Variables retain their values from bar to bar so if you assign a variable to a value, you can use that variable on any subsequent bar. You can also declare arrays of one or two (and possible more) dimensions. (Three dimensional arrays did not work with TS4.0 but may work in TS2000i.)
In the following code:
Input: Length(10), XYZ(0), Slope(0);
Vars: Factor(2 / (Length + 1)), j(0);
Array: MyArray[10](0);
if CurrentBar = 1 then begin
for j = 0 to 10 begin
MyArray[j] = j;
end;
end;
XYZ = MyArray[6] * Factor * Close;
Slope = XYZ - XYZ[10];
The variable "Factor" is initialized to a calculated value as part of the declaration. The eleven values assigned to the array elements are initialized on the first bar and retain their values for all subsequent bars (or until you change their values).
The variable XYZ is calculated on every bar and will have different values depending upon the closing price on each bar. Past values of XYZ are available. The equation for Slope refers to the value of XYZ 10 bars back.
A bit confusing - but it works.
