New to computer trading

[dhawkins@xxxxxxxxxxxx (Drew Hwakins)]

I am new to computer trading and would like some advice before wasting lots of money on software. I am in the process of purchasing the metastock  program and would like to what I need to download information from the different exchanges in the world. Also how to access this information once a day basis.
                                               Thanks in Advance
