# markets

OCX lists three families of underlyings — each with a spot book, a perpetual, and one or more quarterly futures. Margin nets across all products within a family.

## BTC (digital gold)

| Market                           | Type                  |
| -------------------------------- | --------------------- |
| `BTC-USDC-SPOT`                  | Spot                  |
| `BTC-PERP`                       | Perpetual             |
| `BTC-USDC-2026-06-26`            | Quarterly future (F1) |
| `BTC-USDC-2026-09-25`            | Quarterly future (F2) |
| `BTC-<expiry>-<strike>-C` / `-P` | European options      |

## XAU (gold via XAUT)

| Market                 | Type                     |
| ---------------------- | ------------------------ |
| `XAUT-USDC-SPOT`       | Spot (Tether Gold token) |
| `XAUT-USDC-PERP`       | Perpetual                |
| `XAUT-USDC-2026-06-26` | Quarterly future         |

## WTI (crude oil)

| Market                   | Type                  |
| ------------------------ | --------------------- |
| `WTIOIL-USDC-SPOT`       | Spot                  |
| `WTIOIL-PERP`            | Perpetual             |
| `WTIOIL-USDC-2026-06-26` | Quarterly future (F1) |
| `WTIOIL-USDC-2026-07-31` | Quarterly future (F2) |

## Cross-product margin groups

Markets that share an underlying are cross-margined automatically. A long `BTC-PERP` is offset by a short `BTC-USDC-2026-06-26` in the same account — you pay margin only on the residual exposure.

Correlation credits also apply *across* underlyings in the same asset class:

| Asset class           | Correlation credit |
| --------------------- | ------------------ |
| Crypto (BTC family)   | 50%                |
| Precious metals (XAU) | category-specific  |
| Energy (WTI)          | 40%                |
