Ninja 8 Data Stability Instructions

Ninja Trader 8 daily clean up will be required for a stable trading day.
NINJA 8 works with Windows 10 & 11 & 16-32 GB RAM. Nexgen recommends upgrading to 64 GB RAM; anything over 64 GB is overkill. Following the steps outlined below is essential to ensure optimal performance and a smooth trading experience.
By diligently executing these steps, including deleting tick and cached data, DB tick files, temporary data, and the workspace recovery folder, users can proactively maintain stability and optimize the performance of the Ninja 8 platform.
Watch this short video or follow the written instructions below to clean NT8 data and prepare for the trading day.

To delete cached tick data- BROWSE TO DOCUMENTS> NINJATRADER 8> DB folder or \Documents\NinjaTrader 8\db. Deletion of DB Tick Files: In addition to the tick and cached data removal, it is imperative to delete the DB tick files. These files store historical tick data and can accumulate over time, potentially leading to increased memory usage and performance degradation. Removing these files regularly ensures a clean and optimized database for the Ninja 8 platform.

When utilizing Ninja Trader 7, it is strongly advised to double-check the merge policy for your data to ensure accurate historical prices. Specifically, the merge policy should be set to "DO NOT MERGE." Failure to adhere to this recommendation may result in the platform stitching together past contract prices and making adjustments that deviate from the actual price movements.
These adjustments can introduce discrepancies in the historical prices displayed on the charts, complicating the analysis of Fibonacci levels. To rectify this issue, if you need to change your merge policy, you must re-clean your data to remove the historical data affected by these price offsets.
To illustrate this matter visually, refer to the accompanying picture.
