Frequently asked questions

Where does the data come from?

Live options and stock data from the Massive.com feed (Polygon-compatible), earnings dates from Finnhub, and OptionScout's own daily captures of gamma exposure and implied volatility. Every page says when it was last read, in Eastern Time.

Is any of it estimated?

No. When a quote, chain or calendar entry is missing the page says so and shows a dash. The only model numbers are implied volatility (solved from option prices) and the expected move (the at-the-money straddle or an IV-based range), both labelled.

Which tickers are covered?

The 161 stocks and ETFs with the most options trading. Each has a hub at /stocks/<ticker> linking its earnings, chain, put/call, expected move, IV rank, GEX and max pain pages.
