A critical factor in calculating accurate greeks so important for options analysis is creating a good volatility input to your options pricing model.

At ORATS, our Smoothed Market Values (SMV) options quotes uses an intensive process to create the best skew of implied volatilities that are then used to calculate accurate greeks and theoretical options values.

The SMV is based on the bid ask of all standard options and accompanying stock prices snapped 14 minutes before the close. Since options prices tend to deteriorate in quality at the close, we choose to base our quote delivery on near end-of-day options market quotes.

All optionable US equity options on all stocks, ETFs and indexes are included. For indexes, the implied futures price and spot price is included for each option based on the expiration. Each option's volume and open interest are also included. More information on the process is here.

DELIVERY

On-going SMV Quote zip files are available by FTP with updates by 9:30 pm EST.

The initial bulk download can be by FTP or AWS S3.

For S3, you provide us S3 bucket info, authenticate, and we bulk copy quotes zip files into your S3 bucket. On-going data can be downloaded using FTP only.
