Upward trend lines are used when the price is consistently moving upwards (an upward trend). Upward trend lines are drawn from a low point on the left to a high point on the right (/), and are drawn below the price bars, so that it appears as though the trend line is holding the prices up (known as support). Trend lines will be easy to fit to the prices bars if the current price movement is smooth, but trend lines will not fit as well if the price movement is not smooth.
Trend Lines can be defined as both a mathematical formulae (which is useful for automated trend line trading), and as a visual pattern on a price chart (which can be easily recognized by human traders). This tutorial will cover drawing trend lines visually, as this is the most useful method for beginning day traders.
