# Price data and charts

Deryve prioritizes Lighter’s mark price for tradable markets. This is the price used for position valuation and settlement calculations.

### Price sources

| Source label | Meaning                       | Trading availability                |
| ------------ | ----------------------------- | ----------------------------------- |
| `lighter`    | Live mark price from Lighter  | Available when the market is active |
| `coingecko`  | Informational crypto fallback | Not sufficient for execution        |

The 24-hour change, high, and low derive from recent hourly observations. CoinGecko can supplement informational crypto display when Lighter data is unavailable.

### Funding

Funding transfers value between longs and shorts every hour.

* **Positive funding:** longs pay shorts.
* **Negative funding:** shorts pay longs.
* **Displayed rate:** review each market’s current rate before holding a position.

Funding is a carrying cost or credit. It can materially affect longer-held leveraged positions.

### Chart selection

Deryve uses the best available chart source for each market.

1. **On-chain pool chart** for verified Robinhood Chain liquidity pools.
2. **Exchange chart** for assets with a reliable listed-market symbol.
3. **Synthetic OHLCV chart** for markets without an exchange chart.

Synthetic candles derive from Lighter’s hourly price series. They support 1H, 4H, and 1D aggregation. Their volume may be unavailable.

### Interpreting synthetic candles

Synthetic candles are useful for trend, range, and indicator analysis. They are not a replacement for complete order-flow data. Confirm liquidity and mark-price availability before execution.
