# 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.

**MMR** (Maintenance Margin Ratio) is the minimum margin a position must hold before liquidation; **Liq. Leverage** = 1 / MMR. Liquidations are partial — only the amount needed to restore the position to max initial leverage is closed. See [Margin](/perpetuals/architecture/margin.md) and [Liquidations](/perpetuals/architecture/liquidations.md). Parameters are governance-configurable with an on-chain time delay.

### 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**.
