The SimpleScore is our proprietary scoring metric to compare products and services at The Simple Dollar in a transparent, evidence-based way. Our editorial team identifies five quantifiable aspects to compare for every brand, determines the rating criteria for each aspect score, then averages the five aspect scores to produce a single SimpleScore. For day trading platforms, we compared mobile apps, product offerings, broker resources, customer support and customer satisfaction for every major day trading platform. Our ratings are meant to be a directional tool to help you in the process of choosing a day trading platform. Be sure to continue your research and shop around for the best day trading platform that fits your specific needs.
