INSIDE THE GUIDE
Practical concepts and decision checks.
Expose the assumptions
Public GEX estimates generally combine open interest with pricing assumptions and a view of who is long or short. Different models can disagree.
Treat levels as context
Large strike concentrations may matter, especially near expiration, but price, volatility, liquidity and news can dominate.
Use scenario language
Frame positive or negative gamma as a conditional market-mechanics scenario rather than a certain outcome.

Before you buy.
What is a gamma flip?
It is an estimated level where modeled aggregate gamma changes sign. The result depends on data and assumptions.
Does high gamma guarantee pinning?
No. Pinning is a possible behavior, not a guarantee, and other flows can overwhelm hedging effects.
Is this a trading signal service?
No. It is an educational guide to interpreting gamma concepts and model limitations.
