為何空單進場腳本未觸發賣出，出場腳本會先觸發買進？

進場腳本：

input: averageVolume(1000);

variable:rsv_d(0), KK(0), dd(0); //宣告3個參數

stochastic(40,3,3, rsv_d, KK, dd); //XQ內建寫好的KD函?==>呼叫他

value1 = average(close,60);

value2 = LinearRegSlope(value1,60);

Value3 = q_Last;//成交價

value4 = average(GetField("Volume", "D")[1], 5);//"5日均量"

condition1 = KK < 40 and KK[1] >=40 and KK[2] >=40 and KK[3] >=40;

condition1 = close < value1;

condition2 = close[1] >= 20 and value4 >= averageVolume;

condition3 = close < close[1];

condition4 = value2 > 0;

condition5 = value2 < value2[1] ;

condition6 = close cross above average(close,20);

condition7 = KK cross above 20;

//進場

variable:byin(false),byprice(0);

if byin=false and condition1 and condition2 and condition3 and condition4 and condition5

then

   begin

   byin=true;

   ret=1;

   byprice=close;

   end;

{//出場

if byin=true and condition6 or condition7;

   begin

   byin=false;

   ret=1;

   end;

//尾盤出場

if byin=true and time > 132400 and volume > 0 then

   begin

   byin=false;

   ret=1;

   end;}

   

print(time,rsv_d, KK, dd,byin,byprice,condition1,condition2,condition3,condition4,condition5);
