The screen
Sixteen disciplines, each one somebody else's published work.
Write the conditions yourself, or start from one that has been argued over for decades. Each names the book it came from and where ours differs, so you can check it against the original.

The deliverable
And then we keep checking, every night, and write only when one breaks.

Recovered: return on invested capital back above 20%

What people ask first
Questions
What does this product actually do?
It shows you a company's numbers with the source of each one attached: the formula, the inputs, the statement they came from, its fiscal year and its filing date. It lets you write down why you own the company, in your own words, together with the numeric conditions that have to stay true for that reason to hold. Then it re-tests those conditions every night against newly filed data and emails you the first night one of them fails.
How is this different from doing it in a spreadsheet?
A spreadsheet is as current as the last evening you spent on it. This reads the new filings every night, holds the reasons you bought beside the numbers that carry them, and writes to you the day one of those numbers breaks.
What is a guardrail?
One condition and one threshold, phrased as the statement that keeps your thesis alive. "Return on invested capital stays at or above 20 per cent" is a guardrail.
Where does the fundamental data come from?
The accounts each company files, standardised into comparable statements. Every statement carries its fiscal year, its period, its filing date and its reported currency, which is what makes the source trail on each figure possible.
Does it tell me what to buy or sell?
No. It gives you the filed figure, the formula behind it, the statement it came from and the date it was filed, so the decision is yours and you can say exactly why you made it.
Is there a trial, and does it need a card?
A 14-day trial of the entire product, and yes, it needs a card. Nothing is charged until day 15, when the plan you picked begins.
