StockCharts.com does not allow the use of aliases, pseudonyms or company names for the official name on a user's account. Our various data vendors require that we collect actual names for compliance purposes. We also must ensure that each account is only used by one individual; having a person's real name associated with their account helps us with that requirement.
In addition, real names must be used if you choose to publish a Public ChartList. If an author isn't willing to put their real name by their list, we are not willing to publish their charts. Real names give the lists credibility and reduce the amount of chart-spamming that might otherwise occur.
