迴圈(Loop)

for迴圈與To搭配使用:
與To搭配使用，Counter的值從IValue開始，每執行一次迴圈，Counter的值就加一，直到大於FValue，則離開迴圈不再執行。

For Counter=IValue To FValue Begin
  I1;
  I2;
End;

for迴圈與DownTo搭配使用:
與DownTo搭配使用，Counter的值從IValue開始，每執行一次迴圈，Counter的值就減一，直到小於FValue，則離開迴圈不再執行。

For Counter=IValue DownTo FValue Begin
  I1;
  I2;
End;

For BarBackNo = 0 To 9 Begin
    HighPriceSum = HighPriceSum + High[BarBackNo];
End;

For BarBackNo = 9 DownTo 0 Begin
    HighPriceSum = HighPriceSum + High[BarBackNo];
End;

While Logical_Expression Begin
  I1;
  I2;
  I3;
End;

Where:
Logical_Expression – 邏輯陳述句
I – 邏輯陳述句為真時，會執行的指令

BarBackNo = 0;
While BarBackNo < 10 Begin
  HighPriceSum = HighPriceSum + High[BarBackNo];

  BarBackNo = BarBackNo + 1;
End;
