FREQUENTLY ASKED

How does the algorithm work?

Nox Aeterna uses LightGBM machine learning to predict temperature distributions, then compares model probabilities against Polymarket bracket prices to find mispricings (edges). Trades are sized using the Kelly criterion.

What is the expected return?

Backtested at +55.96% flat ROI over 10 days with normalized prices and 2% fees. Past performance does not guarantee future results. Weather markets can be volatile.

Is there an iOS app?

The iOS app (Nox Aeterna) is currently in development. It will offer real-time signals, portfolio tracking, and direct trade execution on Polymarket.

How does autonomous mode work?

In autonomous mode, the algorithm automatically executes trades on Polymarket when it detects edges above your configured threshold. You set the risk parameters, the algorithm handles execution.

What markets are supported?

Currently 10 global weather stations: New York, Chicago, Miami, Seattle, London, Paris, Ankara, Tel Aviv, Seoul, and Buenos Aires. All on Polymarket temperature brackets.
