How Do You Reset Frozen Orders in NinjaTrader?

This page is about orders that are stuck on a simulated account. If the whole NinjaTrader platform is frozen or not responding, see NinjaTrader freezing or not responding.

Frozen orders can sometimes appear when using simulated accounts in NinjaTrader. These will typically show up as yellow orders that are unclickable. This issue does not affect live trading accounts. If you’re seeing orders stuck on your chart that won’t go away, there are two primary methods to clear them.

Method 1: Reset the Simulated Account

1. In the NinjaTrader Control Center, go to the Accounts tab.

2. Select the simulated account with the frozen orders.

3. Right-click on the account and choose Edit Account…

4. In the Properties section, click Reset.

5. Ensure Clear History is checked, then confirm by clicking Yes.

6. The NinjaTrader 8 platform may appear unresponsive during this process—wait patiently, and it will complete the reset.

This method clears all order and performance history for the simulated account.

Method 2: Remove Frozen Orders Without Clearing History

1. In the Control Center, go to Tools > Database Management.

2. In the Database Management window, check the option for Reset DB.

3. Make sure only Historical Orders is selected.

4. Click the Reset button.

This method removes frozen orders while preserving your performance history.

By using either of these methods, you can effectively remove frozen simulated orders and keep your chart clean and functional.

Before you reset

• Try cancelling first. In the Control Center, open the Orders tab, right-click the stuck order and choose Cancel. If it cancels, you do not need either method.
• Make a backup. Both methods remove saved history. To keep a copy of your setup, go to Tools > Export > Backup File in the Control Center first.

Which method should I choose?

Use Method 1 when you are happy to start the simulated account fresh. The reset clears its orders, positions and trade history and puts the account back to its starting cash value. Method 1 only affects the simulated account you selected; your other accounts are left as they are. Use Method 2 when you want to keep your performance history and only remove the stuck orders.

After either method, restart NinjaTrader and check the Orders tab and your charts. If frozen orders keep coming back, or you see them on a live account, take a screenshot of the Orders tab and the Control Center Log tab and send it to us through the help chat, or contact your broker for a live account.
