# Manage rolling forecasts
Rolling forecasts continuously extend the forecast horizon. When actual data is available for a forecasted period, the forecast is closed, and the report displays the actuals.
### Close forecasts
Once a forecast is closed, it can no longer be edited. Forecasts should be closed as actuals become available.
{% hint style="info" %}
To hide closed forecasts, de-select **Period** > **Show Closed Periods**.
{% endhint %}
1. Go to **Model** > **Period**. Select **Close Period**.
2. If multiple forecasts exist, select the forecast for which the period should be closed.
3. Select the forecast period to close—current or previous year, quarter, or month. A custom period can also be specified.
1. Select **Preview.** The open and closed periods are displayed. Select **Save**.
The forecast is closed for January and cannot be edited.
### Extend forecast periods
As forecast periods are closed, new future periods are added to maintain a rolling forecast.
1. Go to **Model** > **Period**. Select **Close Period**.
2. Select the period to close.
3. Select **Extend Forecast Range** and set the duration.
4. Review the closed and open periods. Select **Save**.
As the open forecast for April 2026 is closed, a rolling forecast is created by simultaneously extending the forecast into 2027.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.fabricplan.com/documentation/plan/planning-sheets/how-tos/forecast-data-to-predict-future-trends/manage-rolling-forecasts.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
