To search for a user or stock/crypto/forex/futures symbol, simply navigate to the top-left of every page. There, you will find a search bar, which you can click and perform your search.
As you search, you’ll get suggestions based on what you’ve typed in the search box. You can click on these suggestions and they’ll take you directly to their respective pages. (For instance, clicking Apple Inc. under STOCKS above would take you to the $AAPL page). You can also press VIEW ALL RESULTS for full search results.
These search results will show a more comprehensive list than the previous suggestions. You can sort them by STOCKS (stocks similar to what you typed in), PEOPLE, or TOPICS.
