Hello silverness,

Thank you for your post.

The Free Edition NinjaTrader license key will not expire & allow you to work with all features of the NinjaTrader platform. This Free Edition key begins with ‘@SIM’. The only limitation is that you can only trade in simulation mode. If you acquire a live NinjaTrader license key then you can connect to your NinjaTrader-supported broker & place Live trades.

If you have a different license key then send an email to support AT ninjatrader DOT com & we can look this up for you.
