Can I actually open an account online?
Yes, you can open an account with many brokerage firms online; however, in most instances your account will not be active until the brokerage firm receives and processes a signed application from you. Note that some firms allow for the use of electronic signatures, while others will require a manually (hand written) signed document. Some firms will gather basic information for your account over their Web Sites, then mail you the pre-completed application for you to sign and return. Please make sure to check with your brokerage firm for information on specific guidelines.
Is there still a brokerage firm involved or do I really bypass the broker completely?
