Altair
altairMeasures short-term liquidity dynamics, slippage and market order imbalances.
How the factor is constructed
Altair is a short-term liquidity metric that captures intraday market dynamics. The data is collected in real time and aggregated from the most reputable exchanges. Altair is a high-turnover factor that benefits from smoothing to reduce transaction costs.
The universe consists of the most liquid and actively traded assets, identified on a rolling basis and survivorship-bias free. Positions are scaled by the inverse of rolling volatility; the factor is available point-in-time with hourly updates.

Putting Altair to work
There are two ways to take Altair from factsheet to live book: overlay it as a sleeve on the portfolio you already run, or use it as a building block in a standalone multi-factor portfolio. Both paths are documented in short, runnable notebooks that work out of the box against the public demo key — no signup required.
Add Altair to an existing portfolio
Size a Altair sleeve alongside your current book and quantify what it changes: correlation to your existing returns, then CAGR, volatility, Sharpe and maximum drawdown before and after the blend. One parameterized notebook runs for any factor — swap in Altair, then bring your own daily returns as a CSV or start from the built-in demo book.
Build a portfolio from scratch
Construct a market-neutral multi-factor portfolio from the ground up: ensemble the raw signals, apply inverse-volatility weights with a per-asset cap, and backtest net of transaction costs. The default factor list reconstructs the 7 Factor Composite — Altair is one of its seven constituents, so its contribution is in the blend from the first run.
