DEBYKO

Crypto derivatives data from 2 venues — 12 listings collected — asked about in one language.

Every value carries the venue that published it, the time it was received and its age. A missing value is never a zero, and venues are never averaged.

What this is

any(venues where funding_8h > 1bps and age(funding) < 2m) where base = BTC

That is DQL. It selects instruments by what several venues are doing at once, and every number it returns comes back with the venue that published it, when the platform received it, and how old it was at the moment of the question.

Four things that will not happen to your data

A missing value is never a zero. A field a venue does not publish is absent, and the answer says which of five things it is: present, stale, missing, not published, or not collected.

Venues are never averaged. There is no “the price of BTC” here. There is what each venue published, and the age of each.

Values come back as the venue published them. No rounding, no rescaling, no re-serialising on the way through. A derived figure says it is derived and carries the values it was computed from.

A gap stays a gap. History is stored with its holes intact. A period nobody quoted is empty, never interpolated and never carried forward — a carried-forward price is a measurement that was not taken.

Start without a key

Coverage, the catalogue and the parser are free to read, because you should be able to see what exists and what a query may ask before deciding to pay for answers.
