I just use yahoo finance for real time quotes. We have the ability to purchase streaming quotes through the NetExchange Pro platform and for full blown Streaming Real-Time quotes it costs $33.75/week. Charts range from $3.25-$9.50 a week.

IMHO, unless you do a lot of stock business, you don't need to pay for real-time streaming quotes.  We have them at Jones, and I only use them because they are there - if I didn't have them I wouldn't miss them.

Yahoo Finance also has an upgraded Premium Real-Time quote feature for like 13.95/month (in addition to their free website).

I would strongly suggest taking a look at MarketQ or Quodd.  I know what they cost for LPL advisors but I would hate to quote because other affiliations may not have the same deal.  Beware that you pay two different fees, one for the quote service and the other are the exchange fees.  You could also take a look at FreeStockCharts.com by the Worden Brothers.  They have great charting and use free real time quotes but with an ad banner unless you are a subscriber.

If you do some big numbers (or want to) and are planning to actually manage money, nothing is better than a Bloomberg terminal and ESignal charts.

Look at Quodd.  You can call them at 866-537-5518.  They will typically let you try their system for free for a couple of weeks to see if you like it.  All you need is access to the internet.  They just launched a new charting system today, it's good stuff.  I get a discount from my BD and pay only $50 per month for real time quotes.  You also would need to pay for exchange fees to get feeds from NASDAQ, OPRA, NYSE, and AMEX that will probablt run you about $100 per month.

I pay 30/month for RT NYSE/AMEX/NASDAQ

Not sure if listing this as a non-professional vs pro changes the price plan, I think it does but not sure.

My wife actually opened the account during my set-up process.
