Which brokerage should I use?

Just about any online brokerage is fine—Fidelity, Merrill Lynch, eTrade, etc.. There are countless out there and these days most of them have eliminated commissions. We don’t highly recommend any one over another, though currently we are using Tastyworks, and many of our international members have found Interactive Brokers to be a good fit for them. If you already have an account somewhere, it is likely that it will work just fine for you.
