To buy or sell shares, you need a brokerage account. There are a variety of brokerages you can sign up with, so it’s best to do some research to determine which one appeals the most to you.
You can initiate the process of buying or selling (or short selling or buying back) recommended shares in the Stockfox app by hitting the Buy or Sell (or Short Sell or Buy Back) buttons displayed at the bottom of each tip.
