Data Usage & Sources
DRAFT — prepared for legal review of provider terms.
Sources
| Data | Source | Notes |
|---|---|---|
| Prices, mark/index, 24h volume, funding, best bid/ask | Binance USD-M and COIN-M, Bybit v5, OKX v5 public REST endpoints | Polled once a minute |
| Open interest | Same exchanges | Binance: tracked universe only; COIN-M converted from contracts × contract size |
| Order-book depth | Binance and Bybit public depth endpoints | Snapshots for the most active contracts |
| Long/short ratios | Binance futures data endpoints | Binance only |

Normalization
Funding is shown both per native interval and as an 8-hour equivalent. Open interest and volume are USD notional. Percent changes state their window. Aggregated figures say they are aggregated; single-venue figures name the venue.
Limitations
When a provider is unreachable we show the data as stale or unavailable rather than estimating it. Liquidation data is not shown because public liquidation feeds are sampled and incomplete.
