加密交易 API 二进制协议与 JSON 回退披露雷达
本文正文暫以英文原文展示，翻譯版本需完成來源複核後再發布。
已验证事实边界
1. OKX's API changelog describes SBE services alongside existing REST and JSON WebSocket APIs. 2. Binance's spot API documentation changelog includes FIX order-entry and FIX drop-copy changes. 3. Coinbase's Advanced Trade WebSocket documentation describes WebSocket market-data behavior and channel usage. 4. Bybit's V5 integration guidance documents request timing, authentication and integration constraints for API users. 5. Across these sources, protocol choice affects parsing, authentication, sequencing, reconnect and fallback evidence. 6. These sources do not prove that a private trading system reconciles all fills, handles every disconnect, or is protected against future schema and policy changes.

文章表格：可橫向滑動，或聚焦表格區域後使用方向鍵。
| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Protocol type | SBE, FIX, JSON WebSocket and REST imply different parser and failure modes | record protocol and endpoint class for each order path | venue-specific feature parity |
| Schema version | binary and FIX integrations can fail silently when schema assumptions drift | pin schema files or changelog evidence in release notes | future field additions and deprecations |
| Replay rule | order and market-data streams need reconnect, gap and replay evidence | define replay and REST backfill before going live | outage behavior and incomplete historical recovery |
| Fallback endpoint | a fallback is useful only if it preserves order and position truth | test JSON or REST fallback against the primary channel | rate limits and partial outage conditions |
| Stop condition | automation should pause when channel authority cannot be reconciled | stop trading if fills, cancels, positions or sequence state disagree | private venue incident timelines remain unknown |

控制说明
1. Protocol type
这一项要求读者把公开来源翻译成操作规则。这里的含义是：SBE, FIX, JSON WebSocket and REST imply different parser and failure modes。可执行动作是：record protocol and endpoint class for each order path。仍然未知的是：venue-specific feature parity。因此本文不会把未知部分包装成收益承诺、牌照承诺、审批保证、安全保证、恢复保证、平台排名或价格暗示。
2. Schema version
这里的含义是：binary and FIX integrations can fail silently when schema assumptions drift。可执行动作是：pin schema files or changelog evidence in release notes。仍然未知的是：future field additions and deprecations。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
3. Replay rule
这里的含义是：order and market-data streams need reconnect, gap and replay evidence。可执行动作是：define replay and REST backfill before going live。仍然未知的是：outage behavior and incomplete historical recovery。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
4. Fallback endpoint
这里的含义是：a fallback is useful only if it preserves order and position truth。可执行动作是：test JSON or REST fallback against the primary channel。仍然未知的是：rate limits and partial outage conditions。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
5. Stop condition
这里的含义是：automation should pause when channel authority cannot be reconciled。可执行动作是：stop trading if fills, cancels, positions or sequence state disagree。仍然未知的是：private venue incident timelines remain unknown。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
仍需明确的未知项
- venue-specific feature parity
- future field additions and deprecations
- outage behavior and incomplete historical recovery
- rate limits and partial outage conditions
- private venue incident timelines remain unknown
实用结论
NexuAlpha radar signal 是：交易所正在把 high-performance binary/FIX channels 与 JSON/REST fallback paths 分开，披露质量与原始延迟同样重要。OKX 记录新的 SBE order-entry 与 private-data services，Binance developer changelog 提到 FIX order-entry 与 drop-copy changes，Coinbase 记录 Advanced Trade WebSocket behavior，Bybit 记录 V5 integration rules。实用决策是在 trading system 把任何单一 API channel 视为权威之前，要求 protocol type、schema version、authentication path、sequence/replay rule、fallback endpoint 与 incident rollback。 本文停在证据边界内，帮助读者决定下一步核验什么，而不是把公开文档改写成私人账户、钱包、API key、池子路径、稳定币余额、代币化资产或政策框架在任何未来条件下都能成功的承诺。
