What this is, and what it is not
These are SEC Form 4 filings — officers, directors and 10% owners reporting their own trades in the company's stock. Filing is due within two business days of the transaction, so this lags reality by days, and the provider adds its own lag on top.
A sale is not automatically bearish. Executives sell on scheduled 10b5-1 plans, to cover tax on vesting equity, and to diversify. Purchases with cash are generally the more informative signal, and they are far rarer.
This does not include congressional or senate trading. That comes from STOCK Act disclosures filed with the Senate eFD system and the House Clerk, which this data source does not carry.
Officer and director trades in their own stock, straight from Form 4 filings.

Unusual options activity
That is the normal state — most contracts trade well inside their existing open interest.
Contracts trading at or above their open interest, ranked by notional and where the print landed.
Options analytics
Max pain is the strike at which the largest dollar value of open contracts expires worthless. It describes current positioning; it is not a forecast and it moves as open interest changes.
Put/call ratios, max pain, implied volatility skew and where open interest is concentrated.

Every listed expiry, both sides of the book, with volume, open interest and implied volatility.
Trailing performance
Price return only. Dividends are not reinvested, so total return on a dividend payer will be higher than shown.
Fundamentals
Short interest
Exchanges publish short interest twice a month with a settlement lag, so this is roughly two weeks behind. Days to cover divides shares short by average daily volume — it estimates how long covering would take, not whether it will happen.
Valuation & profitability ratios
Fourteen ratios including P/E, PEG, EV/EBITDA, margins and return on equity.
