Subject: [PATCH] 止损追单逻辑(多仓/空仓对称): 触发 → 查询 → 计算 → 下单 清理:取消相邻网格旧挂单 + 取消最远止盈单 一句话总结:每次止损触发补回 quantity*2 张,但总持仓不超 maxPositionSize,也不再累加放大。

 /**
- * 网格元素,表示网格交易策略中的一个价格层级。
+ * 网格价格层级,策略的最小操作单元。
  *
- * <p>每个网格层级包含该价格位置上的多仓和空仓挂单信息,
- * 通过编号和网格价格唯一标识一个网格层级。
+ * <h3>定位</h3>
+ * 每个 GridElement 对应网格中的一个价格点,同时持有该点的多仓和空仓挂单状态。
+ * 与传统的"价格队列+Map"模式不同,GridElement 将价格、方向、状态、订单ID 聚合到一个对象中,
+ * 并维护全局静态 HashMap 索引实现 O(1) 双向查询。
  *
- * <h3>关键字段</h3>
- * <ul>
- *   <li><b>编号</b>:网格层级的唯一标识</li>
- *   <li><b>网格价格</b>:该层级对应的触发价格</li>
- *   <li><b>多仓挂单</b>:是否已有多头挂单、多头挂单参数</li>
- *   <li><b>空仓挂单</b>:是否有空头挂单、空头挂单参数</li>
- * </ul>
+ * <h3>ID 体系与链表</h3>
+ * <pre>
+ *   ID ≦ -1:  空仓队列区域(降序),ID 自减,gridPrice 递减
+ *   ID  =  0:  基座位置,gridPrice = shortBaseEntryPrice
+ *   ID ≧  1:  多仓队列区域(升序),ID 自增,gridPrice 递增
+ *
+ *   链表: ... ← -3 ← -2 ← -1 ← 0 → 1 → 2 → 3 → ...
+ *         (通过 upId/downId + INDEX 实现 O(1) 遍历)
+ * </pre>
+ *
+ * <h3>字段分组</h3>
+ * <table>
+ *   <tr><th>类别</th><th>字段</th><th>说明</th></tr>
+ *   <tr><td>标识</td><td>id, gridPrice, upId, downId</td><td>编号、价格、双向链表指针</td></tr>
+ *   <tr><td>多仓订单</td><td>hasLongOrder, longOrderId, longTraderParam</td><td>是否有挂单、订单ID、完整参数</td></tr>
+ *   <tr><td>空仓订单</td><td>hasShortOrder, shortOrderId, shortTraderParam</td><td>是否有挂单、订单ID、完整参数</td></tr>
+ *   <tr><td>止盈</td><td>longTakeProfitOrderId, shortTakeProfitOrderId</td><td>止盈条件单ID</td></tr>
+ * </table>
+ *
+ * <h3>6 个全局 O(1) 索引</h3>
+ * <pre>
+ *   INDEX                 → findById(int)               ID → 元素
+ *   PRICE_INDEX           → findByPrice(BigDecimal)     价格 → 元素
+ *   LONG_ORDER_ID_INDEX   → findByLongOrderId(String)   多仓挂单ID → 元素
+ *   SHORT_ORDER_ID_INDEX  → findByShortOrderId(String)  空仓挂单ID → 元素
+ *   LONG_TP_ORDER_ID_INDEX→ findByLongTakeProfitOrderId(String)  多止盈ID → 元素
+ *   SHORT_TP_ORDER_ID_INDEX→ findByShortTakeProfitOrderId(String) 空止盈ID → 元素
+ * </pre>
+ * 索引通过 {@link #rebuildIndex(List)}(全量重建)或 {@link #refreshIndices()}(增量刷新)
+ * 维护,每次操作后自动打印全量网格状态到控制台。
+ *
+ * <h3>何时填充 TraderParam</h3>
+ * 初始化时 {@code updateGridElements()} 为每个元素预填充 longTraderParam 和 shortTraderParam
+ * (含 direction/entryPrice/takeProfitPrice/quantity),订单ID字段在挂单成功后由
+ * {@link GateGridTradeService} 的 4 个辅助方法写入。
  *
  * <h3>使用示例</h3>
  * <pre>
- *   GridElement element = GridElement.builder()
- *       .id(1)
- *       .gridPrice(new BigDecimal("2300.0"))
- *       .build();
- *
- *   // 挂多仓单
- *   TraderParam longParam = TraderParam.builder()
- *       .direction(TraderParam.Direction.LONG)
- *       .entryPrice(new BigDecimal("2293.7"))
- *       .takeProfitPrice(new BigDecimal("2301.6"))
- *       .build();
- *   element.setHasLongOrder(true);
- *   element.setLongTraderParam(longParam);
+ *   GridElement elem = GridElement.findById(1);
+ *   boolean hasLong = elem.isHasLongOrder();           // 是否挂了多单
+ *   BigDecimal tpPrice = elem.getLongTraderParam().getTakeProfitPrice();  // 止盈价
+ *   elem.getUp();     // 上一个网格(O(1))
+ *   elem.getDown();   // 下一个网格(O(1))
  * </pre>
