# 24/5 Equity Markets

Equity-referenced perpetuals track stock and equity index prices via oracle feeds sourced from U.S. exchange pricing. Because the underlying equity markets are not open around the clock, these perpetuals follow the trading session schedule of the relevant exchange.

### Notes

* Equity perpetuals are priced via [Pyth Network](https://pyth.network/) oracle feeds that reflect real-time U.S. equity exchange pricing.
* During off-hours when the oracle feed is stale, positions are protected from unfair liquidations by Aftermath's mark price mechanism — the mark price can never deviate more than **5% from the oracle index price**.
