I’ve been in the market for about two years now and trying to learn as much as I can. After hours and pre-market trading is still such a mystery to me, but so much happens during these times that I feel like I need a better way to see what’s going on. I use the Fidelity app and Apple’s Stocks apps currently. I get plenty of info between the two but they’re both pretty limited in what they show in after-hours activity. I’m sure there are better tools out there.
