Xstocks price feed aggregation question

Hi there, I’m integrating a short-duration (like 30s) binary trading system for stocks. It looks like Pyth Core only supports regular market hours. Does the Pro service cover pre-market, post-market, and overnight sessions?

Also, could you point me to documentation on how xStocks price aggregation works? I assume it pulls from multiple venues (DEXs and CEXs), and I’d like to verify it’s resistant to manipulation given that liquidity for xStocks is likely thin.

Yes, about 150 equities have 24/5 data as of today

Regarding xstocks, aggregation is similar as for all the other feeds, follow this model: How Pyth Pro Works | Pyth Developer Hub
And indeed sourced from multiple venues.
