Ask the traders who pyramiding up or down while in winning positions or losing positions and read Market Wizards how these guys become rich. It was pyramiding while their positions were winning, not losing. Evidence is proven everyday that Martingale don't work. I think the Dot Bomb Bubble years were an extreme major example but no one can last forever fighting the market when proven wrong (even the Bank of England couldn't do it vs Market and Soros).
