I was a trader in the gold exchange several years back. At that time, I used http://money.net which was free and this http://www.kitco.com/ But I also had an Ameritrade account so that I could do live streaming quotes. Try getting a http://Yahoo.com account set up and start looking in the "Finance" section for gold stocks.
Like this one https://finance.yahoo.com/quote/nem?ltr=1.
Start communicating with like minded-buyers on that forum who will provide you with ticker symbols for other penny stocks or low cost stocks.
Gold is a great investment whether you are in the stock purchases or bullion purchases directly from them like http://kitco.com
The purpose of having an Ameritrade account is to do online trading and buying of stocks. To do this requires a money market account with a certain balance amount required. I believe Ameridtrade's minimum balance requirement would be $1500.00. That may have changed to attract new clients. More here on that https://www.scottrade.com/
Furthermore, you need to be early in the morning (depending on what time zone you are in) as the New York Stock exchange opens at 6 am ET. Find a live streaming quotes website like http://money.net and starting watching your stocks.
Also, I suggest you get yourself a book called Barrons Financial Guide Dictionary of Finance and Investment Terms 7th Ed. to get yourself acquainted and educated with the terminology used.
