如何寫排名增加前50名的語法

請問XQ小編，我修改了千張大戶的腳本，改成400張，想要設定只選出較上周增加大於1%的前50名

並由大到小排序，這時候我可以加上什麼語法呢？

input: offset(9999,"不用調整，相容用參數");

input: ratio(1.5, "增加比例%");

var:sameweek(0);

setbarfreq("W");

settotalbar(3);

if getinfo("FilterMode") = 1 then  

sameweek = 0 

else if 

datediff(GetFielddate("收盤價","D"),GetFielddate("收盤價","W")) < 6 

then  sameweek = 1 else  sameweek = 0; 

value1=GetField("大戶持股比例","W",param:=400)[sameweek];

if value1 > (value1[1] * (1 + ratio/100)) then ret=1;

outputfield(1, Value1-Value1[1],  2, "差異%");

outputfield(2, value1, 2, "大戶比例");

outputfield(3, value1[1], 2, "上周大戶比例");

謝謝小編

另外，我想要再加上其它條件來優化選股，增加了關鍵券商，地緣券商及內部人持股比例

可是不知道哪邊寫錯了，編譯都沒有問題，但是跑出來都沒有符合…可以麻煩小編幫我看一下嗎？

謝謝小編

value1=GetField("關鍵券商買賣超張數","D");

value2=GetField("地緣券商買賣超張數","D");

if GetField("內部人持股比例","M")

>=GetField("內部人持股比例","M")[1]

and GetField("大戶持股比例","W",param := 400)

>=GetField("大戶持股比例","W",param := 400)[1]+0.5

and value1>=0

and value2>=0

then ret=1;

outputfield(1,GetField("內部人持股比例","M"),0,"內部人");

outputfield(2,GetField("內部人持股比例","M")[1],0,"前期內部人");

outputfield(3,value1,0,"關鍵券商");

outputfield(4,value2,0,"地緣券商");

outputfield(5,GetField("大戶持股比例","W",param := 400),1,"400張大戶比例");

outputfield(6,GetField("大戶持股比例","W",param := 400)[1],1,"前期400張大戶比例");
