MarketSmith
IBD's MarketSurge/MarketSmith research platform for growth stock investors using CAN SLIM-style ratings, screens and chart pattern tools.
thinkorswim Scanner
Free professional-grade stock and options scanner bundled with Charles Schwab accounts, featuring ThinkScript customization, 400+ indicators, and real-time multi-market scanning.
Screener Head-to-Head
MarketSmith and thinkorswim target completely different trader profiles. MarketSmith ($149.95/month) is a methodology-driven platform built exclusively around CAN SLIM growth investing, with proprietary ratings and institutional sponsorship tracking that simplify decision-making within that framework. thinkorswim, completely free with any Schwab account, offers maximum flexibility: 400+ indicators, unlimited custom scan logic via ThinkScript, and options-specific tools (Option Hacker, Spread Hacker, Sizzle Index) for multi-market scanning across stocks, options, and futures.
The trade-off is strategy lock versus interface burden. MarketSmith confines you to US growth stocks and CAN SLIM doctrine—powerful for believers, worthless otherwise. thinkorswim unleashes you with 25-condition scans and custom scripting but demands weeks of study to navigate its dense, intimidating interface. MarketSmith includes backtesting and PaperMoney simulation; thinkorswim offers the same via PaperMoney's $100K virtual account.
Pick MarketSmith if you're a committed CAN SLIM investor willing to pay for guided stock selection. Choose thinkorswim if you trade options, use Schwab, demand cost-free scanning, or need custom automation. Cost alone ($149.95 versus free) wins for most active traders—unless CAN SLIM's proven methodology directly aligns with your strategy.
