請問這如何修改成周線?

這是我從其他發問中找到的程式碼

請問我如何修改區間成週線判斷?

謝謝

input:length(15,"天期"),_Change(5,"漲幅(%)");

value1 = highest(high,length);

value2 = lowest(low,length);

condition1=trueall(AbsValue(GetField("漲跌幅"))<_Change,length);

condition2=trueall(close <= value1,length);

condition3=trueall(close >= value2,length);

if condition1 and condition2 and condition3 then ret=1;

outputfield1(GetField("漲跌幅")[length],"漲幅(%)");

outputfield2(value1,"N天最高點");

outputfield3(value2,"N天最低點");
