For decades, stock traders have used massive archaic terminals created by Michael Bloomberg to message other traders, read the news, and get real-time global financial data. This product was initially designed in 1981, and few changes have been made to the product since then.
Fast forward 40 years. Reddit and TikTok are providing
their ability to manipulate the market, Elon's tweets have so much impact on stock prices someone made a tool
to notify you when that happens, and instead of needing to call a broker, people can make these trades for free on Robinhood.
The craziest part is cost. Reddit and TikTok are free. A Bloomberg Terminal is $20,000 per year
per user. An old tool has remained dominant even though technology has rapidly evolved.
Enter Didier Lopes. He, along with 6 other engineers created a tool that scrapes Reddit, Twitter, and other platforms to measure market sentiment and provide real-time technical analysis. It's basically
a Bloomberg Terminal that's free (though it's all just in Python... for now).
This isn't just a new tool, it's a response to a shift in consumer behavior around stock trading. As our behavior shifts, someone ends up making technology that changes with us, be it the market leader or a new player.
TL;DR - If your product doesn't adapt to change, someone else will.
