Summary: Best Online Trading Platforms for Day Trading



The best online brokers for day trading

These brokers are our best overall picks because of their competitive pricing and strong trading platforms and tools.

TD Ameritrade and Interactive Brokers have that powerful combination that every trader wants: Low commissions paired with advanced trading tools and platforms. Interactive Brokers may have an edge with traders who prefer per-share pricing and can meet the $10,000 account minimum and $10 monthly commission minimum — both of which docked the broker slightly in our star ratings. TD Ameritrade offers a very competitive flat rate and no minimum balance requirement. Both brokerages offer a very extensive investment selection, including futures options and forex trading, while Interactive Brokers also offers precious metals.

The best trading platforms

These brokers offer some of the most powerful trading platforms available, with no minimums or fees.  

Both top picks, TD Ameritrade and Interactive Brokers, have strong trading platforms. But TD Ameritrade also excels here, as does Charles Schwab. TD Ameritrade offers what may be the best trading platform available, thinkorswim, along with Trade Architect, a second platform designed for simplicity. Charles Schwab also offers two excellent platforms:, a Web platform suitable for beginners, and StreetSmart Edge, a more advanced option with elevated charting functionality. Both brokers make all of their tools and platforms available to all customers with no trade activity or balance minimums (taking into account Schwab’s easily avoidable $1,000 account minimum).

The best online brokers for options trading

These brokers offer the most competitive pricing and strongest tools for options traders.

OptionsXpress and TradeStation are both superior brokers for options traders, though their appeal depends largely on trade activity and platform needs. TradeStation is for seriously committed traders: The company’s platform — which is outstanding — comes with a $99.95 monthly fee, waived only for those who in the previous month carried a $100,000 account balance or traded at least 5,000 shares, 50 options contracts or 10 round-turn futures/futures option contracts. (Note: In March 2017 the company eliminated monthly service fees for its desktop, mobile and web-trading apps for non-professional subscribers on the per-trade pricing plan.) Active but low-volume options investors will probably prefer TradeStation’s per-share/per-contract commission schedule ($1 per option contract, no base or ticket charge, with a minimum one contract market or limit order). OptionsXpress offers similarly competitive commissions, though its trading platform isn’t as robust.

The online brokers with the lowest margin rates

Traders who utilize margin should prioritize a broker’s margin rates in their search.

Our top choice for best online broker wins here, too — in fact, no one comes close to Interactive Brokers when it comes to margin rates, so if that’s your No. 1 priority, you’ll likely find your home there. The broker charges a blended rate based on account balance, but features a calculator on its website to help investors quickly do the math. As noted above, Interactive Brokers does impose monthly trade minimums. EOption has a lower minimum deposit requirement and more reasonable trade requirements, charging a $50 inactivity fee only on accounts that haven’t traded at least twice in the past 12 months or have less than $10,000 in credit or debit balances. Both brokers charge very competitive commissions for stock and options trades.
