Their systems are stable and remain available during market surges. Technical analysis and statistical modeling of trading strategies is another strength of the TradeStation platform, which we ranked 4th overall. You can develop your own automatic trading system using the analysis tools and strategy backtesting. You can also generate income through the fully-paid stock lending program and enhance your trading skills with the extensive educational offerings.

Trade Experience

TradeStation Today is the first screen you'll see after logging into either the downloadable platform or the web platform, which includes featured videos, links to workspaces, the firm's Twitter feed and an economic calendar. The desktop platform, which is a downloadable app, is extensively customizable; the web platform has most of the TradeStation toolset and is a little easier to use. All data streams in real time. You can place, modify, and cancel trades from charts or by using keyboard shortcuts. TradeStation’s trade ticket is called Matrix, and it adapts to the asset class you’re trading. Hovering your mouse over a bid or ask price opens a trade ticket, which you can then modify prior to sending the order. Their orders are routed to seek out and capture as much price improvement and hidden size as reasonably possible within a reasonable period of time while being mindful of market impact.

The Traders Workstation is IB’s flagship platform, but you can also log into the web-based Client Portal to access portfolio analysis, a forum for clients, the Market Overview tool and other tools including trading. Several high-end analytical tools have been added to Client Portal, including scanners, global data, and customizable watchlists. There is streaming data everywhere on all platforms, though you can only have data updating on one device at a time. You can also enter orders from a graph, or from the matrix display in TWS. IB’s order execution engine has what could be the smartest order router in the business, as it stays on top of changes in market conditions to re-route all or parts of your order to achieve optimal execution, attain price improvement, and maximize any possible rebate.

TradeStation gives customers the choice of several different pricing tables, depending which assets and how frequently you trade. A standard trade of 500 shares is $5. If you trade frequently in small blocks, you might consider per-share pricing, which starts at $0.01 per share. Options transactions are near the average for the brokers we reviewed, while margin rates are slightly above average until you get up into 7 figures.

Interactive Brokers is one of the least expensive places to trade online. Clients can choose from a fixed rate plan or a tiered plan, depending on trading volume. The fixed rate plan is best for occasional traders who favor market orders, while the tiered model minimizes trading costs for frequent traders who factor exchange rebates into their strategies. We used the fixed rate plan for our calculations, which is $.005 per share with a minimum of $1 per trade. There is no per-leg fee for options trades; commissions range from a maximum of $0.70 per contract to $0.15 per contract depending on volume. Margin rates were the lowest in our survey, and you can borrow against your assets for any reason – not just trading. Plus, IB pays 1.7% on idle cash over $10,000.

Investopedia’s mission is to provide investors with unbiased, comprehensive reviews and ratings of online brokers. Our reviews are the result of six months of evaluating all aspects of an online broker’s platform, including the user experience, the quality of trade executions, the products available on their platforms, costs and fees, security, the mobile experience and customer service. We established a rating scale based on our criteria, collecting over 3,000 data points that we weighed into our star scoring system.

In addition, every broker we surveyed was required to fill out a 320-point survey about all aspects of their platform that we used in our testing. Many of the online brokers we evaluated provided us with in-person demonstrations of their platforms at our offices.

Our team of industry experts, led by Theresa W. Carey, conducted our reviews and developed this best-in-industry methodology for ranking online investing platforms for users at all levels. Click here to read our full methodology.
