The Forward Curve Expression makes it very easy to create straight forward curves as well as expressions/spread curves.
Example: Entering CL in Formula field would produce the same Forward Curve as entering CL in the "Add Forward Curve Dialog.
Example: Entering (XRB * 28 + HO * 14) - CL would produce a 3x2x1 Forward Curve
Shift Function
We also have a Shift command that will allow you to create various types of Spread Curves.
Example: Entering CL-SHIFT(CL,1) would produce a Curve where your data points are:
CL 1!-CL 2!
CL 2!-CL 3!
CL 3!-CL 4!
Etc.
When using the Shift Command the first value is Root, second value is number of forward ahead to shift, Example:
