### ⚠️ CRITICAL: `contractSize` ≠ 1 张 = 1 个币 (2026-09-04 实战, user 原话 "我只能买 0.95 刀的?")
OKX SWAP 合约的"张" = `contractSize` 个币, **不是 1 个币**:
| 合约 | contractSize | 1 张名义 (按 ~$1000 BTC) |
|---|---|---|
| BTC-USDT-SWAP | 0.01 | 0.01 BTC ≈ $1000 |
| ETH-USDT-SWAP | 0.1 | 0.1 ETH ≈ $400 |
| SOL-USDT-SWAP | 1 | 1 SOL ≈ $200 |
| ZEC-USDT-SWAP | 0.01 | 0.01 ZEC ≈ $9.5 |
| SKHYNIX/SPCX-USDT-SWAP | 0.01 | 0.01 个币 |
**示例** (ZEC @ $955, 1 张 @ 10x):
- 1 张 ZEC = 0.01 × $955 = **$9.56 名义** (不是 $955)
- 10x 杠杆 → 保证金 **$0.96** (不是 $95.6)
**铁律**:
- 下单前先 `ex.load_markets()` + `ex.market(symbol)['contractSize']`
- 计算: `名义 = 张数 × contractSize × price`
- 推送展示 **名义 $**, 不要只说"买 X 张" (用户会误解成买 X 个币)
- 用户说"买 X 张" → agent 应自动换算成 "0.Y 币 = $Z 名义" 二次确认
### Pitfalls (continued)
- **`set_margin_mode` error**: OKX returns `params["lever"] should be between 1 and 125` if margin mode is already set. This is **harmless** — the error message is misleading (mentions `lever` even though you're setting margin mode). Safe to catch and ignore. Full error: `okx setMarginMode() params["lever"] should be between 1 and 125`.
