以下指標程式可否幫我檢查為何我編譯完後主圖指標無法顯示?

input: Len1(20,"期數"), Len2(120,"期數");

variable: m1(0), m2(0);

variable: rsv(0), k(0), _d(0);

SetTotalBar(maxlist(9,6) * 3);

Stochastic(9, 3, 3, rsv, k, _d);

m1=average(close, len1);

m2=average(close, len2);

if close> m1 and close> m2 and m1> m2

then condition11=true

else condition11=false;

condition12= k < _d;

condition13= k[1] > 75;

if condition11 and condition12 and condition13 then plot1(low, "賣出放空");

if close< m1 and close< m2 and m1< m2

then condition21=true

else condition21=false;

condition22= k > _d;

condition23= k[1] < 25;

if condition21 and condition22 and condition23 then plot2(high, "買進回補");
