想詢問漲幅問題寫法

想找出同一支標的一週漲幅變化。

input:period(10,"計算區間");

condition1 = CLOSE > OPEN ;

if condition1 THEN 

begin

      RET=1;

END;

value2=GetField("最新股本");

value3=GetField("月營收年增率","M");

value4=GetField("股價淨值比","D");

outputfield(2,value2,0,"股本(億)");

outputfield(3,value3,1,"月營收年增率");

outputfield(4,value4,1,"股價淨值比");

outputfield(5,value5,1,"當天漲幅");

outputfield(6,value6,1,"2日漲幅");

outputfield(7,value7,1,"3日漲幅");

outputfield(8,value8,1,"4日漲幅");

outputfield(9,value9,1,"一週漲幅");

value5 = ((close-open)/open)*100;

value6 = ((close[1]-open[2])/open[2])*100;

value7 = ((close[2]-open[3])/open[3])*100;

value8 = ((close[3]-open[4])/open[4])*100;

value9 = ((close[4]-open[5])/open[5])*100;

發現從 當天漲幅開始到一週漲幅就開始亂掉。

譬如說位速 10%，卻顯示-10... 請問語法上需要怎麼修改

另外能否請教流通在外股數，是否也能寫上？
