/**
 * 网格交易策略引擎 — 多空对冲网格。
 *
 * <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>完整生命周期</h3>
 * <pre>
 *   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>
 *
 * <h3>仓位线动态调整</h3>
 * <pre>
 *   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。
