BSBR and its option levels over the last year
The close, with the call wall and the put wall (the strikes the option book is heaviest at) and the gamma flip (the price where dealers’ net gamma changes sign). Each line is that day’s reading, not a level looked back on.
Not in the picture: Gamma flip 3.08 (below the picture).
Implied against realised volatility
What the options charge for the next 30 days, against how much BSBR actually moved over the last 20. A gap between the two is the market’s price for uncertainty.

How to read these figures
Gamma exposure (GEX)
How much dealers must buy or sell to stay hedged for each 1% move in the price. Long gamma means they trade against moves and dampen them; short gamma means they trade with moves and can amplify them. It is estimated from open interest and an assumption about which side dealers are on.
Call wall and put wall
The strikes where call and put open interest is heaviest within reach of the price. Prices often slow, or get pinned, near them into expiry; they are where a lot of hedging sits, not a guarantee.
Gamma flip
The price at which net dealer gamma changes sign. The same book acts as a brake above it and as an accelerator below it.
Max pain, IV rank and the priced move
Max pain is the strike where an expiry’s options are worth the least in total. IV rank places today’s implied volatility between the lowest (0) and the highest (100) of the last year. The priced move is what the options charge for the period, as a share of the price.
