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.

How this is calculated, and what it cannot see

A contract is flagged when today's volume approaches or exceeds its open interest, the position is worth at least $40,000, and at least 150 contracts changed hands. Open interest is what was outstanding at yesterday's close, so volume above it means the flow cannot all be closing — something is being opened.

The score weights four things: volume against open interest, dollar notional, volume against the rest of that chain, and where the last print sat inside the bid/ask spread.

What it cannot see. Volume here is a daily total, so ten small orders and one large one are indistinguishable — this is not block or sweep detection, which needs exchange-level time and sales. The print column compares the last trade to the current quote, which is a proxy for who was the aggressor, not a tagged flag. Quotes are delayed. A single large trade can be a hedge, a roll, or one leg of a spread, and none of those mean what a naked directional bet would mean.

Contracts trading at or above their open interest, ranked by notional and where the print landed.

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.
