Trendlines - A trendline is a line that we can draw through a series of highs or lows. These can be horizontal, or sloping up or down. Trendlines are used to pick what are called support and resistance lines. Drawing a trend line is like doing a join the dots picture. The more points you can draw through, the better the trend line.
