I am a current IB user and I get picks late Friday night from the system that gives me picks which I usually hold for a month or so. It seems as if my slippage on Mondays is going through the roof, maybe on account of other people following the same picks. Is it worth it to consider premarket trading? What's the best way to go about trading premarket? If I buy at the open on Monday morning, any ideas on the best way to route the order? On another note, I've noticed that IB doesn't let you place orders until Sunday night. Is it better to get your market order early versus later when it comes to IB? Should I use a better broker? Sorry for all these questions, but I'm trying to learn how this all works. I really appreciate any help you can provide.
