美股XS漲跌幅

您好，想請問為什麼自選的漲跌幅結果和XS得出的結果不一樣?

另外請問美股XS是不能選出季和年的資料嗎?

XS程式如下：

if C >0 then ret=1;

outputfield1(getField("收盤價", "D"),"收盤價");

outputField2(getField("漲跌幅", "W"),"週漲跌幅");

outputField3(getField("漲跌幅", "M"),"月漲跌幅");

//outputField4(getField("漲跌幅", "Q"),"季漲跌幅");

//outputField5(getField("漲跌幅", "Y"),"年漲跌幅");
