy.
Step 4 — Gradually Rebuild the Workspace
Rebuild the workspace slowly and one component at a time. This is critical to identifying the trigger.
Recommended order:
Charts
Add one chart
Let NinjaTrader run for a few minutes
Indicators
Add indicators gradually
Confirm stability after each addition
Strategies
Enable strategies one at a time
Monitor for restarts
Add-ons (e.g., trade copiers)
Add last, one at a time
After each addition:
Pause for several minutes
Confirm NinjaTrader remains stable
If NinjaTrader restarts after adding a specific component, stop — that component is likely the cause.
Step 5 — Save and Use the Rebuilt Workspace
Once everything is loaded and stable:
Click Workspaces → Save
Optionally set this workspace as your default
Keep the old workspace as a backup, or remove it later once you’re confident the new one is stable
If Issues Continue
If NinjaTrader becomes unstable even with a clean workspace:
Contact support with details on which step caused the issue
We may recommend a NinjaTrader platform reinstall only
This still does not require a VPS reinstall
This still does not change your Machine ID
A full VPS reinstall is a last resort only and is not typically required.
