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.

Free account required

Officer and director trades in their own stock, straight from Form 4 filings.

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.
