Broker evaluations and testing methodologies

Broker evaluations at are based on our collected quantitative data as well as the qualitative observations and opinions of our expert researchers.

Our evaluation process begins with a comprehensive analysis and assessment of the broker's products and services. We examine all aspects of the broker's offering that may be of interest to the broker's customers. This involves a deep dive into all websites operated by the broker, all available content across a variety of mediums, and rigorous testing of the broker's proprietary tools and/or software. All of this research informs our ultimate scores.

Additionally, we consider a broker's regulatory status, which helps us determine whether you should trust the broker to keep your money safe.
