Options analytics
Every US option contract since 2012, turned into positioning, sentiment and squeeze signals.
The options market often moves before the stock does. ORTEX captures the full US option chain every trading day, around 1.8 million contracts across more than 5,500 underlyings, and has kept every one since 2012. On top of the raw chain sit the signals desks actually use: put/call ratios, moneyness, implied volatility, dealer gamma positioning refreshed through the session, unusual flow, and a squeeze score that reads options and short interest together.
option contract records on file: every listed US contract, every trading day since 2012, ready for backtesting any options signal across fourteen years.
