/**
 * 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)
 * </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>
 * <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 + 以多仓队列首元素为种子生成新元素加入多仓队列
 *     │    └─ 当前价 &gt; 多仓队列元素 → 匹配 → 开多 + 以空仓队列首元素为种子生成新元素加入空仓队列
 *     ├─ 仓位推送(非基底) → 设止盈条件单 entry × (1±gridRate)，使用 plan-close-*-position
 *     ├─ 保证金≥初始本金 marginRatioLimit → 跳过开仓，队列照常更新
 *     ├─ 额外反向开仓：触发价夹在多/空持仓均价之间且多持仓均价&gt;空持仓均价时，额外反向开仓一次
 *     └─ cumulativePnl ≥ overallTp 或 ≤ -maxLoss → STOPPED
 *   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>队列转移规则</h3>
 * 触发后不再简单复制 matched 元素到对方队列，而是以对方队列首元素为种子，生成新元素：
 * <ul>
 *   <li>空仓队列触发 → 多仓队列新增：以多仓队列首元素（最小价）为基准，生成递减元素</li>
 *   <li>多仓队列触发 → 空仓队列新增：以空仓队列首元素（最高价）为基准，生成递增元素</li>
 * </ul>
 * <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>贴近持仓均价过滤</h3>
 * 转移生成新元素时，若新元素与对应方向持仓均价的差距小于 gridRate，则跳过该元素，
 * 避免在持仓成本附近生成无效网格线。
 * <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>额外反向开仓条件</h3>
 * 当触发价在空仓均价和回撤后的多仓均价之间（即多&gt;空且价格夹在中间），额外反向开仓一次：
 * <ul>
 *   <li>空仓队列触发 → 额外开多：需满足 shortEntryPrice &lt; currentPrice &lt; longEntryPrice × (1 − gridRate)</li>
 *   <li>多仓队列触发 → 额外开空：需满足 shortEntryPrice × (1 + gridRate) &lt; currentPrice &lt; longEntryPrice</li>
 * </ul>
 *
 * <h3>止盈条件单</h3>
 * 使用 Gate API 的 plan-close-long-position / plan-close-short-position（仓位计划止盈止损），
 * 支持指定张数部分平仓。每次网格触发开仓 quantity 张，只为该批张数创建独立条件单，互不覆盖。
 * <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。
