DAS Trader and thinkorswim are both capable trading platforms, but they serve different types of traders.
DAS Trader is built for active traders who care about execution speed, hotkeys, Level II, direct routing, and short-selling workflows. thinkorswim is a broader platform built around charting, options analysis, scanning, education, and paper trading.
For most newer traders, thinkorswim is the simpler choice. For active small-cap traders who need more control over execution, DAS Trader may be worth the added cost and learning curve.

DAS Trader: Better for execution-focused traders
DAS Trader is designed around the needs of active day traders, especially people trading fast-moving equities.
Its main tools include Montage order entry, Level II, time and sales, hotkeys, order templates, routing controls, and short-locate tools. That makes it popular with small-cap momentum traders, scalpers, and traders who need to enter and exit positions quickly.
The important detail is that DAS features depend on your broker connection.
DAS says direct-access trading is available through its first-party broker network. If you connect DAS through Interactive Brokers or Charles Schwab, orders are sent through a gateway or API and handled by that broker. The experience is not identical.
DAS can also be useful for traders who short volatile stocks. Its Short Locate Tool is available through supported broker connections, which matters when hard-to-borrow shares are part of your strategy.
Choose DAS Trader if you need:
Fast hotkey and order-template workflows
Level II, time and sales, and Montage-based trading
Direct-access routing through a supported broker
Short-locate tools
A platform built around active equity execution
DAS is not the best choice just because it looks professional. It is worth considering only if your strategy actually depends on the tools it provides.
thinkorswim: Better for charts, options, and practice
thinkorswim is Schwab’s trading platform suite, available on desktop, web, and mobile.
It is the better all-around platform for traders who want strong charting, scanners, alerts, technical studies, education, and access to multiple markets. Schwab lists support for stocks, ETFs, options, futures, and forex through thinkorswim.
The desktop platform includes hundreds of indicators, studies, and drawing tools. That makes it a better fit for traders who spend more time analyzing setups than managing route-level execution.
thinkorswim also includes paperMoney, its simulated trading environment. Schwab says paperMoney gives users $100,000 in virtual buying power and supports simulated trading with real-time market data.
Paper trading will not prepare you for every part of live trading. It cannot recreate slippage, partial fills, hesitation, or the urge to revenge trade after a loss. But it is useful for learning order types, testing layouts, and building a repeatable process before risking capital.
Choose thinkorswim if you need:
No separate platform fee as a Schwab client
Advanced charting and technical analysis
Paper trading with real-time data
Options tools and multi-leg strategy support
Stocks, options, futures, and forex in one ecosystem
Desktop, web, and mobile access
Fees: Which platform is cheaper?
thinkorswim is usually cheaper to start with.
Schwab provides thinkorswim to clients with no platform fee. Schwab currently lists $0 online commissions for listed equity trades and $0.65 per options contract, although other fees can apply.
DAS costs vary by broker, market-data package, simulator access, and platform subscription. Before subscribing, calculate the full monthly cost, including market data and any locate fees.
If you are still learning a strategy, paying extra for an execution platform usually does not make sense. Better tools cannot fix poor risk management, oversized positions, or inconsistent setups.
The verdict
Choose DAS Trader if you actively trade equities and need execution tools such as hotkeys, routing, Level II, short locates, and a fast Montage workflow.
Choose thinkorswim if you want a lower-friction platform with stronger charting, paper trading, options tools, education, and access to multiple markets.
For most traders, thinkorswim is the better starting point. For dedicated small-cap traders whose process depends on execution and short-selling tools, DAS Trader can be the better fit.
