Computer Hardware

CPU speed is critical to NinjaTrader's perfomance.  See the CPU section of the Computer Selection Guide.

Microsoft OneDrive

MSOD is known to lock various files within the NinjaTrader working directory ( C:\Users\Documents\NinjaTrader 8\ ) and causing crashes and/or performance issues.  It is critical that you exclude the NinjaTrader 8 folder from OneDrive.  See Microsoft documentation for more information.

Anti-Virus Software

Common Anti-virus software such as Norton, McAfee, Bitdefender, and Microsoft Security Essentials, that have “Real Time Protection” scanning, are known to slow down NinjaTrader and cause memory issues.  Typically, NinjaTrader can be added to a Whitelist or ‘Exception List’ to prevent Real Time Protection from scanning the NinjaTrader folder and files.  In most cases this will greatly help NinjaTrader run faster.

Norton Anti-Virus

These instructions for turning off “Real Time Protection” were submitted to us by a customer.  Please contact Norton support for any assistance.

  1. Select “Settings” (upper left tab), “Real Time Protection”, “Antivirus and SONAR Exclusions”, and “Items to Exclude from Auto-Protect, SONAR and Download Intelligence Detection”.
  2. Select the “Add” drop-down list and then select “Folders”.
  3. Navigate to the folders containing your NinjaTrader program files [typically this is C:Program Files (x86)NinjaTrader 7.  Select this folder to add it to the Real Time Exclusions list.
  4. Click “Apply” and “OK” to accept the changes.


A customer has found Bitdefender to cause memory issues with NinjaTrader and BloodHound.  Follow this guide, How to add exclusions (exceptions) in Bitdefender 2015, to remove NinjaTrader from being scanned.  Comment: Aug. 2015, It has been reported to us that the Exclusion list does not work, and Bitdefender keeps interfering with NinjaTrader.  The customer had to uninstall Bitdefender.

Microsoft Security Essentials
