| | | ## 策略时序 |
| | | |
| | | ### 阶段 1:启动 |
| | | ### 阶段 1:启动与初始化 |
| | | |
| | | ``` |
| | | Spring @PostConstruct |
| | | → GateConfig.builder()...build() |
| | | → GateGridTradeService(config) |
| | | → init(): 查ID → 查账户切持仓 → 清旧条件单 → 设杠杆 |
| | | → init(): |
| | | 1. 查用户ID |
| | | 2. 查账户 → 如需要切持仓模式 |
| | | 3. 清除旧止盈止损条件单 |
| | | 4. 查当前合约所有仓位 → 逐个市价平仓(reduce_only, IOC) |
| | | - 单向持仓: size=相反数平仓 |
| | | - 双向持仓: size=0, close=false, autoSize=LONG/SHORT |
| | | 5. 设杠杆 |
| | | → GateKlineWebSocketClient(config.getWsUrl()) |
| | | → addChannelHandler x3 → init() → connect() |
| | | → onOpen: handlers依次subscribe → sendPing |
| | |
| | | |
| | | ``` |
| | | K线推送 → onKline(closePrice) → state=OPENING |
| | | → GateTradeExecutor.openLong → 市价开多 → onSuccess: longActive=true, 下TP单 |
| | | → GateTradeExecutor.openShort → 市价开空 → onSuccess: shortActive=true, 下TP单 |
| | | → GateTradeExecutor.openLong(qty, onSuccess, null) |
| | | → 市价开多 → onSuccess: longActive=true, placeTakeProfit(多头TP) |
| | | → GateTradeExecutor.openShort(-qty, onSuccess, null) |
| | | → 市价开空 → onSuccess: shortActive=true, placeTakeProfit(空头TP) |
| | | → 双开均完成 → state=ACTIVE |
| | | ``` |
| | | |
| | | ### 阶段 3:止盈触发 → 补仓 |
| | | ### 阶段 3:止盈触发 → 补仓(含重试) |
| | | |
| | | ``` |
| | | 仓位推送: dual_long, size=0 → longActive且无仓位 → tryReopenLong |
| | | → GateTradeExecutor.openLong → 市价补多 → onSuccess: 下新TP单 |
| | | 仓位推送: mode=DUAL_LONG, size=0 → longActive且无仓位 → tryReopenLong() |
| | | ┌─ longReopenFails++ → 超 reopenMaxRetries → STOPPED |
| | | └─ GateTradeExecutor.openLong(qty, |
| | | onSuccess: failCount=0, ACTIVE, 下新TP单, |
| | | onFailure: → 递归调用 tryReopenLong() 再试 |
| | | ) |
| | | |
| | | 仓位推送: dual_short, size=0 → shortActive且无仓位 → tryReopenShort |
| | | → GateTradeExecutor.openShort → 市价补空 → onSuccess: 下新TP单 |
| | | 仓位推送: mode=DUAL_SHORT, size=0 → 同理 tryReopenShort() |
| | | ``` |
| | | |
| | | > 止盈由 Gate 服务端条件单自动执行。只补被平掉的单方向,另一方不受影响。 |
| | | > 补仓失败通过 onFailure 回调递归重试,连续失败超过 `reopenMaxRetries`(默认3次)则停止策略。 |
| | | |
| | | ### 阶段 4:停止 |
| | | |
| | | ``` |
| | | 平仓推送: pnl=+0.6 → cumulativePnl=0.6 ≥ overallTp → state=STOPPED |
| | | 平仓推送: pnl=-8.0 → cumulativePnl=-8.0 ≤ -maxLoss → state=STOPPED |
| | | 补仓连续失败 4 次 → 超过 reopenMaxRetries=3 → state=STOPPED |
| | | ``` |
| | | |
| | | --- |
| | |
| | | | overallTp | 0.5 USDT | 整体止盈 | |
| | | | maxLoss | 7.5 USDT | 最大亏损 | |
| | | | quantity | 1 | 下单张数 | |
| | | | reopenMaxRetries | 3 | 补仓重试次数 | |
| | | | reopenMaxRetries | 3 | 补仓最大重试次数 | |

| | | |
| | | ## GateTradeExecutor |
| | | |
| | | **角色**: 独立线程池执行 REST API 下单,解决 WebSocket 回调线程阻塞问题。 |
| | | **角色**: 独立线程池执行 REST API 下单。采用成功/失败双回调模式支持补仓重试。 |
| | | |
| | | **线程模型**: |
| | | - `ThreadPoolExecutor(1, 1, 60s, LinkedBlockingQueue(64), CallerRunsPolicy)` |
| | | - 单线程保序 + 有界队列防堆积 + CallerRuns背压 |
| | | |
| | | **回调设计**: |
| | | - 每个下单方法接受 `onSuccess` 和 `onFailure` 两个 `Runnable` |
| | | - REST 调用成功 → 执行 `onSuccess`(更新状态、下止盈单、重置失败计数) |
| | | - REST 调用失败 → 执行 `onFailure`(递归重试入口) |
| | | |
| | | | 方法 | 说明 | |
| | | |------|------| |
| | | | `openLong(qty, onSuccess)` | 异步 IOC 市价开多,成功回调 | |
| | | | `openShort(qty, onSuccess)` | 异步 IOC 市价开空 | |
| | | | `openLong(qty, onSuccess, onFailure)` | 异步 IOC 市价开多,双回调 | |
| | | | `openShort(qty, onSuccess, onFailure)` | 异步 IOC 市价开空,双回调 | |
| | | | `placeTakeProfit(trigger, rule, type, auto)` | 异步条件单。已存在则清除旧单重试 | |
| | | | `cancelAllPriceTriggeredOrders()` | 清除所有条件单 | |
| | | | `shutdown()` | 等待10秒,超时强制关闭 | |
| | |
| | | |
| | | **角色**: 策略核心,使用 Gate SDK 管理状态和执行下单。 |
| | | |
| | | **状态**: StrategyState enum + longActive/shortActive boolean |
| | | **状态**: `StrategyState` enum + `longActive`/`shortActive` boolean |
| | | |
| | | **关键常量**(替代字面字符串): |
| | | ```java |
| | | private static final String AUTO_SIZE_LONG = "close_long"; |
| | | private static final String AUTO_SIZE_SHORT = "close_short"; |
| | | private static final String ORDER_TYPE_CLOSE_LONG = "close-long-position"; |
| | | private static final String ORDER_TYPE_CLOSE_SHORT = "close-short-position"; |
| | | ``` |
| | | |
| | | **回调方法**: |
| | | - `onKline(closePrice)`: 缓存价格,WAITING_KLINE状态下首次触发双开 |
| | | - `onPositionUpdate(mode, size, entryPrice)`: size=0且方向活跃 → 补仓 |
| | | - `onPositionUpdate(Position.ModeEnum mode, size, entryPrice)`: `== DUAL_LONG/DUAL_SHORT` 枚举比较,size=0且方向活跃 → 补仓重试 |
| | | - `onPositionClose(side, pnl)`: 累加盈亏,检查停止条件 |
| | | |
| | | **补仓重试逻辑**: |
| | | ``` |
| | | tryReopenLong(): |
| | | 1. longReopenFails++(失败计数递增) |
| | | 2. 超过 reopenMaxRetries → STOPPED |
| | | 3. openLong(qty, |
| | | onSuccess → failCount=0, ACTIVE, 下新TP单, |
| | | onFailure → 递归 tryReopenLong() 重试 |
| | | ) |
| | | ``` |
