** Quick Chart Lesson: Drawing Trendlines **
Along with support and resistance levels, trendlines are one of the most basic, yet important aspect of technical analysis.
Trendlines main uses are predicting future support/resistance areas, or alerting us as to "when" a breakout (or breakdown) has occured... meaning, if the trendline is telling us a resistance level should be at point X, but when the price reaches point X, it goes right through, that would be known as a "breakout".
Trendlines are very easy to draw, but you must first understand support/resistances. The easiest way to think about drawing them is a "connect-the-dot" puzzle. Your dots are going to be the points of support/resistance, and when you connect the dots, BOOOOOM, you got yourself a trendline :)
