# Oracle & Fixing

### Price feed from Pyth <a href="#price-feed-from-pyth" id="price-feed-from-pyth"></a>

* SuperVol uses [Pyth](https://pyth.network/price-feeds), a pull-based oracle for crypto market data, for the fair calculation of its options.
* Pyth Price Feeds are used for the **Start Price** and **End Price** of each rounds, thus providing both a decentralised and accountable standard to determine user's trade results.
* From July 2025, SuperVol is powered by **Pyth Lazer** - providing real time price updates for super fast trading.&#x20;

{% hint style="info" %}
Display-wise, SuperVol uses chart data from TradingView charts (ex. [BTCUSD](https://www.tradingview.com/symbols/BTCUSD/))&#x20;

However, actual fixing and settlement is made in Pyth price feeds. We advise that users only view charts as a reference.

### Round Fixing & Settlement

{% tabs %}
{% tab title="1 Hour Option" %}
Due to various complexities in round fixing (including blockchain latency, market fluctuations, smart contract risk), orders with less than 1 minute left before expiry have a high risk of failure. It is recommended that users place orders with enough time remaining.

* The price of each coin/token at 00 minutes @ every hour will be used for the fixings of SuperVol's 1 Hour options.
* More precisely, SuperVol listens to the **Pyth price of HH:00:00** at HH:00:10 every hour.
* By structure, the End Price of Round 'N' will be used for the Start Price of Round 'N+1'. Failure in Pyth price retrieval leads to an error in both ending one round and starting a new one.
* Due to various reasons (i.e. delay/shutdown of Pyth, Ethereum or L2 network), SuperVol may fail to retrieve fixing prices.
  * For example, if SuperVol fails to fetch the End Price for Round 'N':
    1. SuperVol will retry every 2 minutes (ex. HH:02:10 / HH:04:10/ ...)
    2. Until Round 'N' is fixed, the opening of **Round 'N+1'** will be delayed (No Start Price).
       * If the issue persists for 60 minutes, **Round 'N+1'** will be cancelled.
    3. Afterwards, SuperVol will search the Start Price for **Round 'N+2'**
    4. Trading will be functional from **Round 'N+2'**
* Regardless of the operation of other rounds, SuperVol will attempt fixing of Round 'N' for a maximum of 24 hours (=Max. 720 attempts)
  * If fixing fails even after 24 hours, SuperVol will use Binance spot price of asset for End Price of **Round 'N'**
    {% endtab %}

{% tab title="1 Minute Option" %}
The price of each coin/token at 00 seconds @ every minute will be used for the fixings of SuperVol's 1 Minute options.

* More precisely, SuperVol listens to the **Pyth price of HH:MM:00** every minute.
* Due to various reasons (i.e. delay/shutdown of Pyth, Ethereum or L2 network), SuperVol may fail to retrieve fixing prices.
* Regardless of the operation of other rounds, SuperVol will attempt fixing of Round 'N' for a maximum of 24 hours (=Max. 720 attempts)
  * If fixing fails even after 24 hours, SuperVol will use Binance spot price of asset for End Price of **Round 'N'**
