## Accessing the Index Catalog <a href="#accessing_the_index_catalog" id="accessing_the_index_catalog"></a>

The Index Catalog can be accessed from the StockCharts' [Symbol Catalog](https://stockcharts.com/freecharts/catalog/). On the Symbol Catalog page, scroll down and click the “Index Catalog” link at the bottom of the page. A direct link to the Index Catalog is [here](https://stockcharts.knack.com/symbolcatalog).
