How to get rid of old positions in sim?

[stosh]

I have some old wheat contracts from may (ZW 05-17) sitting in my sim account. I want to get rid of them so they don't show on my positions. When I try to flatten I get an error message"no market data available to drive sim engine". Is there a way to flush this position from my sim account? thanks

Hello stosh,
I would recommend resetting your simulator to remove and existing contracts from the ZW past contracts.
Resetting a simulation account will clear all historical trade data from this account. Please follow the instructions below to reset a simulation account.

From the NinjaTrader Control Center window select the Accounts tab
Right click on your simulation account and select 'Edit Account'
Press the "Reset" button

That worked. Thank you very much.
