What is the best free stock screener?

Finviz is the best free stock screener for most traders. It offers 70+ filters, instant results, a sector heat map, chart pattern recognition, and insider tracking — all completely free with delayed data. For options traders, thinkorswim takes the top spot with IV rank and delta filters. TradingView is best if you trade crypto, forex, or futures.

Is thinkorswim screener actually free?

Yes. thinkorswim (now owned by Charles Schwab) provides its full screener with real-time data to anyone with a Schwab brokerage account. No monthly fee for the platform or its scanning features. You can use the thinkScript language to write fully custom scans at no cost.

Does TradingView have a stock screener?

Yes. TradingView has a built-in screener accessible at tradingview.com/screener. It covers stocks, crypto, forex, and futures. The free tier allows filtering on ~50 criteria with a 15-minute data delay for US stocks. Its biggest advantage over Finviz is multi-asset coverage and one-click access to interactive charts.

Can I use all three screeners together?

Yes, and many serious traders do. A common workflow: use Finviz pre-market to find gap plays, then analyze those stocks on TradingView for chart confirmation. Use thinkorswim's scanner if you trade options and need IV rank or delta-based filters. There is no conflict between using all three.

TradingView Screener — Best for Multi-Asset Traders

tradingview.com/screener — Free

TradingView's screener isn't the most powerful filter-by-filter, but it has one huge advantage neither competitor can touch: it covers stocks, crypto, forex, futures, and indices all in one place. If you trade anything other than US stocks, this is your screener.

The other advantage is workflow integration. When you find a stock in TradingView's screener, clicking it opens an interactive chart instantly — with your saved indicators already applied. No copying and pasting tickers into another tool. The friction from find to chart is essentially zero.

Unique advantages

Only free screener covering crypto, forex, and futures
One-click from screener result to interactive chart
Technical Ratings column (buy/sell/neutral AI summary)
Mobile screener via app — works well on iOS and Android
CSV export on free plan (Finviz charges for this)

Real limitations

~50 filters vs Finviz's 70+ — no float, no chart pattern, no insider
No sector heat map comparable to Finviz
Results refresh slower — not instant like Finviz
US stock data delayed 15 minutes on free plan
No fundamental depth (P/B, PEG, debt/equity, etc.)

Best Use for TradingView Screener

Use it as the bridge between screening and analysis. After running a Finviz scan pre-market, pull the shortlist into TradingView for chart review. Or use it exclusively when you trade crypto, forex, or futures — the two alternatives cover US stocks only.

thinkorswim — Best Free Screener for Options Traders

thinkorswim by Schwab — Free (requires account)

thinkorswim (ToS) is the most powerful free screener on this list — but it requires a Charles Schwab brokerage account to access. Opening the account is free, no minimum balance required, and the full platform including real-time data is included at no cost.

Why thinkorswim is the only free options screener worth using

Neither Finviz nor TradingView offers options-specific scan criteria. thinkorswim lets you scan for stocks by IV rank (so you know implied volatility is elevated before selling premium), delta range, open interest, days to expiration, and more. For options traders, this is irreplaceable — and it's completely free.

thinkScript: The Free Custom Scan Language

thinkorswim uses a proprietary scripting language called thinkScript to build custom scan conditions. If you can read basic code logic, you can write scans that don't exist anywhere else. Here are three examples:

Pre-Market Gap Scanner

thinkScript

close is not NaN
volume(period: AggregationPeriod.DAY) > 500000
close / close[1] - 1 > .03

Finds stocks gapping up 3%+ with volume above 500K

IV Rank > 50 (Options)

thinkScript

IV_Percentile() > 50
volume(period: AggregationPeriod.DAY) > 200000

Finds optionable stocks with elevated implied volatility

RVOL > 2.0

thinkScript

volume > 2 * Average(volume, 20)

Classic relative volume scan — 2x the 20-day average

Unique advantages

Free real-time data — no 15-minute delay
IV rank and IV percentile filter (options-essential)
Delta, gamma, open interest scan criteria
thinkScript custom conditions — unlimited flexibility
Direct execution: scan result to order in one click
Paper trading integration for strategy testing

Real limitations

Requires opening a Schwab brokerage account
Steep learning curve — interface is complex
No sector heat map
Mobile app scanner is limited vs desktop
No chart pattern screener
Primarily US stocks only

Can You Use All Three?

Yes — and many experienced traders do. They serve different jobs and don't overlap in any meaningful way. Here's how a complete free-tools workflow looks when all three are in play:

Step 1Finviz

Pre-market: Find your watch list

Run the gap + RVOL + float scan. In 30 seconds you have a shortlist of 5–15 names with the day's highest potential. Also check the heat map for sector bias.

Step 2thinkorswim

Options scan: Find premium-selling candidates

Run the IV rank > 50 scan. Separately from your day-trading watch list, this gives you stocks with elevated implied volatility — candidates for selling calls, puts, or iron condors.

Step 3TradingView

Session: Analyze, alert, and trade

Load your Finviz shortlist on TradingView charts. Set alerts at key levels. Monitor real-time price action. If using crypto or forex, run your own separate screener pass directly in TradingView.

Total cost of this stack: $0. All three tools are free. You need a Schwab account for thinkorswim (no minimum balance) and that's it. This is a legitimately institutional-grade research workflow at zero monthly cost.

Final Verdict

The Verdict in Three Sentences

Stock day traders and swing traders: Start with Finviz. It's the most powerful free screener for US stocks with zero friction. Add TradingView for chart analysis and you have a complete free stack.

Options traders: Open a Schwab account and use thinkorswim. IV rank filtering alone makes it irreplaceable — nothing else on this list has it for free.

Crypto, forex, or futures traders: TradingView screener. It's the only one covering these asset classes.
