What actually moves ZB

ZB is rates expressed as price: bonds rise when yields fall. It moves on the Fed, inflation data, and risk sentiment, and it's a cleaner macro instrument than most — but its fractional pricing (32nds) trips up traders who haven't internalized the tick math.

How the desk reads it

The desk reads ZB against the rates and inflation frame, with the regime gate distinguishing trending-rate environments from range-bound ones. Volume Profile works on bonds like anything else; the macro is the gate that decides whether the level holds.

Risk — read this twice

ZB is priced in 32nds — one tick is $31.25, and the contract moves on rate surprises. Know the tick math cold before you size, and treat CPI and Fed days as event risk.
