About DJX options GEX
Options on the Dow Jones Industrial Average trade on Cboe under the DJX symbol and are based on one-hundredth of the index level. They are European-style and cash-settled. Because of that scaling, the strikes and levels on this page are quoted on the reduced DJX basis rather than in full Dow points. The chain can be sparse, with only a few strikes carrying meaningful open interest.
This page combines every DJX expiration into one gamma exposure curve, showing the gamma flip, the heaviest long-gamma strikes and the heaviest short-gamma strikes.
In a small chain, few strikes carry real weight, so treat DJX levels as broad areas rather than precise lines. The Dow is price-weighted: each of its thirty members counts according to its share price, not its market value, so a move in one expensive stock can shift the index noticeably. That means a DJX level can be crossed on news from a single company, whatever dealers are doing. The companion view is the DIA page, the ETF on the same index. Use DIA to confirm a zone and DJX to see whether index traders agree, and check the heatmap to see whether a sparse peak has lasted.
The numbers are refreshed once a trading day, after the US market shuts, from end-of-day open interest from the latest available report.
FAQ
What is DJX?
DJX is the Cboe symbol for options on the Dow Jones Industrial Average, the price-weighted index of thirty large US companies. As index options, they settle in cash rather than in shares.
Why can the DJX profile look sparse?
When only a limited number of positions are open, just a handful of strikes carry meaningful gamma and the gaps between them are wider. Read DJX levels as broad areas and confirm them on the DIA page.
Should DJX be read together with DIA?
Yes. DIA is the ETF that tracks the same Dow index, so comparing the two pages shows whether a zone is supported by index options, ETF options, or both.
When are DJX levels published?
Once per trading day, after the US close. They are derived from end-of-day open interest from the latest available report on all listed DJX expirations, so they do not move during the session.
Levels are derived from end-of-period options open interest and are published once a day. Educational information, not investment advice.
