AMPL/USD price feed
AMPL rebases its entire supply daily: every wallet's balance is adjusted so the token can seek its price target. That makes it the strangest asset in this catalog to price, because here the price is only half of the position.

Book composition · auto-observed
A single active pool carries this book at the moment; the aggregate tracks it directly.
When the balance moves instead of the price
For every other asset on this site, holding still means your balance is constant and the price does the moving. Here the protocol moves the balance too, nightly, for everyone at once, in proportion to where price sits against target.
A price chart alone therefore understates everything that happens to a holder. The value of a position is price times a balance that breathes and only the price half is a market fact this feed can measure.
It measures that half properly: at the venues, block-stamped, at full resolution. What the supply did overnight is the protocol's ledger, not the market's.
