 /**
- * Gate 网格交易服务 — 策略核心。
+ * 网格交易策略引擎 — 多空对冲网格。
  *
- * <h3>策略</h3>
- * 多空双开基底 → 生成价格网格队列 → K线触达网格线 → 开仓+设止盈 → 队列动态转移。
- * 每根 K 线更新 {@code unrealizedPnl}(浮动盈亏),平仓后累加到 {@code cumulativePnl}(已实现盈亏)。
+ * <h3>策略原理</h3>
+ * 以空仓基底入场价(shortBaseEntryPrice)为价格基准,向上/向下各生成一个价格网格队列。
+ * 价格触发网格层级时挂条件单,成交后自动挂止盈单。每笔止盈盈利 = step - minTick。
  *
- * <h3>未实现盈亏公式(正向合约)</h3>
+ * <h3>完整生命周期</h3>
  * <pre>
- *   多仓: 持仓量 × 合约乘数 × (计价价格 − 开仓均价)
- *   空仓: 持仓量 × 合约乘数 × (开仓均价 − 计价价格)
+ *   init() → startGrid() → WAITING_KLINE
+ *     ↓
+ *   onKline(首根K线) → OPENING → 异步市价双开基底(开多+开空)
+ *     ↓
+ *   onPositionUpdate() → 基底成交 → baseLongOpened && baseShortOpened
+ *     ↓
+ *   tryGenerateQueues()
+ *     ├── generateShortQueue()   ← 空仓价格队列(降序,从 shortBaseEntryPrice-step 向下)
+ *     ├── generateLongQueue()    ← 多仓价格队列(升序,从 shortBaseEntryPrice+step 向上)
+ *     ├── updateGridElements()   ← 构建 GridElement 列表 + TraderParam + 全局索引
+ *     ├── 挂基座止盈单(ID=0 的 long/short takeProfit)
+ *     └── 挂初始条件单(up=-1 多单, down=1 空单)
+ *     ↓
+ *   state = ACTIVE(每根K线反复执行以下循环)
+ *     ↓
+ *   onKline() → processLongGrid() + processShortGrid()
+ *     ├── 匹配队列元素 → 队列补偿 → 保证金检查
+ *     ├── 首元素方向:挂条件开仓单 → 订单ID + GridElement状态同步
+ *     └── 反向守卫:在 downGrid 位置挂对向单(价格区间+trigger方向校验)
+ *     ↓
+ *   onOrderUpdate()  ← futures.orders / futures.autoorders 推送
+ *     ├── 匹配止盈单ID → 清空止盈状态(已成交)
+ *     └── 匹配挂单ID → 挂止盈条件单 → 止盈ID + GridElement状态同步
+ *     ↓
+ *   onPositionClose() → cumulativePnl 累加
+ *     ├──  ≥ overallTp → STOPPED
+ *     └──  ≤ -maxLoss → STOPPED
  * </pre>
- * 计价价格支持切换:{@link GateConfig.PnLPriceMode#LAST_PRICE 最新成交价} 或
- * {@link GateConfig.PnLPriceMode#MARK_PRICE 标记价格}(通过 {@link #setMarkPrice(BigDecimal)} 注入)。
- * 入场价和持仓量由 {@link #onPositionUpdate(String, Position.ModeEnum, BigDecimal, BigDecimal)} 实时更新。
  *
- * <h3>状态机</h3>
+ * <h3>仓位线动态调整</h3>
  * <pre>
- *   WAITING_KLINE → (首K线) → 异步双开基底
- *
- *   仓位推送(dual_long/dual_short) → 基底成交 → 记录入场价 → 双基底都成交 → 生成队列 → ACTIVE
- *
- *   ACTIVE:
- *     ├─ 每根K线 → 更新 unrealizedPnl + processShortGrid + processLongGrid
- *     │    ├─ 当前价 &lt; 空仓队列元素 → 匹配 → 开空 + 队列元素转移到多仓队列
- *     │    └─ 当前价 &gt; 多仓队列元素 → 匹配 → 开多 + 队列元素转移到空仓队列
- *     ├─ 仓位推送(非基底) → 设止盈条件单 entry × (1±gridRate)
- *     ├─ 保证金≥初始本金 marginRatioLimit → 跳过开仓,队列照常更新
- *     └─ cumulativePnl ≥ overallTp 或 ≤ -maxLoss → STOPPED
+ *   onPositionUpdate() 中仓位均价变化后:
+ *     longEntryPrice ↑ → 取消 高于 longEntryPrice 的空仓挂单(避免逆势空单)
+ *     shortEntryPrice ↓ → 取消 低于 shortEntryPrice 的多仓挂单(避免逆势多单)
  * </pre>
+ *
+ * <h3>关键公式</h3>
+ * <pre>
+ *   step  = shortBaseEntryPrice × gridRate                      ← 网格绝对步长
+ *   minTick = 10^(-priceScale)                                  ← 交易所最小价格单位
+ *   多止盈 = gridPrice + (step - minTick)                       ← 多仓止盈价
+ *   空止盈 = gridPrice - (step - minTick)                       ← 空仓止盈价
+ *   单笔盈利 = (step - minTick) × contractMultiplier × quantity  ← USDT
+ * </pre>
+ *
+ * <h3>线程模型</h3>
+ * 所有 WS 回调(onKline/onPositionUpdate/onOrderUpdate 等)在 WS 回调线程中串行执行。
+ * 下单/撤单操作提交到 GateTradeExecutor 的单线程池异步执行,避免阻塞 WS 线程。
+ * stopGrid() 会将 state 设为 STOPPED,后续所有 WS 回调直接返回不再处理。
