What Is a Gamma Strike?

Strike versus gamma exposure

An options chain contains many strikes. A structure map uses the positioning at those strikes to estimate where gamma-related sensitivity may be more concentrated. The strike is the coordinate; the estimated exposure is the interpretation layered on top of it.

A practical reading order

First identify the expiration and call/put side, then check open interest and activity around the strike. Finally compare the strike with the surrounding profile, current price, and other reference zones. A single strike should not be read in isolation.

• Use the timestamp and scope of the map.
• Compare concentration with nearby strikes.
• Check whether the data is sufficiently dense.

Limits of a strike label

A strike does not reveal the intent, entry price, hedge, or future adjustment of every participant. It also does not imply that price must stop, reverse, or move toward it.
