How it works

From notebook to production

  1. 01

    Pick the metrics

    Browse the catalog and pull point-in-time microstructure metrics — no L2 reconstruction, no tick archive to maintain.

  2. 02

    Run the notebook

    Every notebook runs end to end on preview data with a free account, in the browser or through the CLI.

  3. 03

    Plug it into your stack

    Swap the preview key for your own and the same code pulls the full history through the Python package or the API.

Intro to Aperiodic Flow Metrics

Find new alpha

This notebook introduces order-flow analytics with the `aperiodic` Python package. We focus on a single large-cap instrument — Binance BTC perpetuals (`perpetual-BTC-USDT:USDT`) — over the exact six-month window from September 1, 2025 through February 28, 2026, using 1-hour observations.
