Show HN: Trade the stock market using javascript in a browser

I built www.StockTesting.com It allows anyone to trade or test strategies on the stock market with Javascript, all from within your browser. You can see charts of your backtesting strategies from the last 10 years, or even set your strategy to autotrade the market and update your phone by text message, voice call, or email. You can do this all just by calling a function from within your javascript code (eg) : call_my("cell","555-1212", "Just sold my shares for a cool profit of $"+profit);
