Anyone who's interested in buying a profitable EA, here is a question you want to ask before you swipe your credit card: Would anyone sell you the goose that lays golden eggs? Maybe the eggs, but never the goose.
Do your own work, put in a few years in this business and you have greater chance of seeing the light. Try read a lot. A LOT. Read the news, read the industry journals, read The Economists, read the well-known trading books, read the Fed reports, read the NFP numbers, read the prices, read everything you can get your hands on. And maybe then you will have this bulb lighting up in your head.
