Successful trading is all about balance. We must delicately balance a great many things in order to move freely in the world of trading. We must balance good news with bad news that is often issued simultaneously. We have to balance opposing views from analysts, conflicting signals from technical indicators, and dueling emotions from the depths of our soul. It's all about balance, and when it comes to the past, it is no different. For a trader, there is no doubt that the past is important. In one sense, it serves as our greatest teacher and our "mirror, mirror on the wall" that will always tell us the truth about ourselves. But in another sense, it can serve as our archenemy, one that can ruin our future in a heartbeat. Simply put, carrying too much of the past with us can be damaging. This is where the balance comes in. We can't place so much emphasis on the past that we allow it to spill over and taint our tomorrows. The past should only serve as a window into what was, not necessarily as a window into what will be. It should only be utilized as a tool that helps us tighten our belts, so to speak. But once those belts have been tightened, the tool should be put down, as it has no more usefulness. Traders must learn to drop the past, each time they enter into a new play. It has no place when dealing with the myriad factors in the present. Leave the baggage at home. During the day, we have to travel light.
