用来统计在均线上或下的k线个数，逻辑上没问题，在最近6根k线上出现计算错误，

请帮忙看下问题出在哪里。

Vars

Natural Integer num1(0);

Numeric Length1(10);

Numeric avg1;

Events

OnBarClose(ArrayRef<Integer> indexs)

{

avg1=AverageFC(Close,Length1);

//Length1趋势判断

If(CurrentBar==Length1-1)

{

If(C<avg1)

num1=-1;

Else

num1=1;

}

If(CurrentBar>Length1-1)

PlotNumeric(\"qs1\",num1);
