You can use a stock price API service and Custom Metrics to show your stock watchlist prices in Momentum.

How-to add a stock metric

Note: For a stock price API service, we are currently recommending Polygon.io. There are other services, so please use whichever you prefer. This guide is tailored to Polygon, but other services will work in a similar fashion.

1. Create a free account at Polygon.io and log in.
2. Copy your API key on the API Keys page in Polygon.
3. Get the stock ticker symbol for the stock you want to track. You can use Google to find it—for example, if you'd like to find Apple's ticker symbol, you can search for "Apple stock". The stock ticker will appear below the company name in the search results. In the case of Apple, it's "AAPL".
4. In Momentum, click on + Add → Metric (or open Metrics and click the + icon).
5. Choose the From a URL option.
6. Give your metric a name, e.g., "Apple".
7. Enter the API URL for the stock price, e.g.: 

   https://api.polygon.io/v2/aggs/ticker/AAPL/prev?apiKey={Insert your API Key here}

8. In the Value section, select results[0].c, which is the daily close price. You can double check that the .c value matches the close price of the stock to be sure.
9. If you'd like the metric to always show on your dash, click Pin to dashboard.
10. Click Save. Your new stock metric will now continuously update in Momentum!

If the stock price metric is not working for you, double check that you have inserted your API key into the URL in step 7 above.
