Sorry I don't understand you. QP2 itself is a data source while HQuote/Yquote is a software tool used to download data from Finance yahoo. If you pay $25US every month, you have your data as well as download/database update software. Again as I mentioned before, if you're serious trader, free datasource like Finance Yahoo is not reliable, a single data error, which is very likely because there's no data QA at all, could cost you a year of comercial data subscription fee. I learnt it hard way.
