I'm signing up with optionsxpress.ca to trade in stocks and options and was wondering if it was safe. This is the first time I've done this, and I want to make sure I'm not getting duped or putting myself at risk. They are asking for the following: 1) A deposit check ($1000) 2) A photocopy of my driver's license (front and back) 3) My SIN # (Canadian equivalent of Social Security number?) And all the other typical pieces of information: name, address, phone number, date of birth, etc. I'd be mailing this info by Fedex. Anyone see any problems?
