Mark Price

The mark price of each instrument is computed as the price-impact mid-market price on the instrument's orderbook within the protocol. The only orders that are counted for the mid-market price are valid orders able to be filled by another order.

The price impact is variable per market, and currently is set to 0 in every market to ensure the mark price is representative even in a period of launch liquidity.

If the mark price deviates from more than 10% in either direction from the index price, the index price -+10% is used instead of the mark. For example, if the mid-market price is 0.8, and the index is 1.0, then the mark price will be reported as 0.9.
