全日盤買賣力均量分開計算

小幫手你好：

1. 我用time >= 150000 AND time < 050000 和  time >= 084500 and time < 134500 

想分別計算當時段的買賣力均量

可是執行後，數據全部都是0

2. 想要在每天的1500和隔天0845對累加內外盤量重新計算(歸0)

已經用了不同的變數區分  var:vol_1500(0);   var:vol_0845(0);

可是結果還是會累加到之前的資料

麻煩小幫手幫忙看一下，謝謝

以下為程式碼：

var:vol_1500(0); //夜盤的累加內外盤

var:vol_0845(0); //日盤的累加內外盤

if symbolexchange <> "TW" and symbolexchange <> "TF" then raiseruntimeerror("不支援此商品");

if SymbolType <> 2 and SymbolType <> 3 and SymbolType <> 5 then raiseruntimeerror("不支援此商品");

if barfreq <> "Min" and barfreq <> "D" and barfreq <> "AD" then 

raiseruntimeerror("僅支援分鐘與日頻率（含還原）");

//if date <> date[1] then begin

if time >= 150000 AND time < 050000 then begin

value1 = GetField("外盤量","D");

value2 = GetField("內盤量","D");

value3 = value1 - value2;

vol_1500 = summation(value3, 840); //夜盤共有840分鐘

value79 = getField("外盤成交次數", "D") + getField("內盤成交次數", "D");

if value79 = 0 then 

value89 = 0

else 

value89 = (vol_1500 / value79)*100;

end;

if time >= 084500 and time < 134500 then begin

value1 = GetField("外盤量","D");

value2 = GetField("內盤量","D");

value3 = value1 - value2;

vol_0845= summation(value3, 300);

value79 = getField("外盤成交次數", "D") + getField("內盤成交次數", "D");

if value79 = 0 then 

value89 = 0

else 

value89 = (vol_0845 / value79)*100;

end;

//end;

Print( "datetime", datetime, "內外盤", value3, "累加內外盤量0845", vol_0845, "累加內外盤量1500", vol_1500,"成交次數", value79, "avg", value89);

plot1(value3,"買賣力");

plot2(value1,"外盤量",checkbox:=0);

plot3(value2,"內盤量",checkbox:=0);

plot4(value89,"均線",checkbox:=0);
