"How to draw a trendline" is one of the first things people learn when they study technical analysis. Typically, they quickly move on to more advanced topics and too often discard this simplest of all technical tools. Yet you’d be amazed at the value a simple line can offer when you analyze a market. As Jeffrey Kennedy, Elliott Wave International’s Chief Commodity Analyst, puts it: “A trendline represents the psychology of the market, specifically, the psychology between the bulls and the bears. If the trendline slopes upward, the bulls are in control. If the trendline slopes downward, the bears are in control. Moreover, the actual angle or slope of a trendline can determine whether or not the market is extremely optimistic or extremely pessimistic.” When a market is in a correction, you can draw a trendline and then draw a parallel line: in turn, these two parallel lines can create a channel that often "contains" the corrective price action. When price breaks out of this channel, there’s a good chance the correction is over and the main trend has resumed.
