Binance’s SKHYNIXUSDT perpetual uses vendor data for one SK hynix Inc. share and a separate FX rate, while the contract is quoted and settled in Tether (USDT).
The contract specification identifies the share as a common stock listed on Korea Exchange under ticker 000660 and priced in South Korean won. The KRW/USD rate is a distinct input to the Price Index. Both feeds come from third-party vendors, and Binance says the providers may vary with the market session.
The stock ticker and contract symbol identify different instruments: 000660 refers to the listed share, while SKHYNIXUSDT is the perpetual contract. Binance describes the contract as available 24/7.
Binance guidance says a USDT/KRW conversion has applied to Korean-equity perpetuals since Aug. 7. When the local share market is closed, including on weekends and holidays, the index calculation switches to Orderbook EWMA mode, a smoothed method based on order-book data.
