Best Stock Broker for Day Trading

October 2, 2018 — 4:36 PM EDT

When choosing an online broker, day traders place a premium on speed, reliability, and low cost. Features designed to appeal to long-term infrequent traders are unnecessary for day traders, who generally start a trading day with no positions in their portfolios, make a lot of transactions, and end the day having closed all of those trades.

Day traders may place their trades manually, often from a chart, or set up an automated system which generates orders on their behalf.  Fundamental data is not a concern, but the ability to monitor price volatility, liquidity, trading volume, and breaking news is key. 

Day traders often prefer brokers who charge per share (rather than per trade).  They also need real-time margin and buying power updates. Each broker ranked here affords their day-trading customers the ability to enter orders very quickly by customizing the size of trades and turning off the trade confirmation screen.  We sought brokers who allow traders to place multiple orders simultaneously, designate which trading venue will handle the order, and customize trading defaults.

This ranking focuses on online brokers and does not consider proprietary trading shops.

The longtime leader in low-cost trading, Interactive Brokers is geared for very active traders. Though they have been adding features for less frequent traders over the last few years, their priority is keeping fees down. The speedy downloadable platform, Trader Workstation (TWS), includes dozens of professional-grade trading algorithms, such as the Adaptive Algo, which finds better prices for filling orders. You can customize the algorithm to fill your market order at the midpoint between bid and ask, thereby seeking opportunities within the spread to chisel a fraction of a penny more for your profits.

IB’s margin rates are practically the lowest you will find, especially for traders who use more than $100,000 of margin. You can automate a trading strategy using an API plug-in, or by subscribing to a strategy on their Investors’ Marketplace.

Tastyworks is a fast, reliable platform focused on options analysis and trading, but there are also plenty of tools for stock/ETF traders. The dashboard layout is easily customizable. Unlike other brokers, the browser platform has almost every feature as the downloadable one -- key for those who aren’t always at home base. Even the mobile apps are power-packed. 

The tools are designed for people who visualize prospective trades rather than following a flow of time and sales data. They focus on liquidity, volatility, and the probability of a profit.  On quote pages, implied volatility appears before a quote in order to help customers understand market opportunity.

❌  Cons

•  Innovative pricing structure results in fairly low costs, especially when trading options.   •  Commissions are fixed. There’s no negotiating for a more active trader.

•  Scanners help you find securities that are becoming more volatile.   •  Cannot place multiple orders simultaneously, or stage orders for a later entry.
•  Watchlists are sortable by up to 50 data points.

Are You a Day Trader?

The most important considerations for most day traders are commissionsmargin rates, and other expenses associated with trading. Even if a day trader can consistently beat the market, the profit from those positions must exceed the cost of commissions, and for a high volume trader commission costs can easily run into the hundreds or thousands of dollars per day. Traders can check these rates by contacting the broker or checking the broker website, but most offer special rates for highly active day traders.

The next consideration for day traders is trading platform quality, which can impact things such as execution speed and price quotes. In an environment where high-frequency traders are buying and selling shares in milliseconds, human traders must be aware of and possess the best tools. Most brokers offer real-time execution, but slippage remains a concern, and traders should always test for themselves how long a platform takes to execute a trade.

It’s also important for day traders to consider factors like customer service and the broker’s financial stability. Customer service plays a key role during times of crisis – such as a computer crash or other failure when you need to reach support to place a trade. The best brokers offer dedicated account representatives for highly active day traders to assist in this regard. 

The financial strength of the firm is also important since small brokerages can and do go out of business, which can lead to a loss of your account.
