Hyperliquid spot trades its unit tokens, so spot symbols are `UBTC-USDC`, `UETH-USDC`, `USOL-USDC`; the perpetuals are `BTC-USDC-PERP`, `ETH-USDC-PERP`, … on `hyperliquid-future`. Both quote in USDC only. Symbols are case-sensitive, and Hyperliquid's thousand-unit contracts keep the venue's lowercase prefix: `kPEPE-USDC-PERP`, `kBONK-USDC-PERP`, `kSHIB-USDC-PERP`. Kraken Futures drops the venue prefix: `PF_XBTUSD` → `BTC-USD-PERP`, `PI_XBTUSD` → `BTC-USD-PERP-INV`, `FF_XBTUSD_260925` → `BTC-USD-2026-09-25`; Crypto.com `BTCUSD-PERP` → `BTC-USD-PERP`; Bitfinex `BTCF0:USTF0` → `BTC-USDT-PERP` (its `UST` is USDT); Bitfinex's paper-trading pairs are served under their own names on both spot and future, `TESTBTC-TESTUSD` and `TESTBTC-TESTUSDT-PERP`.

The dates above are for trades and candles (OHLCV). The **option-chain** dataset (`api.option_chains` — 5-minute IV / greeks snapshots) is separate and more recent: available from **2026-05-12** across Deribit, Binance, OKX, and Bybit. For option history before that date, use the option **trade** tape (`deribit-option`, from 2016-11-29) and recompute IV / greeks from the premium.

#### Data delay
