While I’m very happy trading stocks and options through Thinkorswim, I’m considering a second account with TradeKing. I have my doubts that TradeKing’s customer service is as good as Thinkorswim’s, but the commissions are dirt cheap. For options trades, TradeKing charges just $4.95 + 65 cents per contract. My current plan at Thinkorswim charges the lesser of 1) $2.95 per contract, or $9.95 + $1.50 per contract.
TradeKing was also just rated 5 stars by TopConsumerReviews.com, beating out the likes of Scottrade, OptionsXpress (OXPS), Sogo Trade, and Zecco. Not bad for a little guy.
