# Maintain Market Indices and Market Index Values

## Market Indices List

Here, you are able to view a list of market indices based by their name, code and category. You can use the [filtering- and sorting options](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/sorting-and-filtering-lists) (you can also sort on the list headers), including filtering on *disabled* market indices:

Click on a list item to open up the Market Index drawer (see below).

You also have other actions, such as [customise columns](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/customising-list-columns).&#x20;

## Market Index Drawer

The first tab, Overview, is separated into:

* a Main Details section, and
* a Market Index Values section

See below picture for reference.&#x20;

### Maintain the Market Index Values

For each market index, you can view a list of the connected market index *values*. On the below grid, you can view, edit, create, delete, sort, filter, customise/search for and export market index values for each row:

The Last Updated field shows the date of when the most recently updated market index value was updated.
