PredixLab

PredixLab is a US stock analysis platform for self-directed investors. Built on daily data and updated after the US market close, it brings a market overview, daily quantitative signals, a multi-factor stock screener and unusual options activity for S&P 500 and Nasdaq-100 stocks into one dashboard.

Daily signals from LightGBM models that turn daily scores into sparse turning-point events (Pivot) and rank stocks against each other (AlphaRank), with expanding-window walk-forward validation and per-trade cost assumptions in backtests.

The signal, backtest, API and dashboard code is open source (Apache-2.0) at github.com/predixlab/predixlab-signals. Market data is not included; data collection and options analysis run as part of the hosted service.

Key capabilities:

• Daily US stock signals (LightGBM-based Pivot events and AlphaRank rankings) with signal history
• Walk-forward out-of-sample evaluation and backtesting scripts (open source, Apache-2.0)
• Multi-factor US stock screener and market breadth overview
• Unusual options activity with contract-level open interest changes

Free plan: daily signals, options activity and signal performance with a 10-calendar-day delay. Premium: latest published data. A signal score is not a probability or a trade direction. For information only; not investment advice.
