Order type not permitted while the market is in pre open Exchange

[MatthewLesko]

Around 3:15 PM CST I'm getting this error, does anyone know how to resolve it? I'm simply trying to close a trade I thought was simulated but actually is real, and now I am unable to.
I thought I could trade Futures beyond regular stock market hours?

Edit: It's working now, so it's the pre market closure that disables it.
What's the penalty if I leave it open on futures during this brief period?

Thanks for the reply. It says there was a sell though so I'm not sure if it was lagged and went through or not.
In the "Positions" tab I don't see anything. Does that mean I should be good?

Ok should be good.
