Your judgment will become poorer from the very time when you decide that you know more about the market than the market is telling you. From that moment your results will be unsatisfactory, for in this trading business the tape is the boss. You must learn to obey its orders, doing exactly what it tells you. When you can accomplish this, you are on the high road to success in your stock trading.
