Verify the record

A stock screener whose record you can download and check yourself.

Most screeners hand you a number and ask you to trust it. You cannot see the method, and you cannot see how the output has actually done. Tapeline publishes both: the six factors behind every score, and an append-only record of every daily top-10 pick, back-checked against SPY the next session — including the days it went nowhere.

Three rules that make the record checkable, not decorative

A track record is only worth something if the person publishing it can’t edit it after the fact. These three rules are what let you treat the archive as evidence instead of marketing.

Append-only

Every entry is written once and never edited or deleted. If the method changes, the change is dated in the changelog and the old rows stay exactly as they were recorded. There is no hindsight editing and no quiet re-scoring.

Losing days kept

The sessions where the top-10 went nowhere sit on the page in the same styling as the sessions that went well — same weight, same size, no trophy on the good ones and no burial of the bad ones. Removing them would defeat the point of publishing at all.

Checked the next session

Each pick is scored at one session's close and evaluated at the next session's close, and its move is set beside SPY's move over the same window. The comparison is the same arithmetic for every row, so you can reproduce it from the raw file.

Verify it yourself, in three steps

1
Download the raw record. Take the whole archive as a spreadsheet or as JSON — no login, no card, nothing gated.
Download the scorecard (CSV)Download the scorecard (JSON)
2
Re-run the arithmetic. Every row carries the pick’s move and SPY’s move over the same next session. The comparison is the identical calculation on each row, so you can reproduce the summary — and count the losing days for yourself — straight from the file.
3
Spot-check a single ticker. Open the frozen record for any symbol — for example /scorecard/AAPL — and confirm the row on the page matches the row in your download. Cross-reference the live factor readings on its ticker page and the weighting on how it works.

What’s in the download

Each row is one recorded pick. These are the fields you can pull and re-check — descriptive readings, not a performance summary.

Field	What it is
Date	The session the pick was recorded.
Symbol	The ticker, as it was ranked that day.
Tapeline Score	The original 0-100 composite, frozen at record time.
Signal label	The band the score fell into that day.
Six factor readings	Trend, Relative Strength, Fundamentals, Smart Money, Macro, Momentum — as scored.
Next-session move	How the ticker moved the following session, beside SPY's move over the same window.

The record is deliberately raw rows and plain counts — nothing annualised, compounded or turned into a hypothetical account balance. The exact column definitions live alongside the export in the data sources page.

What the record currently shows

The sample is small and the result so far is close to a coin flip against SPY — it sat below an even split for weeks. That figure stays off this page and out of every headline on the site by design, so the presentation reads the same whether the number is flattering or not. The numbers, with the sample size next to them, are on the scorecard.

Why a checkable record is the whole point

If nobody outside the company can see the method and nobody can see the record, the score is unfalsifiable — and an unfalsifiable number is a marketing asset, not an analytical one. Publishing the archive, keeping the losing days, and handing you the raw file is what turns “trust us” into “check us”. That is the entire difference Tapeline is built around.

The longer version — the five questions worth asking of any scanner before you pay, and how most of them quietly fail the record test — is in how to evaluate a stock scanner you can actually trust. The reasoning behind publishing losing days at all is on why, the named factors are on how it works, and the honest list of what this product is bad at is on limitations.

Verifying the record — questions

Can I verify Tapeline's record myself?

Yes. The full scorecard is downloadable as CSV or JSON with no login and no card. Each row is one top-10 daily pick with its original Tapeline Score, its signal label, its six factor readings, and how the ticker moved the next session beside SPY's move. You can re-run the comparison yourself from the file.

What does 'append-only' mean here?

Entries are written once and never edited or removed. When the methodology changes it is dated in the changelog and past rows are left as they were first recorded — so the archive can't be quietly cleaned up to look better than it was.

Does the scorecard keep the days the picks lost?

Yes. Losing sessions are published in the same styling as winning ones, with the sample size shown next to the summary. Nothing is deleted after the fact. Publishing only the good days would make the record a marketing asset instead of a checkable one.

How is each pick checked against SPY?

A pick is scored at session N's close and evaluated at session N+1's close. Its move over that window is placed beside SPY's move over the same window. It is the identical calculation on every row, which is what makes the archive reproducible from the raw download.

Is the data free to download?

Yes — CSV and JSON, no account required. The endpoints are on Tapeline's own origin (/api/scorecard.csv and /api/scorecard.json) so you can script against them directly.

What can't the record tell me?

It is a small, growing sample, it is descriptive rather than predictive, and it is not advice. A high score is not a recommendation, and the honest list of what a six-factor screen is bad at lives on the limitations page. Read that before you pay for anything.
