Note: This is not my view of Price Action, but it's a good way of looking at it nonetheless, especially if you're new to PA.
Chart analysis doesn't attempt to forecast or predict prices. It is more about watching the price action and reacting to what happens. The trend followers, for example, work with reactive analysis, following the price wherever it goes rather than to think about where it might be going next. When trading with the trend, you can focus on just the moves the market makes and not get distracted by trying to figure out the duration and direction of the market's next moves. Simply put, you never get in right at the bottom, and you never get out right at the top. You don't allow yourself to fall into the trap of thinking, "Surely, this gotta be the absolute top or bottom." Also, with price analysis, you might find that you do not need to trade every day. Instead, you'd rather wait for the proper trading conditions to present themselves before you take advantage of them. Another thing is that you have no goals in terms of performance. Some traders use strategies that mandate them to make a set amount of money per day. For the PA trader, they know there's a chance the market won't offer them a fixed movement for the day--if at all. They take whatever the market offers them, no more and no less. They're not worried about predicting trends and are more interested in following the current trend.
