Technical Analysis VIII: Price Channels
A trending market can move between parallel support and resistance levels. A price channel between two parallel lines can often be drawn in a trending market. The key to a price channel is that the lines be parallel to each other. The value of the price channel in predicting the ongoing speed of a trend depends on the lines being parallel.

Unlike trend lines, which can be drawn on any chart with two relative lows or highs, price channels should not be forced on a chart where they are not quickly apparent. Once a trend line is established, create a duplicate parallel line on the chart. Then move it up to the relative highs above or down to the relative lows below the trend line. If two or more fit with the line, there may be a valid price channel. Otherwise, the market may simply be too volatile - even in the midst of a strong trend - to plot a channel.
Technical Analysis VII: Trading the Trend Lines
Only one of two things can happen when a price approaches support or resistance: the price can break through it, or it can bounce off and reverse direction. The same is of course true for trend lines.
1. Trading on a Pullback
If a chart is trending in a clear direction, and a trend line can be drawn connecting a series of relative highs or relative lows, trading opportunities exist when the price approaches the trend line. If the price bounces off the trend line and resumes the trend in the original direction, this can be an excellent opportunity to enter the market in the direction of the dominant trend. This is often referred to as buying on a pullback in an up trend or selling into strength in a downtrend.
Technical Analysis VI: Trend Lines
What are Trend lines?
Trend lines are lines drawn on the historical price levels that depict general direction of where the marking is heading, and provide indications of support or resistance.
Drawing trend lines is a highly subjective matter. The best test of whether a trend line is a valid one is usually whether it looks like a good line. In an up trend, a trend line should connect the relative low points on the chart. A line connecting the lows in a longer-term rally will be a support line that can provide a floor for partial retracements. The down trend line that connects the relative highs on the chart will similarly act as resistance to shorter moves back higher.
Technical Analysis V: Trending and Ranging Markets
In Trending Markets
The existence of a trend in any market depends on a series of relative highs and lows. Two consecutive relative highs, each above the previous relative high, and two relative lows above the previous low would be constitute a tentative up-trend. A third relative high would confirm the trend.
