Checked against Nova's code on 2026-11-09

Open **Events tracker** in the left menu and click **Create event**. Give the change a title and the day it went live, and Nova shows your sales and net profit before and after that day.

## How do I add an event?

1. Click **Create event** above the chart, or hover over a day on the chart and click the **+** marker to create an event on that date.
2. Fill the form:

| Field | What to put |
|---|---|
| **Title** | What changed, such as "New main image". Required |
| **Date** | The day the change went live |
| **Category** | **Price change**, **Content change**, **PPC change**, **Product launch** or **Other** |
| **Scope** | **Accounts**, **Marketplaces**, **Parent ASIN**, **Child ASIN**. Every compatible value is included until you pick some |

3. Click **Create event**.

One event can cover several ASINs and marketplaces when it is the same change made the same day.

## How do I edit or delete an event?

In the list under the chart, click the pencil on the event's row (**Edit event**). The same form opens; change it and click **Update event**. The bin (**Delete event**) removes it after you confirm, and a deleted event cannot be restored.

## Can an event have an end date?

No. An event marks one day. To measure a promotion or a test that ran over several days:

- Click the event to open it, click **Custom** above its chart, set **Days Before Event** and **Days After Event** to the length of the period, and click **Apply**. **7D**, **30D** and **90D** split the window evenly around the event.
- To mark the day it stopped, log a second event, such as "Coupon ended".

## Who can add events?

Anyone who can open Events tracker, Workspace members included: no owner role is needed. Events are shared: everyone working on the same accounts sees them, and can edit or delete them.

## Where do events show?

On the Events tracker chart, as a marker on their date in the colour of their category. A marker showing **+1** or more holds several events; click it to open them. The list under the chart gives each event its sales and net profit trend around the date.

The Cockpit and Profit & Loss charts do not show events. If an event is missing from the list, its date is outside the date range at the top of the page, or a filter there leaves out its accounts, marketplaces or products: widen the range or clear the filters.
