Console · DuckDB-WASM

SQL console

Query a slice of the research database directly in your browser. The same DuckDB engine the platform runs on, compiled to WebAssembly, loads the tables on the right from Parquet files and executes whatever you type. Nothing leaves your machine and nothing here writes.

How to read this

These are slices of the platform's DuckDB file, exported as Parquet by the same script that built this demo: the full predictions, live_book, daily_signals, backtest_daily, research ledger and registry tables, and date-bounded cuts of the big ones (prices from 2024, all 25 indicators for the last 63 sessions, monthly universe snapshots since 2005). Row counts and the exact bounds are in the table list.

Two rules from the platform carry over. A prediction row whose scored_at date is later than its score_date was scored after the outcome existed and is not out-of-sample evidence, whatever its source stamp says. And every statistic in research_results carries its standard error and n; read those before the means.

The engine runs in a Web Worker; the runtime (about 8 MB) comes from the jsDelivr CDN on first use and is cached by the browser. If it cannot load, the rest of the demo still works.
