Save your filter set once and rerun it each morning before the bell. Preset scans catch moves you would miss while typing.
What does Webull's free tier include?
Broker and screener in one app.
Webull free carries real-time US quotes, roughly fifty screener filters, and extended hours views. Options chains load fast for spreads practice.
Having scans and execution in one screen removes tab switching. That matters most for mobile-first traders.
The built-in screener covers price, volume, and performance filters with saved screens. Level one quotes stream free, and paper trading rounds out practice. For many first-year traders, Webull alone carries the whole morning routine.
Which day trading rules shape your screener setup?
Two FINRA rules trump every feature list.
| Rule | What it does | Your constraint |
|---|
| Pattern day trading | Flags 4+ day trades in 5 days on margin | $25,000 minimum equity |
| T+1 settlement | Cash trades settle next business day | No free riding on unsettled cash |
Cash accounts dodge the equity floor but must respect settled funds. Reusing unsettled cash too fast triggers good-faith violations (FINRA, 2026).
How do you match a screener to your trading style?
Style picks the tool, not the reverse.
| Style | Priority filter | Tool fit |
|---|
| Opening range breakouts | Gap % plus volume | Finviz premarket |
| Momentum continuation | Relative strength | TradingView scans |
| Small-cap volatility | Float and price range | Finviz plus broker L2 |
| Options day trades | High open interest | Webull chains |
Write your setup down before choosing software. The tool that fits your written plan wins. Test the scan across different market weeks too, because a filter tuned to one trend often dies in the next one.
What should you verify before relying on any free tier?
Free tools shift their limits without notice.
Check three things monthly: data freshness, alert caps, and exchange coverage. Delayed quotes poison live entries.
Cross-check one signal on a second platform during fast markets. Halts and stale after-hours prints fool scans weekly.
Risk rules matter more than any screener feature list. Traders carrying student debt should read our student loan debt statistics guide before sizing up positions. High-rate balances compound against you faster than any scan compounds for you.
Backtest your scan idea on at least three months of data. A filter that worked once is a coin flip wearing a suit.
What are the next steps to start scanning today?
Pick two tools and go deep.
Choose one chart tool and one filter tool from the table. Build a single morning scan for your exact setup. Paper trade that scan for two weeks before risking money.
Log every signal and outcome in a journal. Review the losers weekly and cut what fails. Broader finance skills compound too; our beginner finance courses roundup builds that base.
The best free stock screener for day trading is the one you know cold. Depth beats breadth every session.
