How to see the primary listed symbols for the relevant market? (What is the “Primary Listing” filter for?)

In many markets covered by our Stock Screener, the table not only contains the primary listed companies for that market but might also contain companies listed on that market as an additional or optional placement. 

For example, AAPL's primary listing is on the U.S. Nasdaq exchange. However, the company also lists its ticker on other international exchanges, such as the Italian market.

If you want to filter out these additional symbols, we have introduced a "Primary Listing" filter. You can find it in the filters dialog or the market dropdown filter.

If you only want to see symbols with their main listing in the Italian market, you can:

1. For the quickest filtering, just click the Market pill and move the slider to the on position. You will see the Crown icon, which means the main listing filter results.
   
   
   
   
2. You can add a separate filter: click the "Add Filter" button on the top bar and select the "Primary Listing" filter.
   
   And select option "Yes" in the "Primary Listing" filter to exclude optional additions like AAPL from your list.
