# Position model

> The normalized fields Retina uses for every position (source, wallet, chain, protocol, type, asset class, maturity, APY) and how APY is derived.

Every position from every source is normalized into 1 internal shape. The [Positions Explorer](/pages/positions) shows this shape directly.

## Fields

| Field         | Description                                                                                                                                                    |

## How APY is derived

Retina reads APY in this order:

1. **Protocol-reported APY**, when the provider returns one. This covers Pendle, Hyperliquid staking, and many EVM vaults.
2. **DeFiLlama fallback** for pools without a direct report.
3. **Live funding rate** for perp positions.

If none of those returns a number, the APY field is empty and you can fill it in with a **Manual APY** override on the Dashboard's Yield Table.

## Estimated daily income

The Dashboard's `Estimated / Day` column applies the APY to the current position value and divides to a per-day number. This assumes APY is constant over the day. Real yields fluctuate, so treat the daily number as an estimate.
