+# OKX 永续合约规格速查
+
+常用交易对的合约面值和最小下单量。用于跟单方案的仓位计算。
+
+## 查询方法
+```python
+import requests
+proxies = {"http": "http://127.0.0.1:7890", "https": "http://127.0.0.1:7890"}
+url = f"https://www.okx.com/api/v5/public/instruments?instType=SWAP&instId={sym}"
+r = requests.get(url, proxies=proxies, timeout=10)
+inst = r.json()['data'][0]
+# ctVal = 每张合约面值(币), minSz = 最小下单量(张), lotSz = 步长(张)
+```
+
+## 常用交易对 (2026-07 更新)
+
+| 币种 | instId | ctVal | minSz | 1张≈USDT | 说明 |
+|------|--------|-------|-------|----------|------|
+| ETH | ETH-USDT-SWAP | 0.1 ETH | 0.01 | ~170 | 麻吉大哥主做 |
+| BTC | BTC-USDT-SWAP | 0.01 BTC | 0.01 | ~1,000 | |
+| SOL | SOL-USDT-SWAP | 1 SOL | 0.1 | ~80 | 狙击手做空 |
+| MU | MU-USDT-SWAP | 1 MU | 0.01 | ~970 | 熬鹰资本 |
+| SKHYNIX | SKHYNIX-USDT-SWAP | 1 SKHYNIX | 0.001 | ~1,420 | 熬鹰资本 |
+| SNDK | SNDK-USDT-SWAP | 1 SNDK | 0.001 | ~1,740 | 熬鹰资本 |

+| MSTR | MSTR-USDT-SWAP | 1 MSTR | 0.01 | ~100 | 熬鹰资本(已平仓) |
+
+## 仓位计算公式
+
+```
+名义值 = 张数 × ctVal × 当前价
+保证金 = 名义值 / 杠杆
+最小保证金 = minSz × ctVal × 当前价 / 杠杆
+```
+
+### 示例：ETH 25x
+- 1张 = 0.1 ETH × $1,700 = $170 名义值
+- 保证金 = $170 / 25 = $6.8
+- 用户可用 $24 → 最多开 3 张 (0.3 ETH, 保证金 $20.4)
+
+### 示例：MU 4x
+- 最小 0.01张 = 0.01 MU × $970 = $9.7 名义值
+- 保证金 = $9.7 / 4 = $2.4
+- 用户可用 $24 → 最多开 0.1张 (10 MU, 保证金 $242) — 超出！
+- 建议 0.01-0.02张 (保证金 $2.4-$4.8)
