First time user of IB here, anyone know how to make it so it is not greyed out? Couldn't find it in any help threads. Thanks
Go to Global configuration, choose 'STK' under order defaults and in the box that appears, Check "allow orders to be filled outside regular trading hours"
I'm proud of you for at least realizing it's there, instead of posting the usual "Stupid IB won't send in orders!...", like so many others.
BE CAREFUL with that after hours stuff...its a good way to destroy your new account! don't go hitting to many bids or offers...trust me on this, you will almost ALWAYS get a better price during regular hours...
