+/**
+ * 平仓频道处理器。
+ *
+ * <h3>数据用途</h3>
+ * 每笔平仓发生时推送 pnl（盈亏金额），累加到 {@code cumulativePnl} 用于判断策略停止条件：
+ * cumulativePnl ≥ overallTp（达到止盈目标）或 ≤ -maxLoss（超过亏损上限）。
+ * 止盈由 Gate 服务端条件单自动触发，平仓后仓位变为 0，盈亏通过本频道推送。
+ *
+ * <h3>推送字段</h3>
+ * contract, side（long / short）, pnl（该次平仓的盈亏，如 "+0.2" 或 "-0.1"）
+ *
+ * <h3>注意</h3>
+ * 平仓盈亏来自服务器端，不受本地计算误差影响。这是策略停止的唯一盈亏判断来源。
