I'll tell you a quick story. After an unsucessful trading experience on the CBOT floor, I went to work for a woman who was hawking trading indicators, she had written a book, gave seminars, etc..., the whole ten yards. The reason she no longer worked in the hedging department of her former large employer was that she had "made too much money and made her bosses look bad." I sold this ridiculous software for six months before bailing out. She could not trade her way out of a wet paper bag yet retail futures traders beat a path to her door. Our relationship didn't end well, I moved on to better things (i think), she is still in business, roping in suckers.
