			/**
			* Gate 网格交易服务类，使用 gate-api SDK 进行合约下单。
			* 策略：多空双开 → 设置止盈止损点位 → 网格循环交易
			* 网格交易策略引擎 — 多空对冲网格。
			*
			* 测试参数：
			* 品种: XAU_USDT（黄金）
			* 杠杆: 100x（全仓）
			* 数量: 0.01 XAU
			* 网格: 0.0035（千分之三点五）
			* 整体止盈: 0.5 USDT
			* 循环次数: 3
			* 报警: 本金亏损 15%（初始本金 50 USDT）
			* <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，基价×(1−gridRate) 等比向下）
			* ├── generateLongQueue() ← 多仓价格队列（升序，基价×(1+gridRate) 等比向上）
			* ├── 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 ← 首档间距（0档与±1档的距离度量）
			* minTick = 10^(-priceScale) ← 交易所最小价格单位
			* 等比网格: 下一档 = 本档 × (1 ± gridRate) ← 向下×(1−r)，向上×(1+r)
			* 止盈价 = 本档价 × (1 ± gridRate)（与相邻网格价联动） ← 多仓向上，空仓向下
			* 单笔盈利 ≈ 档价 × gridRate × contractMultiplier × quantity（随网格位置浮动）
			* </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。
