Developer here: I’ve built an Excel Add-In which feeds live financial data to cells via simple formulas. It currently sources data from Yahoo Finance and IG Index, I am working on other data providers.<p>For example to populate a cell with the latest Apple stock price: =EPF.Yahoo.Price(“AAPL”)<p>For brokers, such as IG Index you can download historical data for analysis, submit trades and stream real-time prices to cells.<p>I have some users using it to automatically keep track of the value of their portfolio across different brokers and I'm also helping one guy working on an automated trading system in Excel.<p>Here's a tutorial on using it to build a realtime investment portfolio.
