import java.util.concurrent.ConcurrentHashMap;
/**
- * 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>
