# Price Indices

Notional uses Hyperliquid market data as the primary price source for the initial deployment.

Perp margin, account monitoring, funding, and liquidation calculations use Hyperliquid mark prices.

Display spot prices use Hyperliquid spot/all-mids, Binance, and Pyth when those feeds are
configured and fresh. USDC is always priced at \$1.00.

Spot collateral margining uses a separate collateral-risk price path. Assets configured to use
spot-only pricing use the Hyperliquid spot mark. Other collateral uses the median of the Hyperliquid
spot mark, perp mark times the USDT/USDC quote oracle, and perp oracle times the USDT/USDC quote
oracle.

For aggregated display prices, Notional records confidence with each resolved price:

|                             Case | Resolution    |
| -------------------------------: | ------------- |
|                  3 fresh sources | median        |
| 2 fresh sources within threshold | average       |
|                   1 fresh source | single source |

Default settings:

| Parameter            |     Value |
