XS策略結果異常

僅用下方條件跑選股，結果與XQ特別報價漲停股比對並不相同，

 input: Length(20),d(2),thre(9.2),volthre(500);

variable: bb(0),checkbb(0);

SetInputName(1, "布林週期");

SetInputName(2, "布林標準差");

SetInputName(3, "漲幅門檻");

SetInputName(4, "成交量門檻");

value1 = Close;//收盤價

value2 = Low;//K最低價

value3 = Open;//K開盤價

value4 = High;//k最高價

value5 = GetField("漲跌幅");

//漲跌幅>=門檻

if value5 >= thre and volume >= volthre then

begin

//計算布林

bb = bollingerband(close,Length,d);

//初始化是否站上布林之參數，預設0沒站上BB

checkbb = 0;

if close cross over bb then checkbb = 1;

ret = 1;

end;
