Features of the Data
With 4500 symbols and 12 years of history, it can be a daunting task to figure out what to use. We organize the data in the following way:
- Strikes — One row per options strike with bid ask quotes from snapshot of market data 14-minutes before the close (the time we think is the latest in the day where the quotes are still of high quality, not deteriorating and widening as they do near the close).
- Moneyness — One row per expiration showing implied dividends, implied volatility skews and earnings information.
- Core — One row per stock containing a wealth of volatility, volume and important calculations.
