策略雷達的大戶買賣力數據有誤

小幫手您好  使用策略雷達  指定頻率為3分鐘   以下為程式碼  

SetTotalBar(600);
setbarBack(600,"D");


value1 = GetField("成交金額(元)", "D") / 100000000; 

condition1 = value1 >= 1;


condition2 = close >= average(GetField("收盤價","D"),20); 


value3 = ((close - GetField("參考價", "D")) / GetField("參考價", "D")) * 100;

condition3 = value3 >= 3;


value4 = GetField("買進特大單金額","D") + GetField("買進大單金額","D");
value5 = GetField("賣出特大單金額","D") + GetField("賣出大單金額","D");
value6 = (value4 - value5) / 10000;

condition4 = value6 >= 1000;  


if GetField("成交金額(元)", "D") <> 0 then value7 = ((value4 - value5) / GetField("成交金額(元)", "D")) * 100;

condition5 = value7 > -7.5; 



if CurrentTime <= 131244 and condition1 and condition2 and condition3 and condition4 and condition5

then Begin ret=1;

           RetMsg = text("     ", NumToStr(value6, 0),",            ", NumToStr(value7, 1) ," % ",",           ", NumToStr(value1, 2)," 億 ");
     End;


print(file("C:\print\print.log"),symbol,value4,value5,value6,value7,value1);


其中  大戶買賣力金額  有時會出錯  如附圖的(1762中化生,6472保瑞)

不知道是什麼問題  只有幾隻會出錯  而且通常在越早盤越容易有誤(如9點剛開盤時)

還煩請小幫手幫忙處理  謝謝
