Yes, the library is the best place. You might try limewire file share also. But be careful you don't get a computer virus. Scan all the files you download from there before you open them.
do a search on google there are lots of websites with free info on TA do a search on this website you will find useful discussions on TA -- the explanation and implementations are better than many books.
If you want to be successful at this business, treat it like a business, and all businesses have expenses, and your education needs the best materials you can get. I strongly suggest picking up Trading in the Zone by Mark Douglas on Amazon, it's less than 20 dollars now I think when I last checked.
