What changed, and when.

Methodology & corrections

Changes to the measurement, and things we got wrong

Every entry below is dated to the day the change merged, and every date is verifiable against the public repository history. Corrections stay on the page permanently, including the ones that are embarrassing. If a factor’s implementation changes, its methodology page changes with it and the change is logged here.

1. 2026-07-18scope#360

   Stopped collecting investing experience and portfolio size

   Onboarding previously asked for investing experience level and portfolio size. Both questions were removed and are no longer collected anywhere on the site. Tapeline does not ask for capital, holdings, risk tolerance, experience or investment goals, which is what keeps its output general information rather than something tailored to an individual.

2. 2026-07-18scope#345, #348, #349

   Free tier restated to match what the product actually enforces

   Pricing and comparison surfaces were corrected to describe the free tier as it is enforced in the backend: 12 ticker look-ups per day, a 5-slot watchlist, the top 10 live scanner rows, a top-3 squeeze preview, 2 web-push alert rules, and the full public scorecard. Several pages had been describing older, tighter limits that no longer applied. The enforcement itself was widened the previous day, on 2026-07-17.

3. 2026-07-12disclosure#342

   Exact factor weights, the scoring equation and indicator lists removed from the site

   The public site previously published the numeric weight of each factor, the composite equation, and per-factor indicator and parameter lists. Those were removed. What is still published: the six factor names, the relative ordering of the weights, each factor's contribution on every ticker, and the full public scorecard. The reason is competitive, not evasive — the numeric recipe was the part a competitor could copy directly. The scoring behaviour itself did not change on this date; only what the site discloses about it.

4. 2026-07-11correction#337, #359

   Prescriptive advice and performance claims removed from live pages

   A review found copy on live pages that told readers what to do with a score, and copy that implied the product produces returns. Both were removed. Signal labels describe the state of the factor data; they do not prescribe an action. A follow-up on 2026-07-18 added an automated check that fails the build if that language reappears.

5. 2026-07-09methodology#329, #330

   Liquidity floor applied to the ranked scanner and the scorecard

   High-scoring names that barely trade could top the ranked list and be frozen onto the scorecard. A liquidity floor now filters them out of both. This changed which names QUALIFY going forward only — no historical scorecard day was altered, and every past entry stands as recorded. Names with no volume reading are left in, and the floor can be switched off on the scanner to browse the full scored universe.

6. 2026-05-17correctionv0.1.12

   Smart Money was described as 13F holdings; it reads SEC Form 4

   Marketing copy across pricing, comparison and per-ticker pages described the Smart Money factor as using 'elite 13F holdings'. That was wrong. The factor reads corporate-insider transactions disclosed on SEC Form 4, which is what the underlying code had been doing all along. The copy was corrected to match the implementation rather than the other way round.

What each factor measures and where it falls short is on the methodology pages. What the product as a whole is weak at is on limitations. Found something wrong? Email support@tapeline.io and the correction gets logged here with a date.

Releases

What we shipped, when

1. Rankings + scorecard now filter out untradeable names

   improvement

   v0.1.15 · 2026-07-10

   • ·The scanner and the public scorecard now apply a liquidity floor. High-scoring names that barely trade — a bond or single-strategy ETF changing hands a few hundred dollars a day — no longer top the ranked list or get frozen onto the scorecard. A score you can't realistically act on isn't useful, so the tradeable names come first now.
   • ·Methodology note, in keeping with our published practice: this only changes which names qualify going forward. No past scorecard day is touched — every historical pick, winner or loser, stays exactly as it was recorded. We don't rewrite the record.
   • ·Names with no volume reading are left in, so the filter only ever removes rows that are genuinely untradeable. On the scanner you can still turn the liquidity floor off to browse the entire scored universe.

2. Founding pricing: Pro $9.99/mo, Premium $19.99/mo · 30-day money back

   improvement

   v0.1.14 · 2026-07-03

   • ·New founding pricing across every plan: Pro is $9.99/mo or $99/yr ($8.25/mo effective), Premium is $19.99/mo or $199/yr ($16.58/mo effective). Tapeline is new and the price now says so — subscribers keep their rate for as long as the subscription stays active. No countdowns, no fake scarcity.
   • ·Money-back guarantee extended from 7 days to 30 days on every paid plan — email support@tapeline.io within your first 30 days for a full refund, no forms.
   • ·Feature gating unchanged: same tiers, same limits, same 14-day no-card Premium trial.

3. Public /data-sources page; squeeze list back to populating

   shipped

   v0.1.13 · 2026-05-17

   • ·New /data-sources page lists every feed that powers a Tapeline score — what it's used for, where it shows up in the product, how often it refreshes, and whether it's public-domain or licensed. Six feeds covered end-to-end: prices, fundamentals, SEC filings, macro, news, and the composite scoring workbook. Linked from the footer's transparency strip.
   • ·Squeeze list on /app/squeeze now populates again. An upstream schema change meant the page was rendering an empty table for ~12 hours; the parser now reads the new format and the spike scores are back live.
   • ·Licensing posture written into the data-sources page as a Public domain vs Licensed badge per feed — same standard as the public scorecard and signal-methodology disclosures.

4. Honest about what powers Premium — insider Form 4, not elite 13F

   improvement

   v0.1.12 · 2026-05-17

   • ·Premium feature line updated across pricing, comparison pages, and per-ticker share pages: 'Elite 13F holdings' replaced with 'Recent insider buys (SEC Form 4)'. What's on the /app/holdings page hasn't changed — same SEC Form 4 transactions that have been live for weeks — the marketing copy just now matches what's actually delivered.
   • ·Smart Money factor explanation updated everywhere: Form 4 insider transactions + Congressional disclosures. No mention of 13F.
   • ·Open API roadmap, comparison tables, and the LLM-readable site facts all reconciled. No promise the product can't deliver.

5. Live signal-system universe, iOS-feel design, light + dark mode

   shipped

   v0.1.11 · 2026-05-17

   • ·Tapeline now reads the full ranked ticker universe live from its source of truth — refreshed every 5 minutes. The scanner went from 112 mock tickers to 7,162 tickers tracked, 4,399 of them actively scored, including names like HYLN that were missing before.
   • ·Light, Dark, and System appearance modes — toggle in your account menu (top-right). System mode follows your Mac/Windows theme automatically as you change it.
   • ·Heatmap rebuilt around 14 clean GICS sectors (Information Technology, Health Care, Financials, Industrials, Consumer Discretionary, Consumer Staples, Communication Services, Energy, Materials, Utilities, Real Estate, Commodities, Funds & ETFs, Uncategorized). Was 51 fragmented labels; the dropdown filter now actually matches what's on the page.
   • ·Search box on both the scanner and the heatmap — type any ticker substring, results filter live.
   • ·Material event filings from SEC EDGAR now appear in the breaking-news bar ~5-30 minutes before they're re-reported by the news wires. 8-Ks, item codes, the lot. Free, regulatory-quality, no marketing fluff.
   • ·Recent insider buys page (Premium) populates correctly now — was showing empty regardless of the data behind it.
   • ·Per-ticker page shows the proper 'No fundamentals coverage for ETFs and funds' message instead of six empty cards when a ticker is an ETF.
   • ·New design language across the dashboard: translucent surfaces, frosted-glass cards, system-font stack, pill buttons. No more boxed-template borders.
   • ·Fluid type — the whole UI compresses cleanly as you narrow the window. Cell padding tightens on the scanner table so the numeric grid stays the focus on laptops and small screens.
   • ·News bar now shows 3 headlines at once (was 1 rotating) and pulls 20 per refresh (was 8) so the feed actually feels active.
   • ·Authenticated actions like Add to Watchlist and Notify on News no longer return errors — a cross-origin cookie issue that affected most dashboard buttons.
   • ·Four Pro/Premium endpoints (Congress, Heatmap, Squeeze, Regime) that were accidentally accessible without authentication despite the UI gating them — now properly gated end-to-end.
   • ·Top-right search shortcut chip now reads 'Ctrl K' on Windows and Linux. Was the Mac Command symbol everywhere.
   • ·New /app/account hub — your username menu links here for a single home for billing, watchlist, alerts, email preferences, and the new appearance toggle.

6. New tagline, clearer privacy policy, payment-failed email

   improvement

   v0.1.10 · 2026-05-15

   • ·New product tagline across the site: Read the tape.
   • ·Privacy policy rewritten to match what Tapeline actually does today — no stale references to tools or sub-processors no longer in use, and a clear note that request IP addresses live in memory only, not in any persistent log.
   • ·New email when a renewal charge fails — a calm note with a one-click link to update your card, the moment the failure happens. Stripe's automatic retry behaviour is unchanged; the difference is you find out immediately rather than when access drops.

7. Referrals, signup hardening, 50 per-ticker SEO pages

   shipped

   v0.1.9 · 2026-05-14

   • ·Referral mechanic live. Share your code from /app/referrals — both you and the friend you refer get one free month of Premium, credited at the next paid checkout.
   • ·Signup form is more forgiving with intermittent Turnstile loads, so fewer real users get bounced. Signing out now reliably clears the session across every Tapeline subdomain.
   • ·50 new per-ticker landing pages at /blog/ticker/{SYMBOL} — AAPL, NVDA, MSFT and 47 others. Each renders the live Tapeline composite, the 6-factor breakdown, and a structured FAQ so the page is useful in search results.
   • ·Referrals page now shows 0 unused credits cleanly if you've never referred anyone, instead of a momentary blank.

8. Sharper Pro vs Premium presentation, faster app pages

   improvement

   v0.1.8 · 2026-05-04

   • ·Premium plan card now leads with what it adds on top of Pro (Congress feed, elite 13F, unlimited Telegram + email, public API, larger watchlist) instead of duplicating the Pro list.
   • ·Loading states across the app now show shimmer placeholders in the shape of the eventual content — the product feels noticeably snappier on first visit.
   • ·Per-ticker public share pages (/t/AAPL, /t/NVDA etc.) render the live score and 6-factor breakdown without needing a sign-in. Share-on-X button included.
   • ·Public scorecard, status page, and blog all reachable from every page footer.

9. Real earnings + IPO calendars; live macro indicators

   shipped

   v0.1.7 · 2026-05-03

   • ·Earnings calendar now reflects 1,500 upcoming reports across the next two weeks, not a sample.
   • ·IPO calendar shows actual upcoming listings (Rare Earths Americas, HawkEye 360, etc.) sorted by expected date.
   • ·Macro tile (DXY, 10-year, VIX) on the regime page now pulls live macro indicators instead of static defaults.
   • ·Per-ticker confidence pill on the scanner — mega-caps with full coverage land 90+; less-followed names sit lower so you can deprioritise signals built on thin data.

10. Browser push alerts + end-of-day digest

    shipped

    v0.1.6 · 2026-05-02

    • ·Browser push notifications — lock-screen alerts on desktop and Android, one click to enable. Free at any volume on Pro+.
    • ·End-of-day watchlist email digest fires every weekday after market close for every Pro+ user with watchlist items.
    • ·Continue-with-Google sign-in option now appears on the signin and signup pages.

11. Elite 13F holdings, harder Free tier, three competitor comparisons

    shipped

    v0.1.4 · 2026-04-27

    • ·Elite-fund 13F holdings live for Premium: latest positions from Buffett, Burry, Tepper, Ackman, Druckenmiller, Laffont, Coleman, Singer.
    • ·Free tier reworked at the time so the trial-end transition was meaningful. (Since superseded: Free is now live scores on the top-10 scanner with 5 look-ups/day, free forever — see /pricing.)
    • ·Plain-English Why on every scanner row rewritten with sector-aware language across ~100 phrase variants.
    • ·Side-by-side comparison pages live for Finviz, Zacks, and WallStreetZen.

12. Telegram alerts (Premium), commodity ETF universe, three-tier pricing

    shipped

    v0.1.3 · 2026-04-26

    • ·Telegram alert channel for Premium subscribers — paste a chat ID on the billing page, send a test, get hourly market-regime + watchlist digests plus per-rule alerts.
    • ·32 commodity ETFs added to the scanner universe (gold, silver, oil, gas, agriculture, copper, uranium, miners) with a dedicated Commodities sector filter.
    • ·Pricing simplified to three tiers: Free, Pro $29/mo, Premium $49/mo (or $24.99 / $39.99 billed annually).

13. Public scorecard live + descriptive signal labels

    improvement

    v0.1.1 · 2026-04-24

    • ·Public scorecard goes live: every top-10 we publish is back-checked against the next-day move alongside SPY for the alpha column. No cherry-picking.
    • ·Signal labels (HIGH CONVICTION, STRONG SETUP, CONSTRUCTIVE, NEUTRAL, CAUTION, WEAK) tightened to descriptive language so the score communicates the data rather than prescribing action.

14. Tapeline launches

    shipped

    v0.1.0 · 2026-04-22

    • ·Six-factor scoring methodology live with all six factors published on /how-it-works.
    • ·Scanner with one composite score and one plain-English Why on every US-listed ticker.
    • ·Watchlist with smart score-change alerts.
    • ·14-day Premium trial available with no credit card.
