Reading the quotewhat the numbers mean

These are our quotes, not an order book. No venue streams a DXK book, so bid and ask are mid minus and plus a half-spread we build from the risk each derivation step carries. mid is the reference price; spreadBp is the full bid-to-ask width in basis points.

spreadBp is not constant — watch it. It widens as the underlying venue books widen, and it widens further when the euro reference has gone a long time without a fresh print. A rising spread is the honest signal that a quote is carrying more risk.

basis on DXK/EURC. "live" means the euro basis is being measured from fiat-euro books. "unhedged" means none were available, so the quote falls back to the euro reference itself and the spread widens by ~4bp to cover a basis we cannot currently see. The price stays usable either way; it is just less informed.

spreadBp	number	Full bid-to-ask width, basis points.
halfSpreadBp	number	Half that, for convenience.
decimals	int	Suggested display precision for this instrument.
tradable	bool	`false` when an input is missing; mid, bid and ask are then `null`.
