Price gap
CoinGeckon/aSerializedn/a
The figure is the gap between what a price API printed and what the exchanges were quoting when the answer arrived, so it bundles two things: how the API builds its price and how old that price is. A feed refreshed every minute carries up to a minute of market drift into its gap, and that is intended, because it is what a reader of the API receives. The signed bias column separates a constant offset from noise.
