If you pass series 7, you end up paying somthing extra like $300 EVERY month for intraday datafeed and plateform charges, in case you decide to go retail and not to go prop firm, i could be wrong www.stcusa.com
Did you try typing "Series 7" into Google or Wikipedia? Usually a good way to start... http://en.wikipedia.org/wiki/General_Securities_Representative_Exam
Hey Beast, A series 7 license basically allows individuals to SELL securities to retail customers. The test is about six hours and covers stocks, bonds, options, limited partnerships, and investment related products. You need to be sponsered by a member firm in order to take the test. In a nutshell, if you want to work for a firm that sells investment products/services to retail customers then you will need a series 7 license. Hope this helps!
