Bybit WebSocket 批量下单改单撤单时间戳准备清单
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. Bybit's V5 changelog lists WebSocket order-entry updates for batch create, amend and cancel workflows. 2. Bybit websocket trade guidance rejects requests outside the documented timestamp and receive-window condition. 3. Bybit rate-limit documentation separates API limits by endpoint, product and upgrade status. 4. Bybit amend-order documentation requires orderId or orderLinkId and treats amend acknowledgement as asynchronous. 5. A changelog entry does not prove a user's key, account mode, product category, symbol or bot architecture is ready for batch trading. 6. The safe readiness record separates clock validity, request envelope, batch item mapping, websocket state confirmation, endpoint limit and rollback action.

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 |
|---|---|---|---|
| Changelog scope | a listed WebSocket update is a product-surface signal, not an account-specific permission | record the exact changelog item and affected route before rollout | whether the user's product category is covered by the update |
| Clock validation | timestamp and receive-window checks can reject otherwise valid order messages | monitor local clock drift and server-time tolerance before trading | what happens after network delay exceeds the receive window |
| Batch item mapping | a batch request can create multiple independent item outcomes | persist item-level request and response records rather than only the batch envelope | which item should be retried when only one amend fails |
| Endpoint budget | rate limits can differ by endpoint, product and account upgrade state | reserve separate budgets for create, amend, cancel and status lookup | whether a burst from another bot shares the same bucket |
| State confirmation | accepted requests still need final state from websocket or query routes | block downstream replacement orders until final state is observed | how to handle reconnect gaps between acknowledgement and final state |
| Rollback action | batch order entry needs an explicit stop rule before the first live call | define disable switch, cancel policy and reconciliation owner | whether cancel-all is appropriate or too broad for a partial failure |

控制说明
1. Changelog scope
这一项要求读者先把公开来源翻译成操作规则。这里的含义是：a listed WebSocket update is a product-surface signal, not an account-specific permission。可执行动作是：record the exact changelog item and affected route before rollout。仍然未知的是：whether the user's product category is covered by the update。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、恢复保证、结算保证、可用性保证、价格暗示或平台排名。
2. Clock validation
这里的含义是：timestamp and receive-window checks can reject otherwise valid order messages。可执行动作是：monitor local clock drift and server-time tolerance before trading。仍然未知的是：what happens after network delay exceeds the receive window。
操作测试也必须很窄。这就是本节保留边界的原因。
3. Batch item mapping
这里的含义是：a batch request can create multiple independent item outcomes。可执行动作是：persist item-level request and response records rather than only the batch envelope。仍然未知的是：which item should be retried when only one amend fails。
操作测试也必须很窄。这就是本节保留边界的原因。
4. Endpoint budget
这里的含义是：rate limits can differ by endpoint, product and account upgrade state。可执行动作是：reserve separate budgets for create, amend, cancel and status lookup。仍然未知的是：whether a burst from another bot shares the same bucket。
操作测试也必须很窄。这就是本节保留边界的原因。
5. State confirmation
这里的含义是：accepted requests still need final state from websocket or query routes。可执行动作是：block downstream replacement orders until final state is observed。仍然未知的是：how to handle reconnect gaps between acknowledgement and final state。
操作测试也必须很窄。这就是本节保留边界的原因。
6. Rollback action
这里的含义是：batch order entry needs an explicit stop rule before the first live call。可执行动作是：define disable switch, cancel policy and reconciliation owner。仍然未知的是：whether cancel-all is appropriate or too broad for a partial failure。
操作测试也必须很窄。这就是本节保留边界的原因。
仍需明确的未知项
- whether the user's product category is covered by the update
- what happens after network delay exceeds the receive window
- which item should be retried when only one amend fails
- whether a burst from another bot shares the same bucket
- how to handle reconnect gaps between acknowledgement and final state
- whether cancel-all is appropriate or too broad for a partial failure
实用结论
Bybit V5 order-entry 材料应被理解为实施准备清单，而不是每个机器人都能安全批量交易的保证。官方 changelog 列出 WebSocket order-entry batch create、amend 与 cancel 更新，WebSocket trade guide 说明 timestamp 与 receive-window 校验，rate-limit 页面则按产品和端点区分限制。实用结论是：在生产启用 batch amend 或 cancel 前，先要求本地时钟检查、request envelope 记录、batch-item result map、websocket state confirmation 与端点级 rate budget。 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、回调、政策框架、结算路径或流动性头寸在任何未来条件下都能成功的承诺。
