Bottom Line

TradeKing consistently garners praise for its low-cost commissions (Est. $5 a trade with no minimums) but the broker also wins awards for outstanding customer service. TradeKing also offers a strong online community for investors, which is still a rarity among brokers.

Ease of use

Improved, clean interface. TradeKing, which merged with the online brokerage Zecco, is one of the most popular discount brokers because of its low-cost trades. The company doesn't have the most sophisticated interface, but recently redesigned its account summary page and condensed the most crucial information -- a quote box, account balances, investment holdings, order status and more are included on a single page.
