Sorry to say that for both options and stocks, TradeKing's services/execution has been only sub par even if you campare it against deep discount brokers. It is getting uglier.
I tried TradeKing...it really sucked....I sent in my money and tried to trade but the system is slow and the service is non existent...when i called to complain, this guy name Kimbo told me to shut the F#ck up and quit whinning like a girl....when i told him it was improper to treat me that way, he said he was "gonna send some pipe carrying mo-fo's down to my house to bust me up real slow"
I've been in fear of my life ever since... ...Damn you TradeKing! Damn You!
I've actually had a pretty great experience with TradeKing. I'm new to options trading but they make it pretty easy. There's a pretty cool Profit/Loss calcualtor that helps me find my way through things.
I've used their online chat help a few times and, while it's not lightning quick, at least it's a real person and it's still quicker than waiting for an email response or sitting on hold, which is what I get when I call any other place.
