/**
- * Gate 网格交易服务类。使用 Gate SDK 通过 REST API 下单。
+ * Gate 网格交易服务 — 策略核心。
+ *
+ * <h3>策略概述</h3>
+ * 多空双开基底 → 生成价格网格队列 → 条件单监控 → 触发成交后队列动态转移。
+ * 每根 K 线更新未实现盈亏（unrealizedPnl），平仓后累加已实现盈亏（cumulativePnl）。
+ *
+ * <h3>核心机制</h3>
+ * <ul>
+ * <li><b>条件开仓单</b>：使用 Gate API {@code FuturesPriceTriggeredOrder}，服务器监控价格，
+ * 达到触发价后以市价 IOC 开仓。相比限价单，条件单仅在触发价到达时才执行，避免提前成交。</li>
+ * <li><b>止盈队列</b>（longTakeProfitQueue / shortTakeProfitQueue）：每次网格触发时，
+ * 将新队列首元素加减 step 作为止盈价加入止盈队列。仓位推送回调中检测到净增张数后，
+ * 从止盈队列头部取出止盈价，创建止盈条件单。</li>
+ * <li><b>条件单 ID 集合</b>（currentLongOrderIds / currentShortOrderIds）：
+ * 用同步列表管理所有活跃的条件单 ID。每次网格触发时，取消对方方向的旧条件单（防止堆积），
+ * 再挂新的条件单。反向条件单的 ID 也存入对应方向集合统一管理。</li>
+ * <li><b>反向条件单</b>：当新网格首元素价格夹在多/空持仓均价之间，
+ * 且反向持仓张数不超过 3 张时，额外挂一张反向条件单并加入对方止盈队列。</li>
+ * </ul>
*
* <h3>状态机</h3>
* <pre>
- * WAITING_KLINE → (首次 K 线) → OPENING → ACTIVE
- * 双开失败 → STOPPED
+ * 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 + 初始条件单 + 止盈队列 → ACTIVE
*
* ACTIVE:
- * ├─ 仓位 size=0 且方向活跃 → REOPENING_L/S → ACTIVE
- * │ 补仓失败 → 重试 → 仍失败 → STOPPED
+ * ├─ 每根K线 → 更新 unrealizedPnl → 方向判断
+ * │ ├─ closePrice > longPriceQueue[0] → processLongGrid
+ * │ └─ closePrice < shortPriceQueue[0] → processShortGrid
+ * ├─ processShortGrid: 匹配空仓队列 → 队列转移 → 止盈入队 →
+ * │ 取消旧多仓条件单 → 挂新空仓+多仓条件单 → 条件满足挂反向多单
+ * ├─ processLongGrid: 匹配多仓队列 → 队列转移 → 止盈入队 →
+ * │ 取消旧空仓条件单 → 挂新多仓+空仓条件单 → 条件满足挂反向空单
+ * ├─ 仓位推送(净增张数) → 从止盈队列取止盈价 → 创建止盈条件单（plan-close-*-position）
+ * ├─ 平仓推送 → 累加 cumulativePnl
+ * ├─ 保证金安全阀 → 超限跳过挂单，队列照常更新
* └─ cumulativePnl ≥ overallTp 或 ≤ -maxLoss → STOPPED
* </pre>
*
- * <h3>架构</h3>
- * REST 下单委派给 {@link GateTradeExecutor}（独立线程池，避免阻塞 WS 回调线程）。
+ * <h3>队列转移规则</h3>
+ * <ul>
+ * <li><b>空仓队列触发</b>（processShortGrid）：matched 元素从空仓队列移除，
+ * 尾部递减 step 补充新元素；多仓队列以首元素（最小价）递减 step 生成新元素加入。</li>
+ * <li><b>多仓队列触发</b>（processLongGrid）：matched 元素从多仓队列移除，
+ * 尾部递增 step 补充新元素；空仓队列以首元素（最高价）递增 step 生成新元素加入。</li>
+ * <li>队列容量超限时截断尾部，保持固定容量。</li>
+ * </ul>
+ *
+ * <h3>止盈机制</h3>
+ * <ul>
+ * <li>网格触发时，新队列首元素 ± step 作为止盈价加入止盈队列。</li>
+ * <li>仓位推送检测到净增张数时，从止盈队列头部取止盈价创建止盈条件单。</li>
+ * <li>止盈条件单：以触发价监控（price_type=最新价，strategy_type=价格触发），
+ * 到达后以市价 IOC 平仓（reduce_only=true，price="0"）。</li>
+ * <li>止盈队列为空时兜底：entryPrice ± step 作为止盈价。</li>
+ * </ul>
+ *
+ * <h3>反向条件单条件</h3>
+ * <pre>
+ * newFirstPrice > shortEntryPrice AND newFirstPrice < longEntryPrice
+ * AND 反向持仓张数 < 3
+ * </pre>
+ * 满足条件时以 newFirstPrice 为触发价挂反向条件单，同时将 newFirstPrice ± step 加入对方止盈队列。
+ *
+ * <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。
