代码如下：

Vars

Series<Numeric> low_num;

Series<Numeric> high_num;

   OnBar(ArrayRef<Integer> indexs)

{

       if(low<low[1] and Low[-1]>=Low)

{

low_num=low;

PlotNumeric(low_high,low);

}

if(high>high[1] and high[-1]<=high)

{

high_num=high;

PlotNumeric(low_high,high);

}

Commentary(low_num[0]:+text(low_num[0]));

Commentary(low_num[1]:+text(low_num[1]));

Commentary(low_num[2]+text(low_num[2]));

Commentary(high_num[0]+text(high_num[0]));

Commentary(high_num[1]+text(high_num[1]));

Commentary(high_num[2]+text(high_num[2]));

}

序列变量加了条件判断，想把不是阶段最高低的位置去掉，现在查看下来每一根都有值，不赋值就给上一根。想在十字位置拿到第2个前高的值3821，但是拿到的是3834，该怎么拿到我箭头标记的第2根高点呢？
