Five thousand companies. Your plan needs about eight.
The screener narrows the whole market down to companies that pass the checks you care about: real profit, manageable debt, a business big enough to trust. What survives goes straight into a plan, not into a spreadsheet.
87 companies passed. The strongest four:
One tap sends this list into the builder, where it becomes a plan the engine can test on real history.
How the narrowing works
Each filter is a plain question about a company’s health. Stacking them is how thousands become a handful.
Start from the whole market
The screener begins with more than five thousand listed companies, each with its financial statements already loaded: what it earns, what it owes, and how big it is.
Ask health questions, in plain words
Does the company make real profit on the capital it uses? Is its debt small compared to what it owns? Is it valued sensibly for what it earns? Every filter is a question like that, and Stax explains each one as you add it.
Watch the count fall
With each question, the count drops: five thousand becomes a few hundred, then a few dozen. What remains is a list where every company passed every check you set, with the numbers shown for each.
Send the survivors into a plan
The short list is a beginning, not an answer. One tap moves it into the builder, where those companies become a trading plan the engine can replay over years of real prices before it runs.

shown side by side
The verdict, in plain words: this plan grew a $10,000 practice account to $13,850 over five real years, and you can open every one of its 214 trades to see why it bought or sold.

A list you cannot test is just a longer hunch.
Most screeners hand you a table and wish you luck. Stax treats the screen as the first move of a bigger machine: the companies you keep flow into rules for buying and selling, and the whole thing gets proven against history before an account is touched.
That difference matters most when a screen looks brilliant. Passing your filters today says nothing about how a plan built on those companies would have survived a rough year. The engine answers that question with a replay, trade by trade.
What the replay showsFrom the whole market to a working plan
- 5,000+
- listed companies checked against every filter you set
- 1 tap
- to turn a short list into a plan the engine can test
- 0
- spreadsheets between the screen and a working plan
A screen reads today’s financial statements. It finds healthy companies, not future winners; the history test exists to check what a plan built on them would have endured.
Questions people ask
What kinds of filters can I use?
Questions about profit, debt, valuation, size, and cash generation. Each one is written in plain language, and Stax shows what the underlying number means for the company before you commit to it.
I do not know what a good filter looks like. Now what?
Start from a template that already carries a sensible set of checks, or describe what you want in the chat and Buddi proposes the screen. You can change any question, say from profit above 15% to above 20%, and watch the count move as you do.
What happens to the companies that pass?
They become the stock list of a plan. The builder writes the buying and selling rules around them, the engine replays it all on real history, and the finished plan can practice in a slot with simulated cash.
How fresh are the numbers behind the filters?
They come from company financial statements, which update when companies report each quarter. The screener always works from the latest reported figures and shows you the values it used.
Your short list is a few questions away.
Set a few health checks, keep the companies that pass, and send them into a plan the engine can test on real history.
