Best online trading platforms in May 2025
If you’re looking to actively trade the markets, you’ll probably want to pay close attention to your broker’s trading platform. Unlike buy-and-hold investors who don’t need to get the best price every time out, active or short-term traders live and die by their ability to get a low price. So that’s why finding a broker with a top trading platform can be so important.

With its acquisition of TD Ameritrade, Schwab acquired the highly regarded thinkorswim trading platform, which is now the broker’s key platform and a big plus for active traders.

You’ll also get real-time news, earnings reports and other economic news, so you stay on top of the market. Plus, you’ll have immediate access to tools such as Real-time Analytics, which offers trading signals when a stock crosses key technical levels, and Trade Armor, which visualizes your trading opportunities. It all comes in a customizable layout, or you can opt for one of the preset layouts. And you’ll get Fidelity’s helpful and responsive customer service on top of it all.

Interactive Brokers
Overview
Interactive Brokers has long been popular with active traders, because of its good trade execution and ability to transact in almost any market. The broker’s GlobalTrader mobile platform gets the job done if you just need to make a quick trade, but traders will likely find the broker’s Trader Workstation to be a real workhorse. This fully featured platform seems to do it all: customizable charts, real-time data, streaming news, option analytics and more. Interactive Brokers offers a Pro tier with per-share pricing and a Lite tier with commission-free trading on stocks and ETFs. Either way, you get access to its top trading platforms – including the IMPACT mobile app that helps you sift through ESG investments – and you’ll also get discounts if you’re trading significant volume.
- Cost per stock/ETF trade: $0.005 per share, with $1 minimum for IBKR Pro, or free on Lite tier
- Cost per options trade: 65 cents per contract
E-Trade

Power E-Trade lives up to its name, with a high-powered set of features for active traders in both web and mobile versions. The broker’s flagship trading platform — Power E-Trade — is web-based and offers more than 100 technical studies and dozens of drawing tools to help traders analyze the markets. You’ll be able to overlay technical patterns on the charts to assess where the security may go in the future, calculate risk-reward and breakeven on options trades and look for unusual activity that might lead to an attractive opportunity. You’ll be able to see the risk-reward on options trades visually and the trading platform brings Bloomberg TV right onto your device. Plus, it doesn’t take a lot of options volume to secure a discounted rate, one of the best prices in the industry.

Other features include access to Nasdaq Level II quotes, more than 100 technical studies to help you analyze the trading action and charting tools that use streaming data.

Ally Invest
Overview
Ally Invest’s trading platform has a lot that active traders will like. You’ll easily be able to track stocks you’re interested in by creating watchlists and can monitor the profits and losses of your active positions. Eight different chart types are available, and you’ll have access to chart studies and drawing tools to help analyze trade ideas. There’s also a probability calculator that will assess how likely you are to meet your goals. The mobile app shouldn’t slow you down any and will help you keep trading even when you’re on the go. Like most of its competition, Ally doesn’t charge commissions for stock or ETF trades, but its commission on options trading is slightly below the industry standard.

Tastytrade
Overview
Tastytrade is designed for traders, and it shows in a variety of different ways, including the trading platform that arrives in web, desktop and mobile versions. You’ll get access to hundreds of indicators and charts, in-app research, watchlists and one of the more interesting features – a live “follow feed” that tracks a select range of tasty traders. You’ll be able to see their moves and trade alongside them if you like. Tastytrade's commission structure is attractive for traders as well. Of course, commissions on stocks and ETF are at the industry-standard of $0, but options cost $1 for a round-trip contract – so no incremental fee to close out a position – and they’re capped at $10 per leg per order. So 20, 30 or 40 basic contracts still cost you just $10.
- Cost per stock/ETF trade: $0
- Cost per options trade: $1 per round-trip contract, capped at $10 per leg per order
TradeStation
Overview
With volume discounts and powerful trading platforms, TradeStation should make it to a trader’s shortlist for potential brokers. The flagship desktop app provides a high-caliber experience, with built-in charting indicators, more than 180 technical and fundamental indicators, the ability to create your own indicators and decades of historical data for backtesting strategies. If you don’t quite need all that power but still want a highly capable app, you can opt for the broker’s web-based platform with streaming real-time quotes, dozens of technical studies, watchlists and plenty more.
- Cost per stock/ETF trade: $0
- Cost per options trade: 60 cents per contract
Bottom line
While active traders may focus primarily on a broker’s trading platform, that’s not the only consideration, of course. Traders should also consider what other kinds of value a broker can bring, including fundamental or technical research, costs including volume-based discounts and not least, customer support, which can help resolve any tricky problems along the way.
