# Historical Forward Curves
How to view a forward curve as of a past valuation date in the BlueGamma web app and download the current and historical curves together.
### **1. Log In and Navigate to Interest Rate Curves**
* Log in to [BlueGamma](https://app.bluegamma.io/).
* If you don't already have an account, [Sign up for a 14-day free trial](https://auth.bluegamma.io/sign-up).
* Click [**Interest Rate Curves**](https://app.bluegamma.io/interest-rate-curves/usd) in the left-hand navigation menu.
***
### **2. Select Your Currency and Curve**
* Use the **currency drop-down menu** in the top-right corner to select the desired currency (e.g., GBP, USD, EUR).
* Use the **index drop-down** next to it to pick the curve, for example SOFR or 6M EURIBOR.
***
### **3. Enable Historic Forward Curves**
1. In the **top-right corner**, click the **Valuation Date** picker and choose a past date.
2. The historic curve is overlaid on the chart alongside the **Current Forward Curve**. Pick more dates to add more curves, or click the refresh button next to the picker to clear them.
***
### **4. Download the Historic Forward Curve**
* Click the download button (for example **Download SOFR Curve**) to export the current and historic forward curves together, one for each date on the chart.
* Up to four curves download together: the current curve plus three past dates. With more on the chart, the button suggests the Excel Add-in instead.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://www.bluegamma.io/documentation/market-data-guides/forward-curves/downloading-historic-forward-curves.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
