Stocks, ETFs, options, futures, FX, crypto, fundamentals & filings — point-in-time, survivorship-bias-free, delivered in real time.

Why legacy market data breaks
Terminals bundle UI + data → hard to integrate, impossible to automate
Backtests lie without point-in-time fundamentals and delisted tickers
Licensing is opaque, pricing scales with seats, not value
Normalization errors and corporate actions silently corrupt results
Eulerpool was built from scratch as API-first infrastructure.
Point-in-Time Accuracy
Every data point reflects exactly what was known on that date. No look-ahead bias. No data leakage. Your backtests finally work.
✗ Others: $2.89T (today's value)
Zero Survivorship Bias
We include every company that ever existed—bankruptcies, delistings, mergers. See the real market, not just the winners.
✗ Others: ~380 companies (survivors only)
