Kraken

Kraken is one of the three exchanges Angolin ingests from, alongside Binance and OKX, and the one with the longest history. Its candles can be queried on their own, or combined with the other exchanges into the aggregated series — see Methodology for how.

Coverage

OHLCV (open/high/low/close/volume) candles at three intervals — 1d, 1h and 1m — for about 1,750 spot pairs, across every quote currency Kraken lists. Pairs that were delisted keep their full history. The Catalog endpoints list every pair with its first and last candle.

Data source

History comes from Kraken's downloadable OHLCVT archive, published as a full release plus quarterly updates, which keeps delisted pairs and serves every interval natively. Kraken's public API only returns the latest 720 candles of a pair, so it is used for the recent 1d and 1h candles only, refreshed on a regular schedule.

History

Every pair starts at its first candle on Kraken — September 2013 for the oldest. 1d and 1h run up to the latest complete candle. 1m runs up to October 1, 2026 for now: minute candles come from the archive only, and extend with each quarterly release.

Universe

The Universe endpoint and downloads tell which pairs Kraken listed, hour by hour. Listed means tradable: a pair Kraken gives the status online, post_only, limit_only or reduce_only (which restricts margin, not spot), whether it traded or not. A pair in cancel_only is on its way out and no longer counts.

Since October 27, 2026: observed

Kraken's list of spot pairs is recorded every hour, as Kraken returns it. A listing or a delisting shows up within the hour it happened.

Before: reconstructed

Nothing recorded Kraken's listings before that hour, so the past was rebuilt from three sources, about 1,790 listing periods from September 2013:

  • The candles give the starts: a pair is listed from its first candle. Kraken only builds a candle when a trade happens, so a quiet stretch proves nothing, and its archive misses a few stretches of its own (a whole quarter for some pairs): those are bridged, not read as delistings.
  • Kraken's delisting announcements give the ends, to the hour, for about 300 periods: the time trading was disabled. They matter here because Kraken's archive drops the last months of a pair it delists, so a pair's last candle is not its delisting.
  • Archived snapshots of Kraken's own list of pairs and of its 24-hour trade counts (from the Internet Archive, 2021 to 2026) end the others at the last time Kraken still listed the pair, and check the whole: the reconstruction agrees with 99.98% of what these snapshots show.

Known limits

  • Before 2021, pairs Kraken delisted early (BSV, ICN, DAO…) are missing: its archive no longer holds them, and the oldest usable snapshot is from April 2021. The universe of those years is incomplete, biased toward pairs that survived.
  • Ends without an announcement (about 120, mostly before 2025) are the last snapshot that still lists the pair: the real delisting came later, by a few weeks to a few months, before the next snapshot.
  • Pairs listed but never traded have no candle: their period comes from the snapshots alone, from the first one that lists them.
