Model based feeds generate price data by applying mathematical models to various inputs rather than relying solely on direct market quotes. This approach is particularly useful for pricing complex derivatives or assets with low liquidity where reliable spot prices are unavailable. The model calculates a theoretical fair value based on parameters like volatility, interest rates, and time to expiration. This method provides a robust alternative to simple price aggregation.
Data
These feeds utilize a combination of on-chain and off-chain data points as inputs for their calculations. The model processes raw data, such as transaction volumes and implied volatility from options markets, to produce a synthetic price feed. This method provides a robust alternative to simple price aggregation, especially for assets with limited trading pairs. The integrity of the input data is critical for the accuracy of the model.
Pricing
The use of model based feeds is critical for accurate pricing in decentralized derivatives protocols. By providing a reliable, calculated price, these feeds prevent manipulation and ensure fair settlement for options and futures contracts. The model’s output serves as the reference price for margin calculations and liquidation events.
