近五年平均最高現金殖利率

value1=Highest(getfield("現金股利殖利率","D"),200);

value2=Highest(getfield("現金股利殖利率","D"),400);

value3=Highest(getfield("現金股利殖利率","D"),600);

value4=Highest(getfield("現金股利殖利率","D"),800);

value5=Highest(getfield("現金股利殖利率","D"),1000);

value6=(value1+value2+value3+value4+value5)/5;

ret=1;

outputField1(value1,"近200天最高現金殖利率");

outputField2(value2,"近400天最高現金殖利率");

outputField3(value3,"近600天最高現金殖利率");

outputField4(value4,"近800天最高現金殖利率");

outputField5(value5,"近1000天最高現金殖利率");

outputField6(value6,"近五年平均最高現金殖利率");

每200天為一個區間, 為什麼output data都會一樣數字?
