FINANCIAL MODEL / EXPERIMENTAL
A financial model.
Built to be
measured.
One shared model for public equities.
Two interfaces. An inspectable record.
v0.2 introduces a shared probabilistic path forecast for multiple financial questions. The original v0.1 app/API model and historical prediction records remain available.

One model.
A complete path to measurement.

A probability means more when you can see when it was made, which model made it, and what happened next.

Record the prediction.
The estimate, model version and creation timestamp identify what the model said before the outcome.

5 TRADING DAYS
Let the horizon pass.
An open prediction is still open. Its future return is not yet an observed result.
03OUTCOME
AFTER THE HORIZON
Observe. Compare. Evaluate.
Compare the recorded estimate with the realized return. Historical testing and prospective results remain separate.
INSPECT ACTUAL PREDICTIONS
Explore predictions A record starts with a real request.
Open a production prediction to inspect its timestamp, model version and reference price. Return to the same record to compare its estimate with the resolved outcome.
v0.1 / HISTORICAL BASELINE
Run it. Record it.
Return to measure it.
Run the production model, then open its prediction ID to inspect the persisted record. The outcome follows after 5 trading sessions.
Open v0.2: one forecast, many questions
