A third perpetuals venue, kept apart from the other two on purpose.
Why it is not folded in with the others
Three differences, each of which would corrupt a shared table:
- Funding settles hourly. A complete day is twenty-four intervals, not
three. Annualising it with the other venues’ factor overstates by eight, and
the two numbers look equally plausible side by side.
- Open interest has no history at all. The venue reports it as it is now.
There is nothing to backfill and never will be.
- History begins 2023-05-12, the venue’s own start. An empty answer for 2021
is correct rather than a failure.
Folding these into the same day rows would need one “is this day complete” test
that has to know which venue wrote each row.
What it gives that the others do not
Liquidations with the address. No centralised venue publishes who was
liquidated. Here each forced close carries the address, the fill price, the mark
price at the time, whether it was taken at market or backstopped, and which
HLP vault absorbed it.
Live state per coin, not just BTC and ETH: the current hourly funding rate,
open interest, oracle and mark price, and the premium between them — which is
what funding is computed from and the cleanest single reading of whether the
perpetual is trading rich.
It records forward only
Because neither series can be fetched retrospectively, this stream contains
exactly what has been watched and nothing earlier. Both responses say so.
A reader cannot tell a short history from a quiet market by looking at the rows.
That is why the answer states when the record begins rather than leaving it to
be inferred.
Status
The endpoints are deployed and behind the same key as everything else. The
watcher that fills them runs on a schedule; until it has, they answer with what
is missing and why rather than with an empty list.
