I tried at one point to do it with Ninjatrader. The programming skills for the trading software is not complicated. What is complicated is tweaking it so it will make money, there are tons of indicators out there and many people have tried this with neural networks and the like. A lot of effort is put into it. I personally thought there were smarter people than me who barely had an edge. I honestly didn't think it was within the grasp of a single programmer nowadays, but this author has proved me wrong. He of course has much more sophisticated algorithms than what I was attempting.
