"NinjaTrader should not be used with OneDrive as you will see file access violations and other issues when OneDrive tries to sync files to the cloud" - NinjaTrader.
Overview of the Problem
NinjaTrader is incompatible with cloud storage services like OneDrive, Google Drive, and similar continuous backup solutions. Using these services can lead to significant issues with your trading platform's performance, data integrity, and overall functionality.
Potential Risks of Using OneDrive with NinjaTrader
1. File Access and Synchronization Issues
- File Locking Conflicts: OneDrive can create duplicate files and "conflicted copy" errors when attempting to sync files actively used by NinjaTrader.
- Sync Interference: The platform may experience file access violations and invalid path errors during critical operations like add-on installation or updates.
2. Data Integrity Risks
- Potential Data Corruption: Continuous syncing of open database files increases the risk of file corruption.
-
Consequences of Corruption:
- Platform crashes
- Missing data
- Difficulties reopening NinjaTrader
- Loss of trade records
- Disrupted trading configurations
3. Performance Challenges
- Resource Consumption: OneDrive syncing consumes system resources
-
Performance Impact:
- Slowed NinjaTrader performance
- Sluggish platform responses
- Potential interference with real-time data feeds
- Bandwidth consumption
- Delays in charting and order execution
Why Does This Happen?
NinjaTrader requires storing user files in the My Documents folder, typically in a "NinjaTrader 8" subdirectory. When NinjaTrader attempts to access a file being backed up or accessed by OneDrive, conflicts arise that can prevent proper file management.
Symptoms of OneDrive-Related Issues
- Intermittent platform problems
- Unexplained errors
- Messages indicating file corruption
- Charts failing to open
- Add-on installation complications
Comprehensive Solution: Removing OneDrive Interference
Step 1: Disable OneDrive Backup
- Hover over the OneDrive icon in the App Tray
- Right-click and select Settings
- Go to the 'Backup' tab
- Stop backup for the Documents folder
Step 2: Move Files to Local Storage
- Open OneDrive Documents location
- Open local Documents folder
- Copy entire NinjaTrader 8 folder to local Documents
- Use separate windows for easier navigation
Step 3: Soft Reinstall NinjaTrader
- Open Windows Control Panel
- Go to Programs > Programs and Features
- Locate NinjaTrader
- Right-click and select Uninstall
- Download and install NinjaTrader Desktop by logging in to your user dashboard with the following link: https://account.ninjatrader.com
