FAQs about our Comparators

 1. Why choosing the right online broker is key to success?

Your broker is more than just a platform—it’s your gateway to the financial markets. A well-chosen broker protects your assets, keeps your costs low, and encourages long-term, responsible investing. The wrong one can expose you to hidden fees, limited access, poor service, or even a risky behavioral influience. Making the right choice early saves time, money, and stress down the line.

 


 

2. How does PIA evaluate online brokers?

We apply a data-driven, independent evaluation model built around 14 core categories such as asset safety, cost structure, platform design, transparency, and educational support. For each broker, we collect and analyze data points, sourced from online research, platform testing and regulatory filings. 

 


 

3. How does PIA finance itself?

Private Investor Alliance fees through affiliate partnerships with some of the presented brokers.
