Stock scanners and screeners help traders search the market for stocks that match specific criteria such as price, volume, relative volume, momentum, technical conditions, and market activity. We use scanners to help find potential trade setups, narrow our watchlists, and spend less time manually searching through thousands of stocks.
A scanner is a discovery tool, not a trading signal. Once a stock appears on a scan, we still pull up the chart, look at price action and volume, identify support and resistance, and decide whether the setup fits our strategy and risk.
Below are some of the stock scanners and screeners we use or have reviewed, along with the types of traders each one may fit best.
Best Stock Scanners for 2026
We compared popular stock scanners and screeners based on scanning features, market data, customization, charting, news, research tools, and the types of traders they are built for.
Stock Scanners Overview
Trade Ideas
Overview
We primarily use Trade Ideas to find stocks worth putting on our radar. It is especially useful for momentum stocks, morning gappers, unusual volume, premarket movers, high-of-day activity, and potential breakout setups.
The Channel Bar includes prebuilt scans for areas such as momentum, biotech, volume, penny stocks, options, and premarket activity. You can also build custom scans around the exact criteria you trade.
The important part is what happens after the scan. A stock appearing in Trade Ideas does not mean we automatically enter it. We still review the chart, look at the setup and location, and decide whether the trade makes sense.
FinViz
Overview
FinViz is useful when you want to combine several filters without needing a dedicated real-time scanner. You can screen for relative volume, market capitalization, RSI, moving averages, valuation metrics, price performance, and many other factors.
We also use FinViz for some specific scans, including our pinch play scanner.
The heat map is another feature we like because it gives you a quick visual look at which sectors and stocks are showing strength or weakness.
For traders who are just getting started, FinViz is one of the better places to learn how screening works without immediately paying for a more advanced platform.
Thinkorswim
Overview
One of the biggest advantages of Thinkorswim is that you can scan for a stock and then immediately pull up the chart without moving to another platform.
You can use existing scans or build your own using price, volume, technical, fundamental, and other criteria. That makes it useful for traders who want scanning and charting together instead of paying for separate tools.
For beginners, Thinkorswim can also be a good place to figure out which scanner features you actually use before spending money on a dedicated real-time scanning service.
TrendSpider
Overview
TrendSpider is especially useful if your scanning process is based on technical conditions. You can search for candlestick patterns, indicators, price relationships, and combinations of criteria.
For example, you can look for a particular candlestick pattern while RSI, price, or another indicator also meets your conditions.
It also includes automated trendlines, Fibonacci levels, multi-factor alerts, and backtesting. Those tools can save time, but we still want to look at the chart ourselves before making a trading decision.
Benzinga Pro
Overview
We like Benzinga Pro when we want to know not only that a stock is moving, but also why it is moving. Earnings, company announcements, analyst changes, economic news, and other catalysts can create the volatility traders are looking for.
One of our favorite features is Squawk, which reads breaking market news aloud. That lets you keep watching charts while still hearing important headlines as they come out.
Its scanner can also filter stocks by price, volume, market capitalization, and other criteria. The combination of scanning and real-time news is what makes Benzinga Pro different from a scanner focused only on price and volume.
Stock Rover
Overview
You can screen and compare companies using valuation, profitability, growth, financial strength, and other fundamental metrics.
That makes Stock Rover different from platforms such as Trade Ideas that are primarily built around real-time price and volume activity.
We think it makes the most sense for swing traders and investors who want to research the business behind the stock as part of their process.
How Do You Use a Stock Scanner?
Stock scanners help narrow thousands of stocks down to a smaller group that matches the criteria you care about. You can build scans around price, volume, technical conditions, momentum, volatility, fundamentals, or specific trading setups.
We usually think of the scanner as the beginning of the process. Once a stock appears, we pull up the chart and ask why it showed up. Is volume unusually high? Is there a catalyst? Is price approaching support or resistance? Is there actually a setup, or is the stock simply moving?
Scanners are useful trading tools, but finding a stock is only the first step. You still need to evaluate the chart, understand the setup, define your risk, and make your own trading decision.
We also show members how we use scanners to find stocks and potential setups during live streams in our trade rooms.
What Is the Difference Between a Stock Scanner and Stock Screener?
Stock scanners and stock screeners both help you find stocks that meet specific criteria, but they are often used differently.
A stock scanner typically monitors market activity and continually looks for stocks meeting certain conditions. Active traders often use scanners to find unusual volume, momentum, price moves, breakouts, and other technical setups as they develop.
A stock screener is commonly used to filter stocks using technical, fundamental, or descriptive criteria such as market capitalization, valuation, earnings, volume, price performance, and financial metrics.
The terms are often used interchangeably because many modern trading platforms include both scanning and screening features. Popular screeners include Morningstar, Zacks, and TradingView.
Final Thoughts on Stock Scanners
Stock scanners and screeners can save a lot of time by helping you find stocks that match the criteria you actually trade. The right tool depends on whether you are looking for real-time momentum, technical setups, fundamental data, news, or a combination of those things.
Active traders may care more about real-time price, volume, momentum, and news. Swing traders may focus more on technical setups and alerts, while investors may prefer screeners built around financial and fundamental data.
The scanner should help you find the opportunity, not make the decision for you. You still need to read the chart, understand why the stock is moving, determine whether the setup fits your strategy, and manage the risk yourself.
Learning how to use scanners becomes much more useful once you understand what you are actually looking for. Our trading courses cover the charting, technical analysis, and trading concepts that help you turn scanner results into something you can evaluate for yourself.

Look for a stock scanner that lets you filter the market using criteria that match your trading strategy. Depending on how you trade, that may include price, volume, relative volume, momentum, technical indicators, market capitalization, news, or fundamental data.
The best scanner is not necessarily the one with the most features. It is the one that helps you find the types of stocks and setups you actually trade.
No. A stock scanner finds stocks that meet the criteria you set. It does not determine whether a trade is good or whether you should buy or sell.
After a stock appears on your scanner, review the chart, understand why the stock was identified, determine whether it fits your strategy, and manage your risk before making a trading decision.
