Four chapters on what the numbers in FlowRadar mean, how they fit together, and where they stop being informative. Written to be read in order, but each stands alone. No prior options knowledge assumed beyond knowing what a call and a put are.
Why market makers hedge, and why their hedging is itself a large predictable flow. Long and short gamma regimes, call and put walls, the zero-gamma flip, and max pain.
Gamma is spread across expiries and strikes, and where it sits matters as much as how much there is. Includes the 0DTE distortion that makes headline gamma misleading.
Every column in the Scanner, and what it is actually measuring. Volume against open interest, sizzle, sweeps versus blocks, the direction arrows, and the composite score.
What signed premium measures, the four things no flow product can see, and why base rates matter more than the examples anyone shows you. The most important chapter here.
Same-day options build enormous gamma through a session and vanish entirely at the close. Here is why the wall that looked immovable at 2pm is gone tomorrow morning — and how to tell the difference before you trade against it.
