Important Considerations
Performance Impact
After clearing the cache, initial load times may be longer as NinjaTrader rebuilds its data.
Backup Your Data
Back up any important settings, templates, or custom instruments.
Use NinjaTrader’s built-in backup feature for safe and easy backups.
Regular Maintenance
Periodically clearing your cache helps resolve performance issues, especially those related to corrupted or outdated data.
