External data feed- there is no market data

[Atomic]

I keep getting the warning that there is no market data available to drive the simulation engine even though there is. Any advice?

Should I do this on a regular basis?

It's still happening anyway.

Hello Atomic,

Thank you for your response.


No, this is generally only used as a troubleshooting step if you get errors such as this, but it can also be used as a tool to reset and customize the Sim101 account as you may need.

In addition to the Sim101 account, you may create new Simulation accounts by right-clicking in the Control Center > Accounts window and selecting 'Add Simulation Account'.

For more information on Simulation Accounts, you may visit the links from our NinjaTrader 8 Help Guide below:

• Simulation Overview
• The Sim101 Account
• Global Simulation Mode

Please let me know if you have any additional questions.

I used to do this with fewer symbols, but now I have 8. I think that may be part of the problem.

In the simulator settings, there is a Wait For Data setting of 60 seconds. Would changing this help.

I do not find a way to add a simulated account by doing as you described. This is NT7.

Hello Atomic,
Thank you for your response.


For NinjaTrader 7, you will be able to manage, reset, and edit simulation accounts from the Tools > Options > Simulator window rather than in the Control Center itself. A lot of the same things will apply though for both platforms.

Please let me know if you have any additional questions.
