GEX levels study for thinkorswim

The FinzData GEX Levels study plots the gamma flip, call wall and put wall on the price chart and shades the gamma regime. Gamma flip is price where dealer gamma changes sign. Above dealers are long gamma and moves tend to be damped. Below dealers are short gamma and moves can accelerate. Call wall is the strike with the largest call gamma and often acts as resistance. Put wall is the largest put gamma and often acts as support.

thinkscript cannot load outside data, so you type the day's three numbers from https://finzdata.com/gex-levels-today into the study settings. The free daily levels page covers SPX, SPY, QQQ, NDX, IWM, RUT and the most active stocks and ETFs. This makes gex levels actionable inside thinkorswim charts.

Futures open interest study

FinzData Futures Open Interest uses thinkorswim's own data to show open interest on the chart with the price open interest regime of every bar. The study labels long buildup, short buildup, short covering and long unwinding directly on price.

Open interest context helps interpret moves in futures. The study is pure thinkscript and requires no external feed. It works with any futures chart in thinkorswim. Combine it with price action and volume for a clearer read on positioning. The indicator is part of the free thinkorswim indicators package from FinzData.

• Price open interest regime per bar
• Long buildup and short buildup labels
