The most platform you can get for zero dollars, provided you accept the learning curve and the scan lag.
thinkorswim scores 84 out of 100 across five pillars, 20 points each.
thinkorswim is the most capable free platform there is. It's also slow to scan, and the reason is structural: on Schwab's servers, scans sit behind real-time data in the queue. Build a scan below, run it, and watch what that costs during a fast open.
Simulated at 8x speed so you don't wait four real minutes. Schwab does not publish a scan refresh interval; timings here are modeled on user-reported 3 to 5 minute refresh windows, and your results vary with server load.
How the free thinkorswim scanner (Stock Hacker) works, its 25-filter setup, real cost, alerts, and where scan lag actually matters. Full 2026 breakdown.

Every Schwab client gets the full desktop, web and mobile suite for no platform fee, with no account minimum, $0 online equity commissions, over 400 technical studies, thinkScript for building your own indicators, paperMoney simulated trading on live data, and OnDemand market replay. Programmers and power users who know it deeply call it one of the most powerful retail platforms available, and 325,000+ App Store ratings averaging 4.7 back the community verdict of 18.
Usability scores 13 because the depth cuts both ways: new traders consistently describe the desktop platform as intimidating, and even loyal users say the look is showing its age. The sharper limit for day traders is Stock Hacker. Scans run on Schwab's servers, Schwab publishes no refresh interval, and experienced users report results lagging real-time charts by minutes at the busiest moments, which is exactly when a scanner matters most.

Where thinkorswim is the wrong spend.
A real complaint from the trading forums, and what this tool actually does about it.
“You'll NEVER get lightning fast scans during the standard trading day if the scans are large or complex...”
Source: useThinkScript forum
That is the trade-off in plain sight: scans run server-side and sit below quote delivery in priority, so complex scans during the open are slow by design. The workable answer is to keep intraday scans small and simple, lean on dynamic watchlists for monitoring, and treat Stock Hacker as a candidate finder for intraday and daily trends rather than a race-the-tape alert engine.
