TrendSpider.com is a simple to use charting and indicator engine. You can test out indicators and parameters to refine your trading strategy's buy/sell engine. After performing a strategy test, you can set it for live trading alerts to help trigger buy/sell action. I use their easy to see charts in my presentations and website.
An alternative to Amazon.com books with free delivery worldwide. A UK based operation with outlets around the world, I found the price of my own book, Panic-Proof Investing, less expensive here than on Amazon.
