I am fairly new to Quantopian and but not new to algorithmic trading and developing. I have noticed that the bulk of ideas and focus here is on fundamental analysis to take trades. If anyone would like to get some fresh ideas about how to successfully trade algos I suggest a book by Kevin Davey "Building winning Algorithmic Trading Systems" (found on Amazon). He has personally won international trading contests. The bulk of his trading algos are not based on fundamentals but on paterns and indicators. I highly recommend his book.
