How I made $500k with machine learning and high frequency trading
This is just glorified gambling.  I am not sure what special insight or advantage he had, other than his own model.  Every trader has a model.It could have easily been called "how i lost 500k with machine learning".  Like gambling, it's easy to manipulate statistics to show that you did well in some period of time.I worked for a large investment bank about 10 years ago, writing trading programs for quant traders who were market makers.  The quants called guys like him "retail" investors and they gleefully picked off all those trades.  It's how they made all their money.So, everyone else, beware of making this a case study in how to make lots of money really fast.  You are more likely to lose money.
