Kraken 与 Coinbase WebSocket 心跳、重连与订单状态控制对比
已验证事实边界
1. Kraken documents WebSocket v2 as a separate API surface for public and private channels. 2. Kraken WebSocket v2 trading endpoints include add_order, so trading actions and market-data subscriptions should be reconciled separately. 3. Kraken REST documentation provides a WebSockets token endpoint for authenticated WebSocket access. 4. Coinbase Exchange WebSocket documentation describes feed connection behavior and channel subscriptions for exchange data. 5. Coinbase channel documentation is a source for channel-specific payload expectations and sequence handling. 6. A safe comparison separates connection liveness, message order, reconnect behavior, authenticated scope and final order-state reconciliation.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Liveness signal | heartbeat or connection behavior proves only that a session is alive enough to receive messages | log heartbeat, close reason and reconnect timestamp without secrets | whether the library masks missed heartbeat events |
| Message continuity | sequence handling and channel ordering determine whether a local book or order view is stale | treat any detected gap as a reconciliation trigger | whether dropped messages occurred before local detection |
| Authenticated scope | private feeds require token or authenticated setup separate from public market data | store only token request metadata and channel names | whether token expiration differs across worker processes |
| Trading action boundary | WebSocket order placement is not the same as a final order-state record | query final REST or private-feed state after lost responses | whether a partial fill changed the order meaning before reconnect |
| Reconnect path | a reconnect can replay, skip or reorder locally observed state depending on client behavior | reset subscriptions and compare a fresh snapshot before resuming automation | whether stale local strategy state survives the reconnect |
| Evidence hygiene | debug logs can expose channel names, order ids and account metadata | keep source URL, channel, non-secret order id, event and final state only | whether screenshots reveal balances or private strategy timing |

控制说明
1. Liveness signal
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:heartbeat or connection behavior proves only that a session is alive enough to receive messages。可执行动作是:log heartbeat, close reason and reconnect timestamp without secrets。仍然未知的是:whether the library masks missed heartbeat events。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. Message continuity
这里的含义是:sequence handling and channel ordering determine whether a local book or order view is stale。可执行动作是:treat any detected gap as a reconciliation trigger。仍然未知的是:whether dropped messages occurred before local detection。
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. Authenticated scope
这里的含义是:private feeds require token or authenticated setup separate from public market data。可执行动作是:store only token request metadata and channel names。仍然未知的是:whether token expiration differs across worker processes。
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. Trading action boundary
这里的含义是:WebSocket order placement is not the same as a final order-state record。可执行动作是:query final REST or private-feed state after lost responses。仍然未知的是:whether a partial fill changed the order meaning before reconnect。
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. Reconnect path
这里的含义是:a reconnect can replay, skip or reorder locally observed state depending on client behavior。可执行动作是:reset subscriptions and compare a fresh snapshot before resuming automation。仍然未知的是:whether stale local strategy state survives the reconnect。
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。
6. Evidence hygiene
这里的含义是:debug logs can expose channel names, order ids and account metadata。可执行动作是:keep source URL, channel, non-secret order id, event and final state only。仍然未知的是:whether screenshots reveal balances or private strategy timing。
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
- whether the library masks missed heartbeat events
- whether dropped messages occurred before local detection
- whether token expiration differs across worker processes
- whether a partial fill changed the order meaning before reconnect
- whether stale local strategy state survives the reconnect
- whether screenshots reveal balances or private strategy timing
实用结论
Kraken 与 Coinbase 都提供可用于交易自动化的 WebSocket feed,但任何一个 feed 都不应被当成完整订单风险记录。Kraken WebSocket v2 文档区分 market-data channels、trading endpoints 和 authenticated-token setup;Coinbase Exchange WebSocket 文档则描述 exchange feed 的 channel subscriptions、sequence handling 与 connection behavior。实用对比是:机器人在断线后依赖任一平台前,先证明 heartbeat 或 liveness 行为、sequence continuity、reconnect path、authenticated channel scope、REST reconciliation 与不含秘密的日志记录。 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。
