Price Action: Trend Channels (Part 1)

Trend and Channel Concepts
Trends mean that price moves in one direction most of the time. All moves from the lower left to the upper right (or the opposite direction) are contained within a "channel." A channel is defined by two lines: the trendline at the bottom and the channel line at the top.
Drawing and Adjusting Trend Channels
The trendline connects a series of higher lows; the channel line can be drawn parallel to the trendline or directly connect the highs.
Trendlines are never perfect.
After the market breaks below the original trendline, a new trendline should be redrawn using the lower point.
The redrawn channel becomes flatter and wider, but this does not mean the trend has changed.
Structural Elements of a Bull Trend
A bull trend must continuously produce higher highs and higher lows.
The trend channel is contained by both the up trendline and the channel line.
The key is the "higher low" — it is more important than the "higher high" because traders use it to set their stop loss levels.
Traders typically place their stop loss below the most recent major swing low, which is the starting point of the current leg up.
Only after the market makes a new high or a strong bull breakout will traders consider raising their stop loss.
Sideways Transition and Bear Reversal
If the market breaks below a higher low, it may first transition into a trading range rather than directly reversing into a bear trend.
A true bear trend usually requires a double top structure or other reversal confirmation signals.
In a broad channel, each bear reversal attempt tends to fail. Bulls buy at the close of bear bars, and as long as the market keeps making higher lows, the trend is considered to continue.
Failure Probability of Bear Channel Breakouts
Approximately 75% of bear channel downside breakouts fail.
Price usually bounces back to the top of the channel or to the top of the most recent sell climax within five bars.
The first breakout is often a minor reversal, followed by a trading range or a bear flag, rather than a direct transition into a bull trend.
Trading Ranges Are Also Channels
If the price action is not particularly clear and the chart is in a trading range, it is essentially a horizontal channel.
Within a trading range, both bulls and bears have valid reasons to trade.
Bull Signals in a Bear Trend
In a bear trend, when the following signals appear for the first time, bears will sell, betting that the reversal attempt fails, creating opportunities for bulls to add to their positions:

The first strong bull bar
The first touch of the moving average
The first gap bar
Some bears are more conservative and will wait for reversal confirmation before acting.

Channel Breakouts and Transition Signals
Approximately 70% of channel breakouts — whether upward or downward — fail and reverse to the opposite side of the channel within five bars.
Traders watch channels to capture "transition signals." Channels have approximately a 75% probability of evolving into a trading range.
In a tight bull channel, traders only consider going long. Once price breaks below the channel, it is viewed as the early stage of a trading range, and short trades can be considered. However, on a higher time frame, this trading range is still a bull flag, so the dominant approach remains bullish.
Overlapping of Old and New Trends and Transitions
A new trend often begins before the old trend has ended.
Many people mistakenly believe that a bull trend suddenly turns into a bear trend; in reality, there is a transition process.
The seeds of the bear trend are often planted at the last swing point of the bull channel. The last pullback of the bull trend is the first pullback of the bear trend.
Reversal Signals at the End of a Bear Trend
When obvious buying pressure appears at the end of a bear trend, it often means the bear trend is about to end and a larger reversal is coming.
Variety of Channel Patterns
Parallel channel: the trendline and channel line are parallel.
Expanding triangle: highs and lows diverge, with boundaries spreading apart.
Converging triangle (wedge): highs and lows converge, with boundaries gradually narrowing.
Any area that can be bounded by two lines can be considered a channel, including horizontal trading ranges.
Patterns are never perfect; traders must be flexible in identifying imperfect channels.
Trading Strategies for Tight and Broad Bull Channels
Tight bull channel: pullbacks are minimal, lasting only one or two bars with a range less than twice the average bar size; the channel itself is a breakout, and traders should stay long.
Broad bull channel: pullbacks are deep and prolonged, often retracing more than 50% of the previous leg up; accompanied by upper shadows and bear bars; suitable for buying low, selling high, and taking quick profits.
