Measured, not quoted
How much a price actually moved.
Tremolo lets two sides trade how much a price will shake. One side earns if the market stays calm, the other if it storms. Both put up their maximum loss on day one - so nobody gets liquidated and nobody ever owes more. Liquidity providers use it to insure the volatility bill they already pay; traders take the other side and get paid for carrying it.
Every volatility figure on chain today got there by being asserted. Tremolo computes its own, from the record the chain already keeps.
