EVERY CALL PUBLISHED BEFORE THE OPEN · GRADED IN PUBLIC

An AI that calls the market.
And proves it.

Every market morning, BrainStock publishes its stock calls.
Real prices grade them in public five days later.

Then time passes.
It grades itself.

The blue line is the promise. Real candles walk out to meet it. When the window closes, the call is scored against the real price: hit or miss, on the record.

03 · The mechanism

How a call becomes a receipt.

No edits. No deletions. No do-overs. The same three steps, every trading day.

01
Published before the open
The net scans hundreds of stocks and posts its calls: ticker, direction, target. Timestamped while the outcome is still unknown.
02
The market answers
Five trading days pass. Real closes walk out to meet the forecast. Nobody at YN can touch the call while it resolves.
03
Graded in public
The close is compared to the call. The result lands on the public record forever, misses included.

The grading rules, data sources, and calibration math are all public. Read the methodology →

04 · The offer

You only pay when the AI is right.

No subscription. A winning call costs $0.25 at month-end. A miss costs nothing. Never more than $20 a month.

$0.25
per winning call
Charged only after the call is graded a hit against real closes.
$0
per miss
A wrong call costs you nothing. A cold month costs less, automatically.
$20
monthly cap
The most a month can ever cost, no matter how hot the AI runs.

Save a card, get charged nothing today, settle at month-end only for calls that hit. Cancel anytime. Educational research, not financial advice.
