Manage Calculations

You can manage the Eagle Analytics calculations used by the standard FINCAD functions for option-adjusted spread, duration, and convexity analytics, as well as the functions for duration, mod duration, convexity, mod convexity, and basis point value computations. You can view/edit, create, duplicate, and delete calculations.

Calculations are initialized with imported Eagle package files and conventionally use the same naming convention as the underlying FINCAD function. The best practice is to duplicate an imported calculation and then apply any customizations to the copied calculation.

View / Edit a Calculation

You can view and edit several calculation attributes, including the calculation name, description, and the FINCAD function used. You can override input arguments used with calculations. Eagle recommends that you do not apply changes directly to the original calculation files. Use copied calculations to preserve the integrity of the initial Eagle Analytics migration package.

In the Setup workspace, click Calculations in the left navigation pane.
You see the Calculations workspace with the list of all available calculations.
Scroll down to the calculation you wish to view or edit.
