The Spot Oracle Price is computed as a weighted median of the sources below. Each source has a score; its weight is that score divided by the total score of the sources available at the time, so weights differ between market open and closing hours. | Source | Description | Score | Availability | | -------------- | ----------------------------------------------------------------------------------------------------- | :---: | :-----------: | | Pyth | [Pyth SPCX equity index](https://app.pyth.com/explore/Equity.US.SPCX%2FUSD) | 3 | Open hours | | Stork | [Stork SPCX oracle price](https://data.stork.network/assets/SPCXUSD) | 2 | Open hours | | Binance | [Binance SPCX index price](https://www.binance.com/en/futures/SPCXUSDT) | 1 | Open hours | | Bybit | [Bybit SPCX index price](https://www.bybit.com/en/trade/usdt/SPCXUSDT) | 1 | 24/7 | | Hyperliquid | [Hyperliquid SPCX index price](https://app.hyperliquid.xyz/trade/xyz:SPCX) | 1 | 24/7 | | OKX | [OKX SPCX index price](https://www.okx.com/trade-swap/spcx-usdt-swap) | 1 | 24/7 | | Lighter | [Lighter SPCX index price](https://app.lighter.xyz/trade/SPCX) | 0.7 | 24/7 | | Closing Price | Paradex SPCX spot price at the market closing timestamp | 0.5 | Closing hours | | Internal Price | EMA of the Paradex SPCX-USD-PERP mark price with a 1-hour half-life, initialised at the Closing Price | 0.5 | Closing hours | #### Open hours | Source | Score | Weight | | ----------- | :-----: | :------: | | Pyth | 3 | 30.93% | | Stork | 2 | 20.62% | | Binance | 1 | 10.31% | | Bybit | 1 | 10.31% | | Hyperliquid | 1 | 10.31% | | OKX | 1 | 10.31% | | Lighter | 0.7 | 7.22% | | **Total** | **9.7** | **100%** | #### Closing hours | Source | Score | Weight | | -------------- | :-----: | :------: | | Bybit | 1 | 21.28% | | Hyperliquid | 1 | 21.28% | | OKX | 1 | 21.28% | | Lighter | 0.7 | 14.89% | | Closing Price | 0.5 | 10.64% | | Internal Price | 0.5 | 10.64% | | **Total** | **4.7** | **100%** | ### Market hours SPCX options follow the equities session: open 24/5 from Sunday 8:00 PM ET to Friday 8:00 PM ET, including pre-market, regular, post-market and overnight sessions. Weekends are closing hours. ### Example To find the Spot Oracle Price, sort the source prices from lowest to highest and add up their scores in that order. The Spot Oracle Price is the first price at which the running total goes above half of the total score. If the running total lands exactly on half, the price is the average of that source's price and the next one. A source with no fresh price is left out, and the total is recomputed from the sources that remain. The prices below are illustrative. #### Open hours Total score is 9.7, so half is 4.85. | Source | Price | Score | Cumulative score | | ----------- | -----: | :---: | :--------------------: | | Lighter | 110.90 | 0.7 | 0.7 | | Bybit | 111.30 | 1 | 1.7 | | OKX | 111.50 | 1 | 2.7 | | Hyperliquid | 111.70 | 1 | 3.7 | | Binance | 111.90 | 1 | 4.7 | | **Stork** | 112.10 | 2 | 6.7 ← first above half | | Pyth | 112.50 | 3 | 9.7 | The SPCX Spot Oracle Price is **112.10** (Stork). #### Closing hours Total score is 4.7, so half is 2.35. | Source | Price | Score | Cumulative score | | -------------- | -----: | :---: | :--------------------: | | Closing Price | 109.50 | 0.5 | 0.5 | | Internal Price | 110.00 | 0.5 | 1 | | Lighter | 110.40 | 0.7 | 1.7 | | **Bybit** | 110.70 | 1 | 2.7 ← first above half | | Hyperliquid | 111.00 | 1 | 3.7 | | OKX | 111.30 | 1 | 4.7 | The SPCX Spot Oracle Price is **110.70** (Bybit). ### Mark and settlement price * **Mark price**: the Spot Oracle Price is the spot input $S$ to the synthetic forward used by the [Black-76 mark price](/trading/dated-options/mark-price). * **Settlement price**: options settle at 08:00 UTC on the expiry date using a [30-minute TWAP](/trading/dated-options#settlement) of the Spot Oracle Price ending at expiry.
