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.

Free account required

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.
