AlpharvestProBest Free Stock Screener: What to Look For (and What 'Free' Really Means)最佳免費選股工具：評選要點與「免費」的真正涵義
What Does "Free" Actually Mean in a Stock Screener?
Search "free stock screener" and you will find tools that use the word "free" to mean very different things. It helps to separate three models before you choose:
- Truly free — core screening and results are usable with no payment, sometimes with a free account. Limits are on convenience (saved screens, export), not on whether you can screen at all.
- Freemium — a real free tier exists, but the most useful filters, markets or data history sit behind a paid plan.
- Free trial — full access for a few days, then a paywall. Useful to evaluate, not to rely on long-term.
None of these is "wrong" — but knowing which one you are using prevents the frustration of building a routine around a tool that asks for a card the moment you find something. The best free stock screener for you is the one whose free capabilities actually cover the way you screen.
選股工具中的「免費」究竟是什麼意思？
搜尋「免費選股工具」，你會找到對「免費」二字意涵截然不同的各種工具。選擇之前，先區分三種模式會很有幫助：
- 真正免費 — 無需付費即可使用核心篩選功能並查看結果，有時需要免費帳號。限制在於便利性（已儲存篩選條件、匯出功能），而非是否能篩選本身。
- 免費增值 — 確實存在免費方案，但最實用的篩選條件、市場或歷史資料藏在付費方案背後。
- 免費試用 — 幾天內享有完整存取，之後出現付費牆。適合評估用，不適合長期依賴。
這三種模式都沒有「錯」——但了解你正在使用哪一種，能避免你圍繞一個工具建立好日常流程後，才在發現好標的的那一刻被要求輸入信用卡號的挫折感。對你而言最好的免費選股工具，是其免費功能實際上能涵蓋你選股方式的那一個。
What to Look For in a (Free) Stock Screener
Price aside, a screener is only as good as what it lets you filter on and trust. A short checklist:
- The metrics that matter. Can it rank by relative strength, confirm a trend (moving-average structure), and flag base patterns — or only basic fundamentals and raw price change? Momentum investing lives or dies on relative strength.
- Universe coverage. One market or several? If you follow leadership across the US and Asia, a single-market tool means juggling several screeners.
- Data freshness. Is the screen rebuilt every trading day, and is the data date clearly shown? A stale screen is worse than none.
- Transparency of method. Does it explain *how* a score is calculated, or is it a black box? You should be able to trace why a name appears.
- No signal pressure. A good screener produces *candidates for research* — not "buy now" alerts that nudge you to trade.
評選（免費）選股工具的要點
撇除價格不論，一個選股工具的好壞，取決於它讓你篩選什麼、以及你有多信任那些資料。簡短的確認清單：
- 重要的指標。 它能依相對強度（RS）排名、確認趨勢（均線結構），並標記底部型態嗎——還是只有基本面數字與原始漲跌幅？動能投資的成敗取決於相對強度。
- 選股範疇的廣度。 單一市場還是多個市場？如果你追蹤美股與亞股的領漲格局，單一市場工具意味著要在多個選股平台之間切換。
- 資料新鮮度。 篩選結果是否每個交易日重新建立，且資料日期是否清楚標示？過時的篩選結果比沒有更糟。
- 方法論透明度。 它有解釋評分是如何計算的，還是一個黑箱？你應該能追溯為何某支股票出現在清單上。
- 沒有操作壓力。 好的選股工具產出的是*研究候選標的*——而非催促你交易的「立即買進」提示。
Free vs. Paid: What You Actually Get at Each Tier
In most momentum-screening tools the split looks roughly like this:
| Capability | Typical free tier | Typical paid tier |
|---|---|---|
| Daily ranked candidates | ✅ usually | ✅ |
| Relative strength / trend filters | ✅ often | ✅ deeper |
| Market breadth & heatmaps | ✅ sometimes | ✅ |
| Full historical archives | ⚠️ limited | ✅ |
| Multiple saved screens / export | ⚠️ limited | ✅ |
| Every market & every report type | ⚠️ partial | ✅ |
The practical takeaway: a strong free tier is usually enough to learn the method and find candidates. You upgrade when you want depth — full archives, every market, and the heavier report types — not to unlock basic screening.
免費與付費：各方案實際提供的功能
在多數動能選股工具中，功能區分大致如下：
| 功能 | 典型免費方案 | 典型付費方案 |
|---|---|---|
| 每日排名候選標的 | ✅ 通常有 | ✅ |
| 相對強度與趨勢篩選 | ✅ 多數情況有 | ✅ 更深入 |
| 市場寬度與熱力圖 | ✅ 有時有 | ✅ |
| 完整歷史資料封存 | ⚠️ 有限 | ✅ |
| 多組已儲存篩選條件 / 匯出 | ⚠️ 有限 | ✅ |
| 所有市場與所有報告類型 | ⚠️ 部分 | ✅ |
實際結論：強大的免費方案通常足以學習方法論並尋找候選標的。只有當你想要更深入的功能時才需要升級——完整封存、所有市場，以及更進階的報告類型——而非只是解鎖基本篩選功能。
The Metrics That Matter More Than the Price Tag
A free screener that ranks by the right things beats an expensive one that ranks by the wrong things. The three layers that separate leaders from noise are the same regardless of price:
| Layer | What it tells you | Deep-dive guide |
|---|---|---|
| **RS Rating** | Which stocks are actually outperforming the market (keep RS ≥ 70) | Relative strength |
| **Stage 2 / Trend Template** | Whether a real uptrend is in place | Minervini stage analysis |
| **VCP base** | Whether a stock is tightening toward a breakout | VCP pattern detection |
If a free tool lets you screen on these, you can run a disciplined momentum process without paying for anything. See the full momentum-screening pillar guide →
比價格標籤更重要的指標
能依正確指標排名的免費工具，勝過依錯誤指標排名的昂貴工具。無論價格如何，區分主流強勢股與雜訊的三個層次始終相同：
| 篩選層次 | 代表意義 | 深度指南 |
|---|---|---|
| **RS 評級** | 哪些股票真正跑贏市場（保留 RS ≥ 70） | 相對強度 |
| **第二階段／趨勢範本** | 真實上升趨勢是否成立 | 明納維尼階段分析 |
| **VCP 底部** | 股票是否正在收縮蓄勢突破 | VCP 型態偵測 |
如果免費工具能讓你依這些條件篩選，你就能執行嚴謹的動能選股流程，無需付費。查看動能選股總指南 →
How AlpharvestPro's Free Tier Works
AlpharvestPro is built education-first, so the core is free to use every trading day:
- Open the screener — no payment needed to start; a free tier covers all four markets (US, Japan, Taiwan, Hong Kong).
- Pick a market and universe — focused index (S&P 500, JPX-400, TW200, HSLMI) or the broader market.
- Screen by the metrics that matter — relative strength, Stage 2 trend, and VCP/OWL base patterns, the same methodology across every market.
- Read the free daily candidates and breadth — the daily candidate lists and the momentum breadth dashboard are free to view, with the data date shown.
- Upgrade only if you want depth — full archives, every report type and the heavier tools sit in the paid tier; basic screening never does.
The output is always a list of candidates for research, never a buy list. Try the free screener →

Common Mistakes When Choosing a Free Screener
- Choosing on price alone — a free tool that only ranks raw price change will mislead you. Prioritise *what* it filters on over what it costs.
- Mistaking a trial for a free tier — confirm whether access continues after a few days, or you will rebuild your routine twice.
- Trusting stale data — if the screen does not show a clear, recent data date, do not act on it.
- Chasing "alerts" instead of candidates — a screener should hand you names to research, not pressure you to trade.
- Using one single-market tool for global leadership — if you follow US and Asian leaders, pick a screener that covers them in one place.
選擇免費選股工具時的常見失誤
- 只看價格選工具 — 只依原始漲跌幅排名的免費工具會誤導你。優先考量它*依什麼*篩選，而非它的價格。
- 把試用期誤認為免費方案 — 確認幾天後是否仍可繼續使用，否則你將需要重新建立兩次流程。
- 相信過時的資料 — 如果篩選結果未顯示清楚且近期的資料日期，請勿據此行動。
- 追逐「提示」而非候選標的 — 選股工具應該提供你需要研究的標的名稱，而非催促你交易。
- 用單一市場工具追蹤全球領漲格局 — 如果你同時追蹤美股與亞股主流強勢股，請選擇能在同一平台涵蓋所有市場的工具。

FAQ
Is there a genuinely free stock screener?
Yes. AlpharvestPro's interactive screener has a free tier covering all four markets, and the daily candidate lists and momentum breadth dashboard are free to view. You can run a disciplined momentum screen without paying.
What is the best free stock screener for momentum investing?
The best one for you is whichever lets you rank by relative strength, confirm a Stage 2 trend, and spot VCP bases — for free, across the markets you actually follow. Price matters far less than whether it filters on the metrics that identify leaders.
What is the catch with free screeners?
Usually the free tier limits depth — full historical archives, multiple saved screens, exports, or some report types — rather than basic screening itself. Always check whether you have a true free tier or just a time-limited trial.
Do I need to pay to screen US, Japan, Taiwan and Hong Kong stocks?
No. AlpharvestPro's free tier covers all four markets with the same methodology. You only upgrade for depth — full archives and the heavier report types — not to screen.
Is a free screener a buy list?
No. Any good screener, free or paid, produces candidates for research. Your own chart analysis, risk management and entry timing always come after. This content is educational and not investment advice.
常見問題
真的有免費的選股工具嗎？
有。AlpharvestPro 的互動式選股工具設有涵蓋四個市場的免費方案，每日候選清單與動能寬度儀表板均可免費查看。你無需付費就能執行嚴謹的動能選股流程。
動能投資最佳的免費選股工具是哪一個？
對你而言最好的，是能依相對強度（RS）排名、確認第二階段趨勢、並發現 VCP 底部——免費地、針對你實際追蹤的市場——的工具。價格的重要性，遠不及它是否能依識別主流強勢股的指標進行篩選。
免費選股工具有什麼陷阱？
通常免費方案限制的是深度——完整歷史封存、多組已儲存篩選條件、匯出，或部分報告類型——而非基本篩選功能本身。務必確認你擁有的是真正的免費方案，還是有時間限制的試用期。
我需要付費才能篩選美股、日股、台股與港股嗎？
不需要。AlpharvestPro 的免費方案以相同方法論涵蓋四個市場。你只有在需要深度功能時才需要升級——完整封存與更進階的報告類型——而非為了篩選本身。
免費選股工具的結果是買進清單嗎？
不是。任何優質的選股工具，無論免費或付費，產出的都是研究候選標的。你自己的圖表分析、風險管控與進場時機，始終是在篩選之後才進行的。本內容僅供教育目的，不構成投資建議。
