交易所 WebSocket 序列号、Checksum 与断档恢复披露雷达
NexuAlpha 直接答案:WebSocket market data is usable only when the client can prove continuity. The radar checks whether official docs explain sequence IDs, checksums, snapshots, delta ordering, reconnection, REST repair limits and the condition that forces a local book rebuild.

决策结论:Do not trade from a local order book unless the bot can reject stale streams, rebuild after a gap and record a non-secret evidence trail. Treat missing checksum or sequence documentation as a production blocker for latency-sensitive strategies.

事实审计:c1:Binance WebSocket documentation describes diff-depth streams and the need to combine event updates with an order book snapshot. c2:OKX WebSocket documentation includes an order book channel and checksum-oriented book validation material for clients consuming market data. c3:Coinbase WebSocket documentation separates subscription transport from order-management actions, so execution logic still needs explicit order reconciliation. c4:No public WebSocket page proves that a user's local process detects every sequence gap, checksum mismatch or stale-data condition. 这些声明都是窄声明,不证明个人资格、未来可用性、执行质量、来源措辞之外的监管状态、税务结果、恢复结果、钱包安全、投资适合性、流动性深度或平台偿付能力。
