 /**
  * 仓位频道处理器。
- * 私有频道,需认证。解析仓位推送后回调 {@link GateGridTradeService#onPositionUpdate}。
+ *
+ * <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。
