London Strategic Edge | The Largest Free Archive of Market Data

London Strategic Edge is building the largest free archive of market data. The databank serves 5.5 trillion ticks across 246,000+ datasets: stocks, options with greeks, forex, crypto, futures, ETFs, commodities, indices, bond yields and 41,800+ macro economics series for 211 countries, some back to 1900. Everything is free to browse, and our own markets are free to download as Parquet or CSV with one free key. The same platform offers free strategy backtesting, machine learning price forecasting (LSTM, XGBoost, CatBoost, Random Forest), live charts and options analysis across 15,000+ instruments. The free plan costs nothing and needs no credit card; paid plans add exchange data such as Nasdaq TotalView and CME Group and raise the limits.
