Can You Use Multiple Trade Copiers at Once?

Yes, you can run multiple trade copiers simultaneously in NinjaTrader to manage trades across different accounts or prop firms. However, proper setup and resource management are essential to avoid conflicts and performance issues.

Best Practices for Multi-Copier Setups

• Duplicate in a New Tab
  Right-click on the Trade Copier tab and select “Duplicate in New Tab” to open another instance quickly. Keeping all copiers within a single chart window is recommended to minimize graphics load and maintain optimal system performance. You can run multiple chart windows, but this may slow down the platform.
• Use Separate Accounts per Copier
  Assign unique follower accounts to each copier to avoid cross-execution issues, such as simultaneous “Flatten All” commands affecting multiple copiers or duplicate contracts.
• Test with Micro Contracts
  Start with single micro contracts to verify that your copier setup is functioning correctly before increasing trade size.

Things to Watch Out For

• Duplicating accounts across copiers can result in order conflicts or unexpected behavior.
• Running multiple copiers can slow down the platform if not managed properly.
• Isolate and test one copier at a time if you experience technical issues.

Final Thoughts

Running multiple trade copiers in NinjaTrader is fully supported, but requires attention to account setup and platform performance. Following these practices helps ensure smooth operation when managing multiple accounts or prop firm logins.

How two copier windows work together

Each copier window has its own Master account and its own Follower accounts. A few built-in rules stop two windows from copying the same trade twice:

• Duplicated windows start safely. When you use Duplicate In New Tab, the new window keeps the same Followers and per-account settings, but no Master is selected and its copier is off. Pick a Master and turn it on when you are ready.
• Same Master and Followers in two windows. Only one window can copy at a time. The window you turn on last takes over and the other window’s copier is switched off. Nothing is flattened or cancelled when this happens.
• Different Masters sharing a Follower. By default this is treated as a conflict, because one account would be traded by two Masters. The copiers involved are switched off and a banner names the shared account. Remove that Follower from one window to continue.
• Allow Multiple Windows (Shared Followers). If you really want two Masters to share Followers, turn this advanced setting on in both windows. Then only one window trades a given Follower on a given instrument at a time, until that position is flat.

To tell windows apart, the Tab Name Format setting can show each window’s Master and on/off status in its tab name. Full details are in the user manual in the Members Area, and the trade copier page explains the product.
