+/**
+ * 仓位频道处理器。
+ *
+ * <h3>数据用途</h3>
+ * 监控仓位数量（size）和入场价（entry_price）。
+ * 有仓位时（size.abs > 0）：标记方向活跃，记录入场价 → 基底首次成交记录基底入场价并等待生成网格队列，
+ * 非基底成交立即设止盈条件单。无仓位时（size=0）：标记方向不活跃。
+ *
+ * <h3>推送字段</h3>
+ * contract, mode（dual_long / dual_short）, size（正=多头，负=空头），entry_price
+ *
+ * <h3>注意</h3>
+ * 双向持仓模式下空头 size 为负数，使用 {@code size.abs()} 判断是否有仓位。
+ * 累计盈亏不由本频道计算，而是由 {@link PositionClosesChannelHandler} 独立处理。
+ * 止盈条件单由服务端自动触发平仓，本频道不负责开仓操作。
