Is Trend Screener free? Do I need an account?
Yes — it's entirely free, with no sign-up or login required. The U.S. and Korean screeners, Industry Rankings, and Market Environment pages are all available at no cost.
Is this real-time data?
No. Trend Screener does not provide real-time or intraday quotes. Every figure is computed once a day from confirmed daily closing bars after the market closes. It should not be used to check intraday prices.
How often is the stock list updated?
It is recomputed and refreshed automatically after each trading day's close — from the confirmed daily bars once the U.S. close (16:00 ET) and the Korean close (15:30 KST) are final.
What does "8/8" in the table mean?
It means the stock passed all 8 conditions of Mark Minervini's Trend Template. Only when all eight are met do we treat it as a strong stock in a Stage 2 uptrend. Each condition is laid out on the Methodology page.
What does RS 99 mean?
An RS Rating of 99 means the stock is among the top 1% by momentum across the whole market right now. RS is a percentile rank versus the market (1–99), not an absolute return.
How do I use the "RS" and "Industry" filters together?
Raise the RS floor to 90 (or 80/70/60) and only top-momentum names remain; then check the top-ranked groups in the industry filter — as many as you like at once — and only those industries remain. Stacked, the two give you strong stocks inside strong industries, applying the principle that a trend is most reliable when a strong stock sits inside a strong industry.
Why is the "Volume" filter separate?
Volume (the 50-day average) is an optional filter kept separate from the pass conditions. The default screen shows every strong-trending stock even if thinly traded, and you can set a floor (100K / 500K / 1M / 3M shares in the U.S., 50K / 100K / 300K / 1M in Korea) when you want only actively traded names.
What is the ADR% filter, and why the 3-5% range?
ADR% (Average Daily Range) is how much higher the high was than the low on an average day over the last 20 trading sessions - in short, how far a stock travels in a day. It is shown per stock in the ADR column, and the filter lets you set a floor of 3% / 3.5% / 4% / 4.5% / 5%. That range is the conventional one in trend following: around 3% is the starting line, because quieter names can be in a perfectly valid uptrend and still take months to produce a move worth trading. Higher is not automatically better, though - a more volatile stock needs a wider stop, so holding risk constant means taking a smaller position. Use the 0.5% steps to find the range that matches your own stop distance and holding period. Like the volume filter, it has no effect on the 8-condition pass determination.
How is the industry ranking's "Industry Score" calculated?
The Industry Rankings page ranks every industry on one number: the cap-weighted composite return of its members — 0.10×1W + 0.30×1M + 0.40×3M + 0.20×6M (the same windows and weights as a stock's RS, √cap weighted with a 15% single-name cap). That return, converted to a percentile within the day's cross-industry distribution, is the 0–100 Industry Score; the table lines up this week's, 3-week-old and 6-week-old ranks so rotation reads in one row. The four cards on top are sector ranks #1–#4, applying the same formula to the SPDR sector ETFs in the U.S. and to cap-weighted member baskets in Korea. The five-pillar sum used through July 2026 (performance, leadership, breakouts, breadth, setup) correlated 0.90 with performance alone while letting density ratios distort thin groups, so it was dropped from the score — the metrics themselves remain on the detail panel as evidence. The full criteria are on the Methodology page.
Does the screener order industries the same way as the Industry Rankings page?
Yes — same basis. The ordering of the screener's industry filter list (the rank number before each item) follows the same Industry Score (0–100) ranking as the Industry Rankings page, so you can tick the top groups you saw there from the top down. Industry relative strength (industry RS) — a 1–99 measure of a group's relative strength alone — remains a separate auxiliary metric, used only as a fallback when ranking data is unavailable.
What is the score (TSS) on the "Market Environment" page?
TSS (Trend Strength Score) summarizes, in a single 0–100 number, whether the current tape favors trend-following and breakout trading. It sums three pillars — Breadth · Institutional Flow · Index Trend — reading 77+ as a strong trend and below 23 as risk-off (all-neutral inputs score 50). It updates after each market close on the confirmed daily bar.
Are the up/down colors reversed between the U.S. and Korean screens?
Following Korean investor convention, this site uses red for up and blue for down throughout. That's the opposite of U.S. charts (green for up, red for down), so keep it in mind when switching between the two markets.
A newly listed stock isn't showing up.
A stock with fewer than 250 sessions (about a year) since listing has no comparable base, so it stays out of the RS population; with no RS rating it cannot meet the 'RS 70 or above' condition and never reaches the pass list.
Why are some stocks missing?
ETFs and preferred shares are excluded, and in the U.S. anything closing under $1 is dropped. Korea excludes nothing by price or market cap — instead, names under roughly ₩10 billion carry no weight in the cap-weighted industry and sector returns, which is what keeps micro-caps from distorting the ranking.
Are the selected stocks buy recommendations?
No. Trend Screener's results are reference material produced by mechanically applying technical rules — not investment advice or stock recommendations. The final decision and responsibility rest entirely with you.
Where does the data come from?
We collect and process confirmed daily bars (OHLCV) from external market-data providers after the close. The full set of formulas and selection criteria is published on the Methodology page.
Does it work on mobile?
Yes. Every page is responsive for mobile screens, and you can scroll the tables horizontally to see all columns.
