L-02 Low Pyth Confidence Intervals Are Not Considered Best Practices Pending
Description
Pyth prices offer a confidence interval range for every price, this is because the exact price of an asset cannot be given due to difference across exchanges and reporting sources, especially during times of volatility. Pyth recommends that the confidence interval be used in two ways, which could be adapted to the use-case for the USD0 Cauldron system:
- Opt to not use the Pyth price if the confidence range becomes too wide, as this is an indication of uncertain pricing which may lead to profitable arbitrage opportunities.
- Apply the confidence range returned from Pyth as a spread, moving in the direction that would be disadvantageous for traders.
Recommendation
Consider adopting one or both of these use-cases for the pyth confidence interval to provide protection for uncertain pricing results.
