Here is another plugin that lets you display and track stock portfolios on your website. Stock Portfolio Tracker lets your visitors create their own portfolios on your website and track their performance in real-time. It recalculates values every 10 minutes and can show profit/loss, volatility, and charts.
The Stock Portfolio Tracker plugin comes with 8 built-in color schemes. Your visitors will be able to share their portfolio with others with their own unique links. This plugin supports NASDAQ and NYSE but you can purchase Australian, Paris, and other markets.
