The Best Apps for Stock Patterns in 2026

The best app for stock patterns depends on which half of the job you want automated. TradingView draws patterns on the chart you are watching, and its built-in Auto Chart Patterns feature just left beta and moved behind the Premium plan. TrendSpider finds patterns across the whole market and backtests them, for a price that only makes sense if you trade actively. Thinkorswim and Webull both detect patterns for free inside a broker platform. Finviz screens thousands of stocks for head and shoulders and wedges without charging anything, and Patternz does full pattern recognition on your desktop for nothing at all. This comparison covers what each one actually detects, what it costs, and the part every scanner skips: whether the pattern is worth trading.

Quick comparison

What "detecting stock patterns" actually means

Pattern detection is three different jobs, and most disappointment with these apps comes from buying the wrong one.

The first job is drawing patterns on a chart you are already watching. TradingView, thinkorswim, and Webull do this: open a chart, switch the feature on, and the software outlines the wedge or the double bottom it finds in the visible price history. Useful for confirming what your eye suspects, useless for finding candidates you were not already looking at.

The second job is scanning the market. TrendSpider, Finviz, Trade Ideas, and Tickeron work through thousands of symbols and return the ones forming a specific pattern right now. This is the job people usually mean when they ask for a pattern app, and it is where an engineer on r/swingtrading landed when he explained why he built his own scanner: manually flipping through charts took so long that by the time he found a good pattern, it had already moved.

The third job is reading a single chart cold: you have a screenshot from a broker app, a Discord, or a group chat, and you want to know what the structure is. That is what Quant AI does, and it is a different tool from a scanner in the same way a translator is a different tool from a search engine.

Decide which job you need before comparing prices. Plenty of traders need two of the three; almost nobody needs all of them from one app.

TradingView: auto patterns on the chart, now behind Premium

TradingView is where most retail traders already chart, so its pattern detection matters more than anyone else's. The built-in Auto Chart Patterns indicators spent a long stretch in open beta, and that beta formally ended this summer: the feature now requires the Premium plan. If you were using it on a cheaper tier during the beta, that door has closed.

What you get for it is a set of indicators covering the classic formations: bullish and bearish flags, pennants, rectangles, rising and falling wedges, ascending and descending triangles, double and triple tops and bottoms, head and shoulders and its inverse, and Elliott wave counts. Each indicator scans the most recent 600 bars of the chart and draws both completed patterns and ones still in progress, so you can watch a head and shoulders forming while the neckline still holds. The 600-bar window is a real limit: on a daily chart that is roughly two and a half years, but on a weekly chart it reaches back further than most patterns stay relevant, and if you need older history you are into Bar Replay territory.

Two honest caveats. First, detection stays on the chart in front of you. TradingView will outline the wedge on the symbol you opened; it will not sweep the S&P 500 and hand you every wedge that exists today (pattern screening across symbols is script territory). Second, the community script library partly fills both gaps: independent developers publish auto-pattern indicators and multi-symbol pattern screeners, in free and paid flavors, and one tested roundup of free TradingView indicators rated the automated chart pattern algorithms among the best support and resistance tools on the platform. Quality varies script to script, so read the reviews under each one before trusting it with entries.

TradingView is the right answer if you live on its charts anyway and want patterns marked in place. It is the wrong answer if the thing you actually want is a market-wide pattern scan, which is the next app's whole business.

TrendSpider: the deepest automation, at the steepest price

TrendSpider automates more of technical analysis than anything else in this comparison. Its trademark feature is automated trendline detection: the software plots the trendlines itself and flags the ones with the best backtested success rate, which quietly answers the "did I draw that line right?" doubt that hangs over hand-drawn analysis. On top of that it recognizes more than 40 candlestick types and paints classic chart patterns directly onto the chart.

Two design choices separate it from TradingView's approach. TrendSpider's pattern engine focuses on live, actionable patterns: it discards formations that price has stopped respecting, which keeps the chart clear of dead history. And detection reaches past the open chart. The scanner runs pattern logic across whole universes, so a query like "every Russell 2000 stock with a descending triangle on the daily" is a supported, single-step workflow. Its newer scanners take plain-language criteria and build the scan for you, and the same platform folds in backtesting, so a flagged pattern can be tested against history before money touches it.

The catch is cost. TrendSpider is a paid platform with no free tier, and reviewers keep reaching the same verdict from different directions: it is worth it if it replaces two or three tools you would otherwise pay for separately (a charting platform, a scanner, a backtester), and hard to justify if you chart twice a week. One review this summer put it plainly: worth it for traders who want a feature-dense all-in-one platform and are comfortable with the price. If you are not sure you will use the scanning and backtesting layers, start cheaper and graduate.

thinkorswim: free pattern detection with a learning curve

Thinkorswim, Schwab's trading platform, hides a genuinely capable pattern engine behind its intimidating interface, and it costs nothing beyond having a Schwab account. Open the Patterns menu on any chart, tick Show Patterns, and the platform recognizes both candlestick patterns and classic chart formations in place. The candlestick list covers the standard set (hammers, dojis, engulfing patterns, and the rest), and each pattern can be tuned: calculation inputs, colors, and how the projected price range displays.

The feature that earns thinkorswim its place here is the Candlestick Pattern Editor. If you have a specific bar sequence you trade, you can define it yourself and have the platform mark every occurrence, which is something neither TradingView nor Webull offers at any price. Combined with thinkorswim's scanner (which handles technical conditions across the market), a patient user can rebuild much of what paid pattern platforms sell.

The cost is time. Thinkorswim is a professional-grade desktop platform, and pattern detection is buried a few menus deep in an interface built for people who use it all day. If you already bank at Schwab or want the deepest free option and are willing to spend an evening learning it, this is the best value on the page. If you want patterns flagged on your phone with zero setup, it is the wrong temperament.

Webull: free pattern signals where beginners already are

Webull ships pattern recognition as part of its free charting, under the label of technical signals: 28 classic chart patterns and 22 candlestick patterns, marked on the chart as they form, alongside 13 indicator-based signals. For a free broker app, that coverage is broad, and it extends into the screener, which can filter the market for stocks currently printing a specific candlestick pattern. That combination answers a question that comes up on trading forums verbatim: is there any chart scanner that can identify a stock based on a specific candle? On Webull, yes, free.

The honest limits: signals are flags, and Webull grades them lightly if at all. A marked "double bottom" means the geometry matched, and nothing about whether volume confirmed it, whether it formed at a level that matters, or how often that signal has worked on that symbol. Webull also stops at detection; there is no backtesting layer to check a signal's track record, which is exactly the layer TrendSpider charges for. Treat Webull's pattern signals as a fast first pass that still needs a human read, and they are a legitimately useful free tool.

Finviz: the free market-wide pattern screen

Finviz attacks the problem from the screener side. Its free stock screener includes pattern filters: head and shoulders and its inverse, rising and falling wedges, ascending and descending triangles, channels, double tops, double bottoms, and multiple-top and bottom variants. Pick "Head and Shoulders" and the screener returns every US stock whose recent price history matches the rule set, in seconds, without an account.

Each pattern is rule-defined and documented. Finviz's head and shoulders, for instance, requires a prior uptrend, three distinct highs with the head highest and the shoulders near equal, and a break of the horizontal support under the pattern. Knowing the definition matters, because a rule-based screen returns everything that fits the geometry, including charts a human would reject on sight. Expect to click through the candidates and throw most of them out; the screen's value is shrinking eight thousand charts to thirty, and it does that for free.

The paid tier, Finviz Elite, adds the visual half: patterns and trendlines drawn automatically on the charts, plus real-time data (the free tier's quotes are delayed). If you only need the discovery step, free Finviz plus your own charting app is one of the strongest zero-cost pattern workflows available, and pairing it with a proper read of support and resistance covers most of what the paid scanners automate.

Trade Ideas: pattern scanning at day-trader speed

Trade Ideas is a live scanning engine aimed at intraday traders, and patterns are one input among many. Head and shoulders, cup and handle, pennants, wedges, and triangles are available as scan conditions that combine with any indicator or fundamental filter, so "cup and handle forming, above the 200-day, with relative volume over 2" fits in a single scan. Its AI layer, Holly, runs dozens of curated strategies simultaneously each day and surfaces entry and exit signals without configuration.

The honest framing is that Trade Ideas is priced and designed for people treating trading as a job. The subscription costs more per month than most swing traders would save from it, the interface assumes screen time, and the edge it sells (speed to a forming setup during market hours) matters most on intraday timeframes. If you check charts after work, Finviz covers the discovery step at a fraction of the cost. If you scalp momentum every morning, this is the tool the others are imitating.

Tickeron: pattern calls with a probability attached

Tickeron does one thing the rest of this list does not: it grades its own calls. Its AI scans thousands of stocks and ETFs each minute for pattern signals and attaches a success probability and a confidence rating to each one, so every detection carries the model's estimate of how often that setup has resolved as expected.

That number is the draw and the caveat in one. A probability makes signals comparable and forces some discipline about which flags deserve attention, and it is still a model estimate built from historical fits, at risk from the same survivorship problems as any backtest. A trader on r/technicalanalysis described running the math on visual patterns across a few hundred symbols and watching the edge mostly evaporate once the failed instances were counted. Tickeron's ratings are an attempt to price that failure rate into each signal, which is more honest than raw detection; just resist reading 68% as a promise. Pricing is tiered by feature, and the tiers add up, so match the subscription to the signals you will actually trade.

Patternz: the free encyclopedia option

Patternz is free desktop software from Thomas Bulkowski, the trader whose reference books catalogued chart pattern statistics for most of the patterns the paid apps detect. It recognizes both chart patterns and candlestick formations across the price data you load into it, and it costs nothing.

The trade-offs are exactly what free desktop software implies: an interface that looks its age, a manual workflow for getting data in, and no cloud, mobile app, or alerts. What you get in exchange is detection logic from the person who wrote the pattern literature, with his measured statistics a bookshelf away. For a methodical trader who wants pattern recognition without a subscription and does not mind a clunky setup step, Patternz is the best pure value on this page. For anyone who wants a polished app, it will feel like a spreadsheet from 2009, because roughly speaking it is one.

One adjacent mention: Autochartist, which forex and CFD traders will run into, is distributed as a plug-in through brokers rather than as an app you buy directly. If your broker bundles it, pattern alerts are already in your platform; if yours does not, you cannot meaningfully shop for it.

Where Quant AI fits

Every app above assumes the chart lives inside its own platform. Quant AI works on the chart you actually have: screenshot any stock, crypto, or forex chart from any app, and it marks the pattern, the trend, and the key levels in seconds, with no account setup and no watchlist. It detects chart patterns from a screenshot the way the platforms above detect them in their own data.

That makes it the tool for a different moment than a scanner. A scanner answers "what is forming across the market today?" before you have a candidate. Quant AI answers "what is this?" after you have one: the chart a friend sent, the ticker from a feed, the position already open in a broker app with no pattern tools. It also covers the checking step this article keeps returning to, reading the structure around a flagged pattern before trusting the flag.

What it is not: Quant AI does not scan watchlists, run backtests, or place orders. If you need market-wide discovery, pair it with Finviz or TrendSpider; if you need execution, your broker keeps that job.

Why scanner alerts land late

Every detection tool on this page shares a constraint that explains most user disappointment: a pattern is only mechanically confirmable after the structure that defines it is finished. The apps are not slow; the geometry is.

Walk through a double bottom. A stock slides from $48 to $40.20, bounces to $43.60, and rolls over again. At this point no honest algorithm can call it a double bottom; a second low does not exist yet. Price bases at $40.35, which a scanner can start flagging as a potential pattern in progress (TradingView's and TrendSpider's engines both mark forming patterns). Confirmation, by the textbook and by most detection rules, only arrives when price breaks the neckline at $43.60. That break is the alert. By the time it fires and you open the chart, price is often already at $44 and change, and the measured move to roughly $47 (neckline plus the pattern's depth) has spent part of itself.

Line chart of a double bottom over fourteen sessions. Price falls from 48 to a first low at 40.20, rebounds to a neckline at 43.60, declines again to a second low at 40.35, then rallies through the neckline and continues to 45.80. A marker labels the neckline break at 43.60 as the point where a scanner alert fires, several bars and several percent after the second low where the pattern actually began resolving. A dashed horizontal line marks the neckline at 43.60 and a green line marks the measured target near 47.

This is why "in progress" detection matters more than completed-pattern detection when you compare apps. TradingView drawing a forming head and shoulders, or TrendSpider flagging a triangle that price is still respecting, gives you the planning window: where the breakout level is, where the stop belongs, what invalidates the idea. An alert on the completed pattern gives you a decision to chase or skip. Both are useful; only one of them is early.

The checklist no scanner runs

Detection tells you the shape matched. The traders who actually make pattern trading work keep pointing at everything the shape leaves out. One comment on r/technicalanalysis compressed it into a sentence worth keeping:

"A pattern name is not a setup by itself. The missing pieces are location, context, volatility, volume, and invalidation."

Run a flagged pattern through those five before acting on it.

Location. A triangle compressing under resistance after a strong uptrend and an identical triangle drifting in the middle of six months of chop are the same shape with different odds. Where the pattern sits relative to real levels decides most of its meaning, which is why marking support and resistance first is not optional homework.

Context. Patterns inherit the trend they form in. The same trader community that mocks $50 candlestick cheat-sheet PDFs keeps making an unglamorous point: beginners match a textbook shape on a secondary trend and trade it against the primary one. A bull flag inside a downtrend is usually just a pause in selling.

Volatility. A pattern spanning a 3% range on a stock that moves 3% a day is noise wearing a costume. Scanners match geometry at any scale; your risk budget does not.

Volume. The most repeated confirmation rule in every pattern guide, and the one no detection flag on this page enforces. A neckline break on double average volume and one on a quiet summer Friday get the same alert.

Invalidation. The point where the idea is wrong: below the second low of a double bottom, above the right shoulder of a head and shoulders. If you cannot state the invalidation price, you have a picture instead of a trade. Our guides on the head and shoulders and the cup and handle both walk through this with worked numbers.

The blind-test threads that circulate on trading forums (hide the right side of the chart, predict the continuation) keep producing the same confession: high confidence, poor accuracy, reversals called too early, patterns seen where none existed. Software does not fix that bias. It industrializes the pattern-finding half and leaves the judgment half entirely to you, and the judgment half is where the money is decided.

Fast tape breaks slow signals

One more failure mode worth naming, because June 2026 just demonstrated it. On June 5 the Nasdaq-100 fell 5%, its worst session since the previous October, and the weeks after were dominated by a handful of concentrated, high-beta movers. Pattern and momentum scanners had a violent month in both directions: the selloff completed breakdown patterns everywhere at once, and then the snap-backs invalidated fresh continuation signals within days.

The lesson generalizes. Pattern detection assumes the structure resolves at roughly the tempo it formed. In a fast tape, a signal that was valid at the scan is stale by the open, and a stop based on the pattern's geometry can be gapped through before it matters. When the whole market is moving on one theme, pattern flags multiply exactly when their reliability drops, because everything is correlated to the index and none of the individual structures mean much. Scanners are at their best in an orderly market and at their noisiest in a dramatic one, which is the opposite of how it feels to use them.

Frequently asked questions

What is the best app for stock patterns overall?

For most retail traders the practical answer is a pair: a free market-wide screen (Finviz, or Webull's screener) to find candidates, plus a chart-level tool to read each candidate properly (TradingView if you chart there, Quant AI if the chart is a screenshot). The single-app answer is TrendSpider if the budget clears, because it covers discovery, drawing, and backtesting together, and thinkorswim if it does not.

What is the best free app for detecting chart patterns?

Depends on the job. Thinkorswim has the deepest free chart-level detection, including a custom pattern editor. Finviz has the best free market-wide pattern screen. Webull is the best free phone-first option. Patternz detects the most patterns for literally zero dollars if you tolerate its interface. All four are genuinely free, with no trial clock attached.

Is there a scanner that finds stocks showing a specific candlestick?

Yes. Webull's screener filters the market by candlestick pattern directly. Thinkorswim goes further: its Candlestick Pattern Editor lets you define your own bar sequence and then find it. Finviz's technical filters cover some candle-adjacent conditions too. This question gets asked on trading forums as if it were exotic; it has been a free feature for a while.

What is the best chart pattern screener for cup and handle or head and shoulders?

Finviz screens for head and shoulders (and its inverse) free, US stocks only. TrendSpider scans for cup and handles, head and shoulders, and most classic patterns across US equities and adds backtesting. For markets outside the US (this question comes up constantly for NSE stocks in India, for example), coverage thins out fast: TradingView's auto patterns work on whatever chart you open, including international symbols, which makes it the most market-agnostic option, and screenshot-based reading works on any market because it never touches a data feed.

Do pattern scanners actually work?

They work at the job of finding shapes, and they are honest about nothing else. The recurring finding when traders test patterns systematically is that raw geometric matches carry little edge once failed instances are counted; the results improve when location, trend, volume, and a defined invalidation are layered on top. A scanner compresses hours of chart-flipping into seconds, which is real value. It does not convert a 50/50 shape into a setup. The filter you apply after the scan is the actual strategy.

Can AI read a chart screenshot and tell me the pattern?

Yes. That is Quant AI's whole design: screenshot any chart from any platform and it returns the pattern, trend direction, and key levels in seconds. It is the only approach on this page that works when the chart is not inside your own data feed, which in practice is most charts a trader encounters in a day: broker apps, group chats, and social feeds. Treat the read the way you would treat any detection: it is the first step of the checklist above.

Why does my scanner keep flagging patterns that already broke out?

Because confirmation is retrospective by definition. Most detection rules require the completing event (the neckline break, the trendline breach) before a pattern graduates from "forming" to "confirmed," so completed-pattern alerts systematically arrive after the first leg of the move. Two fixes: use tools that flag patterns in progress (TradingView's built-ins and TrendSpider both do), and treat each alert as a prompt to plan the retest or the next setup on that symbol; chasing the bar that triggered it is how the late entries happen.

The bottom line

TradingView for patterns drawn where you already chart, now at Premium prices. TrendSpider for the full automated stack if you trade enough to justify it. Thinkorswim and Webull prove detection itself is now free. Finviz for finding candidates across the whole market without paying, Trade Ideas for finding them live at day-trader speed, Tickeron for signals with a stated failure rate, Patternz for the no-subscription purist. Every one of them stops at the same line: the flag tells you a shape exists, and says nothing about the level it formed at, the volume behind it, or the price that proves it wrong. That read takes seconds when the chart is in front of you. Screenshot it into Quant AI and it marks the pattern, the trend, and the levels, so you can spend your attention on the only question the scanners leave open: whether this one is worth trading.
