The investing information provided on this page is for educational purposes only. NerdWallet does not offer advisory or brokerage services, nor does it recommend or advise investors to buy or sell particular stocks, securities or other investments.
Interactive Brokers and TD Ameritrade are both solid choices for advanced traders. But below, we'll compare these two brokers head-to-head to help you decide which is best for you.
Both brokers have extensive investment selections and access to quality research and tools. Interactive Brokers stands out for offering fractional shares — which is not yet table stakes among brokers — and if you're interested in cryptocurrencies, Interactive Brokers offers access to Bitcoin, Ethereum, Litecoin and Bitcoin Cash. Interactive Brokers traditionally has been geared toward a more active trader, not beginners, and the website is a bit harder to use than competitor sites.
TD Ameritrade doesn't offer fractional shares or direct access to crypto, but crypto-based products, such as Grayscale Bitcoin Trust, are available on the over-the-counter market. The broker is a good deal for beginner investors — it has more than 5,000 mutual funds on its platform with expense ratios of 0.50% or less and more than 3,000 with investment minimums of $100 or less. Read more details on both brokers and see which might better fit you.

How do we review brokers?
NerdWallet’s comprehensive review process evaluates and ranks the largest U.S. brokers by assets under management, along with emerging industry players. Our aim is to provide an independent assessment of providers to help arm you with information to make sound, informed judgements on which ones will best meet your needs. We adhere to strict guidelines for editorial integrity.
We collect data directly from providers through detailed questionnaires, and conduct first-hand testing and observation through provider demonstrations. The questionnaire answers, combined with demonstrations, interviews of personnel at the providers and our specialists’ hands-on research, fuel our proprietary assessment process that scores each provider’s performance across more than 20 factors. The final output produces star ratings from poor (one star) to excellent (five stars).
