"大戶散戶籌碼"

想確認大戶散戶籌碼流向是否可以在交易編輯內使用?(因為在回測時無法回測)

//大戶散戶籌碼流向

if barfreq <> "Min" and barfreq <> "D" and barfreq <> "AD" then 
    raiseruntimeerror("僅支援分鐘與日頻率（含還原）");


value111 = GetField("賣出特大單量","D") + GetField("賣出大單量","D");
value222 = GetField("買進特大單量","D") + GetField("買進大單量","D");
value333 = value222 - value111;
value444 = GetField("賣出小單量","D");
value555 = GetField("買進小單量","D");
value666 = value555 - value444;
Value777 = value333 - value666;

程式如下
