What you get on the chart
- FinzData Open Interest: total open interest across every contract of a futures market and the front month's, one value per trading day, for all 139 markets since 2007.
- FinzData GEX Levels: the gamma flip (where dealer gamma changes sign), the call wall and the put wall, drawn on the price chart from the prior session's close, so there is no look-ahead.
Behind each indicator is the same point-in-time data you get from the FinzData API: open, high, low, close, volume and open interest for every contract; net, call and put gamma, call and put open interest, the put/call ratio, at-the-money implied volatility and the number of contracts behind every GEX row.

Questions
Are the indicators free?
Yes. The indicators are free to download and use. A free FinzData API key (just an email) covers the last 30 days of futures and daily GEX; the full history is sold once in the shop and the same key unlocks it.
Which data feeds do they work with?
Any feed your platform is connected to, including Rithmic, CQG, Interactive Brokers, Kinetick and Denali. The indicators read FinzData directly, so the feed only supplies your price bars.
Is there look-ahead in the GEX levels?
No. Each bar shows the gamma flip, call wall and put wall computed at the prior session's close, the levels a trader actually had that day.
Which markets are covered?
Open interest for all 139 FinzData futures markets (ES, NQ, CL, GC, ZN, 6E, FDAX and more); GEX for single stocks, ETFs and the major indexes such as SPX, NDX and RUT.
