A stock screener filters thousands of listed companies down to the few that match your rules: price, market cap, valuation ratios, earnings growth, technical patterns, volume and more. The right choice depends on how you trade. For intraday scans and alerts, Trade Ideas is the platform built around streaming real-time setups. Swing traders who want fast visual scans of U.S. stocks fit Finviz; those who want every result on a full chart fit TradingView or TC2000. Long-term investors who need deep fundamental history fit Stock Rover, earnings-estimate investors fit Zacks, and TradingView is the only one of the seven here that screens beyond the U.S. and Canada. The sections below explain the features behind those differences and how to match a screener to your method before paying for a plan.

Key takeaways

• Market coverage is the sharpest dividing line. Among the seven platforms profiled below, only TradingView scans exchanges beyond the U.S. and Canada (150+ exchanges in 50+ countries).
• Data timing matters more than filter count for intraday trading. A scan built on delayed quotes can flag a move that has already played out.
• Backtesting is not universal. Seeking Alpha and TC2000 do not offer it as a dedicated feature; TradingView, Trade Ideas, Finviz, Stock Rover and Zacks do.
• Billing structures differ: Zacks and Seeking Alpha sell annual plans only, TC2000 has no free plan, and several others offer monthly plans with annual discounts.
• A free tier is enough for learning how screens work and for end-of-day research. Paid tiers mainly add real-time data, more criteria, alerts and testing tools.

What a Stock Screener Does

A screener is a database query with a friendly interface. You set conditions, and the tool returns every security that meets all of them at once. A simple screen might read: U.S.-listed stocks, market cap above $2 billion, price-to-earnings ratio below 20, revenue growth above 10% over the last year. The screener checks each company in its database against each rule and drops anything that fails one.

Most criteria fall into three groups:

• Fundamental filters use financial statement data and valuation: P/E and forward P/E, price-to-book, dividend yield, debt-to-equity, profit margins, revenue and earnings growth, return on equity, and analyst estimates.
• Technical filters use price and volume: moving averages and crossovers, relative strength index (RSI), new highs and lows, gaps, unusual volume, and chart patterns.
• Descriptive filters narrow the universe: exchange, country, sector, industry, market cap band, average daily volume, and share price.

Screeners and scanners overlap. A screener is usually run on demand, often on end-of-day data, while a scanner runs continuously during the session and pushes results or alerts as stocks start meeting your conditions. Day traders lean on scanners; long-term investors mostly use screeners. Several platforms below do both.

Two related functions appear on more advanced platforms. Alerts notify you when a stock enters or leaves your screen, or crosses a level you set. Backtesting runs a rule set against historical data to show how a strategy would have performed under the assumptions you give it.

What Separates One Screener From Another

Many platforms advertise hundreds of filters, so filter count alone rarely decides anything. These are the differences that change what you can actually do.

Market coverage

A screener can only find stocks in its database. A tool covering U.S. exchanges will never surface a company listed only in Frankfurt, Tokyo or Mumbai. If you invest internationally or want to compare, say, global chipmakers across listings, coverage outweighs every other feature. Coverage of U.S. and Canadian markets is common among dedicated screeners; broad global coverage is not.

Data timing

Screens built on end-of-day data are fine for investors who rebalance monthly or check ideas on weekends. Intraday traders need real-time data, and free quotes are often delayed, commonly by 15 minutes, which is long enough for a breakout or a gap fill to be over by the time the scan shows it. Real-time access is the term to confirm before subscribing: some platforms include real-time U.S. data only on paid tiers, some charge separately for feeds from specific exchanges, and availability can vary by market. Check whether the plan you are considering covers the exchanges you trade.

Depth of history

Fundamental investors care about how far back the financial data goes. Ten or twenty years of statements let you screen for companies that raised dividends through recessions, or that kept margins steady across cycles. A tool with only a few years of history can tell you a company looks cheap today, not whether it has always looked cheap.

Testing tools

Backtesting turns a screen into a hypothesis you can examine. Without it, you are judging rules by intuition or by the handful of current results. With it, you can see how often a rule set fired historically and what followed, under whatever assumptions about costs and execution the platform applies.

Charting and workflow

Swing and position traders usually move from a list of results to charts and back many times per session. A screener with integrated charts, multi-chart grids and watchlists saves that friction. A screener that exports a list you then paste into a separate charting tool works, but slowly.

Mobile access

Some specialized platforms are desktop- or browser-only. If you need to check scans or alerts away from a desk, confirm a mobile app exists. Trade Ideas and Finviz, for instance, do not offer one.

Pricing structure

Prices vary by more than a factor of ten across the field, and billing terms vary too. Monthly plans let you test a tool for a month; annual-only plans commit you to a year. Several providers discount annual billing, and some lock premium features (AI tools, real-time data, backtesting) behind their top tier.

How Seven Widely Used Screeners Differ

The profiles below cover seven dedicated screening platforms that frequently appear in comparisons, with each one’s plan prices, backtesting availability and market coverage. Prices change often, so confirm current terms on the provider’s site before subscribing.

TradingView

• Plans: limited free version; paid plans at $14.95, $34.95, $69.95 and $239.95 per month, with annual discounts
• Backtesting: yes
• Coverage: 150+ exchanges across 50+ countries

TradingView is primarily a charting platform with a full screener built in. Its distinguishing fact among these seven is coverage: it is the only one that scans markets outside the U.S. and Canada, which makes it the practical choice for anyone screening European, Asian or other international listings. The screener supports broad fundamental and technical criteria, including market cap filters, and users can build custom indicators and trading strategies in its scripting environment, then test them.

Its free tier is unusually capable, combining the screener with its charting and a large user community that publishes trade ideas and analysis. The limits show up as you scale: advanced features require a paid plan, some real-time market data costs extra on top of the subscription, and real-time availability varies by exchange.

Trade Ideas

• Plans: $0, $127 and $254 per month, with annual discounts
• Backtesting: yes
• Coverage: U.S. and Canadian markets

Trade Ideas is built for intraday trading. It runs real-time scans, streams potential setups as conditions change during the session, and uses AI-generated setups and analysis. It also includes a live trading room with commentary, brokerage integrations, customizable alerts and backtesting.

The trade-offs are significant. There is no mobile app, the learning curve is steep, and its premium features sit in the higher-priced plan. At the $254 monthly rate, a year costs $3,048 before any annual discount, so the platform makes the most sense for traders active enough to use its real-time features every session. Coverage is limited to U.S. and Canadian stocks.

Finviz

• Plans: $0 or $39.50 per month, with an annual discount
• Backtesting: yes
• Coverage: U.S. exchanges

Finviz is known for a fast, visual screening experience. Results can be viewed as lists, charts or heat maps, and its technical filters are extensive. The paid tier adds real-time data, alerts and multi-chart scanning, which suits swing traders who hold positions for several days to a few weeks and need to move quickly from a broad market scan to individual chart setups.

The free version is robust enough that many investors use it as their default research screener. Weaknesses: coverage is U.S.-only, fundamental depth trails platforms built around financial statements, and there is no mobile app.

Stock Rover

• Plans: $0, $34, $70, $99 and $199 per month, with annual discounts
• Backtesting: yes
• Coverage: U.S. and Canadian exchanges

Stock Rover is built around fundamental research. It offers up to 20 years of historical fundamentals, valuation screening, a scoring system for comparing companies, portfolio analysis tools and brokerage integrations for tracking actual holdings. That combination fits buy-and-hold investors who want to evaluate a company’s financial record over full business cycles rather than spot short-term setups.

It is less suited to day trading, leans more fundamental than technical, covers only U.S. and Canadian exchanges, and its upper plans are expensive relative to its entry tiers.

Zacks

• Plans: $0 or $249 per year (no monthly plan)
• Backtesting: yes, through its Pro Backtester
• Coverage: U.S. exchanges

Zacks centers its screening on earnings expectations. The Zacks Rank rating is based on revisions to analysts’ earnings estimates, on the premise that rising estimates tend to precede price strength. Its Earnings ESP (Expected Surprise Prediction) tool aims to flag companies more likely to report earnings above consensus. If your process revolves around estimate revisions and earnings season, these are features most screeners do not have.

The paid plan works out to about $20.75 per month if you divide the annual price by 12, but it must be paid as a year up front. The free version is solid. The technical criteria set is fairly small, the advanced tools take time to learn, and coverage is U.S.-focused.

Seeking Alpha

• Plans: $0, $299 or $2,400 per year (no monthly plans)
• Backtesting: no
• Coverage: U.S. exchanges

Seeking Alpha pairs conventional screening with analyst research and quantitative ratings. Its standout feature, Ask SA, lets you describe what you are looking for in plain language instead of building each filter by hand. That feature is available only in the $2,400 annual package, not in the $299 plan.

Natural-language tools speed up exploration, but AI-generated responses can be wrong or incomplete. The platform does not offer backtesting and is less oriented to technical trading.

TC2000

• Plans: no free plan; $24.99, $49.99 and $99.99 per month, with annual discounts
• Backtesting: no dedicated backtesting engine
• Coverage: U.S. and Canadian markets

TC2000 integrates screening, interactive charts, watchlists, customizable layouts and trading in one application, refined over a long product history. A trader can run a scan and immediately work through each result on a live chart without switching tools. It offers both technical and fundamental screening plus paper trading for practicing without real money.

It is the only one of these seven with no free plan, it lacks a dedicated backtesting engine, and advanced features require the higher tiers.

Choosing a Screener for Your Trading Style

Day trading

Day traders need a scanner that updates in real time, pushes alerts, and lets you filter on intraday conditions such as relative volume, gaps from the prior close, and new intraday highs or lows. Fundamentals matter far less. Among the platforms above, Trade Ideas is the one designed specifically around streaming intraday scans and AI-generated setups. TradingView and TC2000 also support active traders, especially those who want charts tightly linked to scans.

Day traders should also screen for tradability, not just movement. Minimum average volume and minimum price filters remove thinly traded stocks where wide bid-ask spreads can erase a small gain.

Swing trading

Swing traders typically screen after the close or before the open for stocks setting up over days or weeks: pullbacks to a moving average, breakouts above a prior range on rising volume, RSI recovering from oversold levels. End-of-day data is often sufficient, while strong technical filters and fast chart review matter a lot. Finviz fits this workflow well thanks to its visual results and multi-chart scanning; TradingView and TC2000 also suit traders who prefer to inspect every result on a full chart.

Long-term investing

Buy-and-hold investors screen on quality and valuation: steady revenue growth, consistent margins, manageable debt, reasonable valuation relative to history, and dividend records. Long data history is the key feature. Stock Rover’s up to 20 years of fundamentals and portfolio tools match this approach; Zacks suits investors whose process centers on earnings estimates; Seeking Alpha adds analyst research and quant ratings for investors who want written analysis alongside screens.

A long-term screen often starts broad. A useful baseline is to look at the largest companies in the world by market cap or the constituents of the S&P 500, then narrow by valuation and balance-sheet filters.

International investing

If you want to screen beyond U.S. and Canadian listings, the field narrows fast: of the seven platforms here, TradingView is the only one with global coverage.

Plain-language research

Investors who find filter menus tedious may prefer describing a screen in words. Seeking Alpha’s Ask SA does this, at its top annual price. The convenience comes with a verification step: confirm that the stocks returned actually meet the criteria you described.

Finviz vs. TradingView

These two are the most common starting points for self-directed traders, and the comparison is often framed as a choice when many people use both.

Coverage: TradingView scans 150+ exchanges in 50+ countries. Finviz covers U.S. exchanges only. For non-U.S. stocks, TradingView is the answer.

Screening style: Finviz is built for speed and visual scanning of the U.S. market, with heat maps and chart grids that let you review many results at a glance. TradingView’s screener sits inside a charting platform, so each result opens into a full chart with drawing tools and indicators.

Customization: TradingView lets users write custom indicators and strategies and test them. Finviz offers backtesting too, but its strength is the breadth of ready-made technical filters rather than custom code.

Pricing: Finviz has one paid tier at $39.50 per month. TradingView’s paid plans run from $14.95 to $239.95 per month, and some real-time exchange data costs extra. Both have usable free versions.

Mobile: TradingView has broad device support; Finviz has no mobile app.

A common pattern is to run broad U.S. scans in one tool and do chart work in the other. If you can only pick one and you trade U.S. stocks with a technical focus, the decision usually comes down to whether you value Finviz’s visual overview or TradingView’s charting depth.

Free Stock Screeners: What You Give Up

A free stock screener is a reasonable starting point. TradingView, Finviz, Stock Rover, Zacks, Seeking Alpha and Trade Ideas all offer a free tier. Free versions generally let you build screens on standard fundamental and technical criteria and review results, which covers a lot of long-term research.

What paid tiers typically add:

• Real-time data instead of delayed quotes
• More criteria, especially advanced technical conditions and deeper fundamental history
• Alerts when stocks enter or leave a screen
• Saved screens and more watchlists
• Backtesting or more extensive testing
• Proprietary tools such as AI-generated setups, natural-language search or rating systems

The upgrade question is practical: identify the specific feature you lack, then pay for the lowest tier that includes it.

Limits and Common Mistakes

Data errors and lags. Screeners rely on data vendors, and fundamentals update after filings, sometimes with delays or errors. A stock that passes a screen on stale data may no longer qualify. Verify key figures in the company’s filings before acting.

Overfitting a backtest. Adding rules until a backtest looks excellent usually produces a strategy tuned to past noise. Rules that are simple and make economic sense tend to be easier to trust than a dozen precise thresholds.

Ignoring costs and execution. A backtest that assumes fills at the closing price, with no commissions or slippage, overstates results, particularly for frequent trading in less liquid stocks.

Treating ratings as answers. Proprietary scores such as Zacks Rank or quant ratings are each platform’s own model. They summarize certain inputs; they do not replace understanding why a stock scores the way it does.

Mistaking a screen for a forecast. Screens describe current and historical conditions. A stock that meets a breakout condition today can reverse tomorrow.

FAQs

The Bottom Line

Traders and investors choosing a screener should start from their method: real-time scans for day trading, fast chart review for swing trading, long data history for long-term investing, and global coverage for international stocks. Free tiers handle learning and end-of-day research well. Upgrade only when you can name the feature you lack, pay for the lowest tier that includes it, and confirm current prices and data terms before subscribing.
