I want to set up a commercial web site.
In this web site, I want to post a table that will include stock
quotes and indices, and the results of some calculations I want to do.
The calculations will use stock/indices quotes data. 

The problems: 
1. It is illegal to "redistribute" stock quotes.
2. I dont want to pay for the quotes...

The solution:
1. Post stock quotes links to web sites , such as yahoo or barchart
etc, in their free to use in websites format. (until here it is
legal).
2. Extract the data (stock/indices quotes) from my own web site page,
do the calculations, and post the results in my web page.

The question:
Is part 2 of the solution legal?
