## Pricing Data Editor

In Financial Model Builder a tool is implemented to ensure that the data structure is coherent. The tool makes it easier and intuitive to build the pricing data file. This tool is called the Pricing Data Editor.

The goals of this Pricing Data Editor are:

• Simplified comprehension of the pricing data file by hiding the complexity of the representation.
• Simplified editing of the pricing data file while keeping the consistency.

The Pricing Data Editor is available while opening a pricing data file. It works by parsing the file and presenting the information in the several tabs, at the bottom of the editor. If you want to learn more about the scenario concept, more details are available in the Parallelization Tutorial.

Currently, the Pricing Data Editor supports data0D and data1D type of data.

### Scenarios Tabs

In order to illustrate the features provided by this tool, you use the pricing data file IRS.scn provided in the Interest Rate Swap Tutorial. If you double-click the pricing data file, you can automatically visualize the decomposed scenario data in the Scenarios tab, with the input yield curves.

If you click one of the yield curves, such as the discount_Libor_3M curve, you can visualize the associated scenario data, historical data, and meta data in the top tab.

Above the yield curves, the three icons enable to Add, Update and Delete your pricing data file.
