Real estate oracle

The real estate markets are NYC, USA, Austin, Atlanta, Boston, and MiamiBeach (market IDs 0 through 5). They use a daily oracle sourced from Parcl Labs.

How it works

Source. Parcl Labs publishes a daily real estate price index per market, computed from a rolling window of transaction data.
Cadence. One on-chain update per market per day.
On chain. Each accepted daily update becomes the market's active oracle value.

Between updates, the chain holds the most recent published value. The underlying transaction data does not exist at a higher frequency.

What goes on chain

Field	Meaning
`oracle_price`	The published index value in USD, scaled to `PRICE_EXPO = -8`
`last_oracle_timestamp`	Wall-clock at submission
`oracle_valid_until`	The time after which the chain marks the current value as expired
`oracle_status`	`Active` while `now < valid_until`, `Stale` after that, or `Halted` when the update is unavailable

What you'll see in the UI

Index price: the latest oracle value. Doesn't change intraday.
A countdown next to the Index price showing when the current value expires.

The Index price is intentionally flat between updates. That's correct behavior. The housing market itself doesn't tick every second.

Mark price and triggers

For real estate liquidations and TP/SL triggers, the chain uses oracle_price directly. See mark price for the full routing.

A stop fires when a daily oracle update crosses its threshold. Order-book movement between oracle updates does not trigger it.

Halted updates

If oracle_status is Halted, do not increase exposure.
