Closing out an old position

[tradetree]

I had a strategy that was operating on TF 09-11 in a simulation account. I disabled it awhile back but still had an open sim position. I can't close the position because it says there is "No market data for the simulation engine." This is clearly because TF 09-11 is now expired. How do I clear this out?

TradeTree,

Thank you for your post.

Resetting a simulation account will clear all historical trade data from this account, including the offending order. Please follow the instructions below to reset a simulation account.

From the NinjaTrader Control Center window select the menu Tools > Options
Select the "Simulator" tab
Press the "Reset" button

Please let me know if that works for you.

Yes, all set. Thanks.
