### Market Operation

The IVX market acts as the counterparty for all users engaging with the IVX protocol. When a user seeks to purchase an option at a specific strike price, the AMM automatically accepts the trade, thereby exposing itself to a corresponding shot option contract of the same asset on that same strike price. If a user wishes to close the purchased option, the AMM's exposure as a seller will be offset, leading the AMM to exercise the option following the American options methodology.

Every day at 8:00 AM UTC, the IVX market generates option contracts for supported assets with incorporated volatility sources, initiating the trading session and enabling traders to write or purchase option positions that expire at 8:00 AM UTC the following day. 

Throughout the 24 hours trading period, (excluding 30 minutes before expiry when trading will be ceased), traders can enter or exit from any position based on a pre-generated list of strike price specific to each asset.

### Strike price list

IVX Strike price list will be align with the same strike price list as Deribit, aggregating three strike prices per asset closer to ATM: \[OTM , ATM , ITM]

Strike prices will roll out automatically as live price moves below OTM strike or moves above ITM strike, otherwise, the list of strike prices will remain unchanged.
