In terms of volume, Interactive Brokers is technically the largest online stock trading platform in the U.S. It also advertises itself as the “lowest cost broker,” and for good reason: It only charges a startlingly low $0.005 per trade on stocks, ETFs, options, bonds, mutual funds, and futures (plus a 7 cent per contract fee for options). Technically, that’s still higher than Robinhood, but Robinhood only offers stocks, ETFs, and options (and as we noted above, Robinhood does skim some money off the top of trades via “payment for order flow”).
Shouldn’t I just choose the cheapest broker? Trading costs definitely matter to active and high-volume traders. If you’re a high-volume trader — buying bundles of 100 to 500 shares at a time, for example — Interactive Brokers and TradeStation are cost-effective options. Ally Invest offers $3.95 trades ($1 off full price) for investors who place more than 30 trades a quarter. Commissions are less of a factor for buy-and-hold investors, a strategy we recommend for the majority of people. Most online brokers charge from $5 to $7 per trade. But other factors — access to a range of investments or training tools — may be more valuable than saving a few bucks when you purchase shares.
TD Ameritrade offers two best-in-class platforms, designed for two different types of investors. Both platforms are free to use for any investor with a TD Ameritrade account. The web-based Trade Architect, though often in the shadow of thinkorswim, is streamlined and easy to use. It will appeal to beginning investors or anyone who prefers a simplified educational interface. Its tab-based navigation lets users flip between trading tools and account overview, plus charts, stock screeners, heat maps, and more.
$4.95 commission applies to online U.S. equity trades in a Fidelity retail account only for Fidelity Brokerage Services LLC retail clients. Sell orders are subject to an activity assessment fee (from $0.01 to $0.03 per $1,000 of principal). Other conditions may apply. See Fidelity.com/commissions for details. Employee equity compensation transactions and accounts managed by advisors or intermediaries through Fidelity Clearing & Custody Solutions® are subject to different commission schedules.
With the advent of online trading, there are a number of discount brokers with no (or very low) minimum deposit restrictions. One of the most popular online trading sites is ShareBuilder. You will, however, be faced with other restrictions and see higher fees for certain types of trades. This is something an investor with a $1,000 starting balance should take into account if he or she wants to invest in stocks.
