Index Price
The Index Price is the real-time spot price of the underlying asset, aggregated via the Variational Oracle.
The Index Price acts as the objective benchmark for the asset’s fair market value.
Mark Price
The Mark Price is the calculated fair value for the perpetual contract, derived from the Index Price plus additional data including funding rates and the OLP risk profile. The Mark Price is used for UPnL, Margin calculations, and liquidations.
The Mark Price is the asset price you track using the Omni trading charts.
Quoted Price
The Quoted Price is the actual price at which you can buy or sell an asset. The Quoted Price represents the price the OLP is willing to accept for your specific trade size at that exact moment.
All trades (Market, Limit, and Trigger) are ultimately executed at a Quoted Price.

To help visualize how these prices interact across Omni, see the table below:
Price | Source | Indication |
Index Price | Variational Oracle | The true, universal asset value |
Mark Price | Internal calculation | The value of the perpetual contract |
Quoted Price | OLP | The price at which you can currently trade |
