/**
 * 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
 * Gate 网格交易服务 — 策略核心。
 *
 * 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</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>未实现盈亏公式（正向合约）</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 + 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
 * </pre>
