If your edge depends on getting filled in the first 30 minutes on fast-moving stocks, DAS Trader Pro at a direct-access broker is the better tool, and it isn’t close. If you trade options, futures, or anything where a half-second doesn’t decide the trade, thinkorswim does more, costs nothing, and is easier to live with.
Choose DAS Trader if: you scalp or trade momentum in size, you need hotkey order entry, a Level 2 montage, locates for shorting, and a 4 a.m. premarket start, and you’re willing to pay $100–$200 a month plus per-share commissions for it.
Choose thinkorswim if: you trade options or futures, you hold positions longer than a few minutes, you want professional charting and a built-in simulator for free, or you’re not yet sure day trading is your thing.
There’s also a hybrid that looks tempting on paper: running DAS Trader on top of a Charles Schwab account. We’ll show you, from DAS’s own documentation, why that setup gives up most of what you’d be paying for.

Ratings follow the criteria on how we rate. The higher thinkorswim score reflects breadth and value; it does not mean thinkorswim wins the specific job DAS exists for, as the next sections show.
Execution and routing: where the comparison actually lives
Here’s the structural difference. DAS Trader at a first-party direct-access broker sends your order straight to the market venue you pick. You choose the route, you see the Level 2 book you’re hitting, and the platform was built around that workflow. DAS’s own supported-functions documentation states it plainly: direct access trading is supported only through its first-party broker network, and “if millisecond latency is an issue, you should consider using a first-party broker that sends orders from DAS directly to the market.”
Thinkorswim works differently. Orders go into Schwab’s routing process, which selects among exchanges and liquidity providers based on Schwab’s execution-quality monitoring. The results are genuinely good for a retail pipeline: per Schwab’s execution-quality disclosures, average execution speed was 0.05 seconds in Q1 2026, with 97% of orders receiving price improvement. For a position you’ll hold for hours, that’s excellent. You’re trading control for convenience, and at thinkorswim’s price the trade is free.
The stakes show up on thin, fast names. Say you’re trying to bail out of 1,000 shares of a low-float gapper that’s dropping a dime a second. Each tenth of a second of delay between your keypress and the fill is roughly $10; a full second is around $100, on one trade. A trader who exits fast movers daily can lose more to that lag in a month than DAS costs. A trader in SPY options will never notice it.
Winner: DAS Trader at a direct-access broker. For everyone else, Schwab’s routing is more than good enough, and it’s free.
The DAS-on-Schwab setup: the middle path that isn’t
You can subscribe to DAS directly and link it to a live Schwab account; non-professional packages run $100 to $200 per month depending on the data tier. The pitch is obvious: keep your Schwab account, get the DAS montage and hotkeys. The problem is what DAS’s own compatibility table (updated May 2026) says about how it works.
Every order placed through the Schwab connection travels through an API to Schwab, where Schwab processes and fills it. There is no direct access trading on that connection. DAS notes that “Schwab acknowledgement is above a second delay and so some hotkey orders may get rejected.” Several order tools are listed as unsupported via Schwab: IOC orders, at-open and at-close orders, AON, the short locate tool, futures, forex, and complex options. Premarket through the Schwab connection starts at 7 a.m. ET, against 4 a.m. on DAS first-party brokers.
So the hybrid buys you the DAS interface, real Level 2 data, and hotkey workflow, while the thing that justifies the category, fast direct fills, stays out of reach. If you mainly want the montage layout and TotalView on a Schwab account, the Deluxe tier at $150 a month delivers that. If you want DAS for speed, the only honest version is DAS at a direct-access broker from the DAS broker network.
Winner: nobody. This configuration is a charting-and-data upgrade, not an execution upgrade, and DAS says so itself.
Cost: zero versus a four-figure annual bill
Thinkorswim costs nothing beyond Schwab’s standard commissions: $0 on listed stocks and ETFs, $0.65 per options contract, $2.25 per futures contract, and $6.95 on OTC equities. No account minimum, no platform fee, no data fee.
DAS pricing direct from DAS runs $100 a month for basic Level 1 data, $150 for the Deluxe tier with NASDAQ TotalView, and $200 for Premium Elite with all books and imbalance data. That’s $1,200–$2,400 a year before you trade a share, and before broker commissions, which at direct-access firms are typically per-share with ECN pass-through fees rather than zero. One detail worth knowing: DAS’s 3, 6, and 12-month prepaid options cost exactly the monthly rate times the term. There is no prepay discount, so there’s no reason to lock up $1,800 in advance.
Billing terms are the category norm for market-data subscriptions, which is to say strict: all sales are final, no refunds on data or add-ons, with access running to the end of the paid period. Since prepaying saves nothing, start monthly, and treat the 14-day trial (first-time users only) as your real evaluation window.
Run the math on your own trading. If faster fills save you 3 cents per share on 2,000 shares a day, that’s $60 a day and the subscription pays for itself in three sessions. If you trade 400 shares twice a week, it never pays for itself.
Winner: thinkorswim, unless your size and frequency make the slippage math work, in which case the DAS bill is a cost of doing business.
Order entry and hotkeys
DAS is built around scripted hotkeys: buy the ask with a preset share size, send a stop at your risk level, cancel everything and flatten, all from single keystrokes, with a scripting language deep enough to compute share size from your stop distance. The montage puts Level 2, time and sales, and the order ticket in one window, and the March 2026 release added second-by-second ChartEx intervals. This is the workflow serious intraday equity traders standardize on, and it’s the reason the learning curve is real: expect days of setup and config before the platform feels fast.
Thinkorswim’s order entry is menu-and-click first, with thinkScript available for building custom studies and test logic. It’s far friendlier on day one, and the depth is in analysis rather than entry speed. Neither platform’s built-in scanning is its headline feature; traders hunting premarket gappers and momentum often run a dedicated scanner alongside either one, and our Trade Ideas review covers the tool most commonly paired with DAS for exactly that.
Winner: DAS Trader for entry speed, by design. Thinkorswim for anyone who’d rather analyze than script.
Charting, options, and breadth
Thinkorswim ships with 400+ technical studies, options analytics with probability and volatility modeling, what-if simulation on real and hypothetical trades, and live CNBC streaming. It trades stocks, ETFs, options, futures, and forex, including 24/5 trading on over 1,100 stocks and ETFs, and desktop installers exist for Windows, Mac, and Linux. As a complete trading workstation, it’s the deeper product, which is why it keeps winning desktop-platform awards.
DAS charts have closed real ground, with the standard study library, anchored VWAP, opening range, and the new seconds-interval charting. But charting is the supporting act; the montage is the show. Options trade on DAS, complex options too at first-party brokers, but a dedicated options trader gains nothing here for the money. Fractional shares are not supported on DAS, per its own function table.
Winner: thinkorswim, clearly.
Shorting and premarket
For short sellers in hard-to-borrow names, this section decides it. DAS at first-party brokers includes a short locate window: inquire across locate routes, compare prices, accept the cheapest borrow, with auto-locate scripting and per-symbol cost caps. DAS’s docs note the locate tool is not supported through the IB or Schwab connections, which is one more reason the first-party setup is the only real version. Premarket access starts at 4 a.m. ET, when gappers set their levels; see our premarket trading guide for why that window matters.
Thinkorswim shorts easy-to-borrow stocks fine, and its 24/5 session covers large caps overnight. But locates on hard-to-borrow small caps are not a retail-pipeline feature, and the difference between direct-access and retail brokers is widest exactly here.
Winner: DAS Trader, decisively, for short-biased small-cap traders.
Practice and trial
Thinkorswim wins the on-ramp. paperMoney is built into every thinkorswim platform with real-time simulated trading, and a 30-day Guest Pass works without even opening an account. Schwab requires no minimum to open and the platform stays free after.
DAS offers a 14-day trial to first-time users and a standalone real-time simulator from $100 a month, the only environment where market replay runs anytime; on live setups, replay is limited to non-market hours. Paying $100 a month to practice is steep, but replaying the open at night is a genuinely useful training tool the free option doesn’t match.
Winner: thinkorswim for free practice; DAS if replay-based training is worth a subscription to you.
Verdict: match the platform to the trade, not the hype
There is no universal winner here because the two products aren’t really competing for the same trader. Thinkorswim is the better platform for most people who’d ask the question: free, deep, multi-asset, with the best practice environment in the business. DAS Trader is the better tool for a narrower trader who already knows who they are: intraday equity traders, often short-biased, trading enough size and frequency that fill quality is measured in dollars per day, running it at a direct-access broker where the speed actually exists.
And skip the middle path. Layering DAS on a Schwab account costs DAS money for thinkorswim-style execution; DAS’s own documentation is candid that the speed lives with its first-party brokers. Pick a side based on how you actually trade, then read the full DAS Trader review or the full thinkorswim review for the deeper look.
FAQ
Can you use DAS Trader Pro with a Charles Schwab account?
Yes. You subscribe directly with DAS first ($100–$200 a month for non-professional data tiers), then authorize the link to Schwab. Orders travel through an API to Schwab, which fills them on its standard commission schedule. DAS’s documentation notes acknowledgment runs above a second on this connection and that direct access trading, IOC orders, and the short locate tool are not supported through it.
Is DAS Trader faster than thinkorswim?
At a first-party direct-access broker, yes: DAS sends orders directly to your chosen market venue, and the platform is built for hotkey-speed entry. Thinkorswim orders go through Schwab’s routing process, which averaged 0.05 seconds execution speed in Q1 2026 per Schwab’s disclosures. Layered on top of a Schwab account, DAS loses the speed advantage, by DAS’s own account.
How much does DAS Trader Pro cost?
Direct from DAS, non-professional packages run $100 a month (basic Level 1) to $200 a month (all books, imbalance, float data), with add-ons like the Trade Signal scanner at $35 a month. Prepaid terms carry no discount, all sales are final, and a 14-day trial is available to first-time users only. Pricing through a DAS-network broker varies by firm.
Is thinkorswim really free?
For Schwab clients, yes. There’s no platform fee, no data fee, and no account minimum to open. Standard commissions apply to trades: $0 on listed stocks and ETFs, $0.65 per options contract, $2.25 per futures contract, and $6.95 on OTC equities.
Which is better for shorting low-float stocks?
DAS Trader at a direct-access broker. Its short locate window lets you price and accept borrows across multiple locate routes before you hit the sell button, and premarket access starts at 4 a.m. ET. The locate tool is not available through the IB or Schwab connections, so the broker choice is part of the answer.
