ORB by Toby Crabel is an old indicator, it is not worthy anymore, why, because you could see now in Gamma volume data if the market will break the opening range or not. For me it is an old stuff when data was not available before and theory was made and become a guide.
How do you use Gamma volume data?
How would you structure/ combine your indicators to see all that at once? Do we have one here that would help?
Options volume shows where trades occurred.
Open interest shows where risk remains and where hedging pressure may emerge as price approaches those levels.
For your platform and GEX logic, Volume answers the question, "Did positioning change today?"
OI answers, "Where will positioning matter tomorrow?"
Options volume explains where positioning changed and why a move likely occurred.
Open interest is conditional — it becomes important only when price approaches those strikes, because that is when hedging pressure can be activated.
I tend to use both the volume and open interest, to some degree I think of them as the volume being the "past" and the Open Interest being the "future".
More times than not, Open Interest will fall in a support and resistance zones. In my opinion, you should always mark your GEX levels on your chart, especially the positive and negative transition zones!!!
Great subject, so we have gamma values study for tos, can share?
Here is something that in a way replaces having to draw your GEX data manually.Great subject, so we have gamma values study for tos, can share?

Gamma, the fun and exciting Greek. See it like wind entering a tunnel, as it gets closer and closer to the entrance, the faster wind gets pulled. Another analogy respecting the influence of the other Greek data, its like an electromagnet, and plus the closer it is pushed and pulled within the ranges effects gamma numbers. Theta is time decay. Delta a percentage for possibilities, the effect of Vega, and Rho (interest factor), so I put together the "Pimple" indicator for the Gamma Effect. Every time it sees an increase to gamma, it plots a "squeeze" bubble, even for sells.How do you use Gamma volume data?
Good thoughts!This is a common misunderstanding among newer traders.
Actually, some of the oldest strategies are still the best precisely because they measure behaviors that never disappear.
Many of the new talking‑head strategies — and the idea of relying only on Gamma volume — push traders into chasing microstructure without any macrostructure framework to anchor their decisions.
That’s backwards.
You always start with macrostructure, then refine with microstructure.
Tools like the Opening Range Breakout define the framework of the day: where the auction first balanced, where liquidity concentrated, and where the market accepted or rejected price.
Only after that structure is mapped does it make sense to layer on microstructure tools like Gamma volume, order flow, or options positioning.
ORB is not “old stuff” — it’s an essential structural map.
