Introduction: The Rise of Online Trading

The stock market has always been a cornerstone of wealth creation in America, but the way people access it has changed dramatically. Gone are the days of calling a broker to place trades. Today, online platforms put the market at your fingertips—whether you’re on a desktop or a mobile app.

With dozens of platforms competing for attention, each promising low fees, advanced tools, or sleek apps, the challenge is choosing the one that fits your goals.
