Where pullbacks have ended and rallies have stalled
A trend channel is two parallel lines drawn around a trend: the trend line through its swing lows (in an uptrend) or swing highs (in a downtrend), and a parallel channel line opposite. A bullish reversal at an up channel’s trend line is a pullback ending with the trend; a close through the trend line ends the channel.
Trends rarely move in a straight line. They move in waves: a push, a pullback, another push. The turning points of those waves are called swings: a swing high is a peak where a rally turned down, and a swing low is a trough where a pullback turned up.
In a steady trend, the swings often line up. A trend channel is two parallel lines drawn around them, one along the lows and one along the highs. It answers one question:
Where in the trend is price right now?
Near the lower line of an up channel, price is at the end of a pullback, where buyers have stepped in before. Near the upper line, it is at the end of a rally, where buyers have run out before. A candlestick pattern means something different at each.
The two lines have different jobs, and different names:
| Line | In an up channel | In a down channel |
|---|---|---|
| Trend line | Through the swing lows, below price: where pullbacks have ended | Through the swing highs, above price: where bounces have ended |
| Channel line | Parallel, through the swing highs: where rallies have stalled | Parallel, through the swing lows: where declines have stalled |
The trend line runs along the swings the trend is built on. In an uptrend that is under price, so it acts as support: a price area where buying has stopped declines before. In a downtrend it is over price, so it acts as resistance: an area where selling has stopped rallies before.
The channel line (also called the return line) sits on the opposite side. In a down channel, it is the lower line. That trips up many readers: in a falling market, the line under price is the channel line, not the trend line.
In an uptrend, connect two swing lows, the second higher than the first, and extend the line to the right. In a downtrend, connect two swing highs, the second lower than the first.
Draw a parallel line through the highest swing high since the first low (in a downtrend, the lowest swing low since the first high). That is the channel line.
Wicks or closes? Practitioners disagree. Lines through the wicks capture every extreme; lines through the closes ignore brief spikes. Pick one method and use it every time. What matters more is consistency, and judging a break by the close, as covered below.
In the figure, swing lows 1 and 2 set the trend line, and the channel line is its copy through the rallies’ peaks. The third pullback ends in a Hammer right on the trend line: price is back at the line, and a reversal candle shows buyers stepping in.
A channel tells you three things.
1. The direction and the pace. The slope of the lines is the trend’s speed. A steep channel is a fast trend; a shallow one is a slow grind. The steeper the trend line, the sooner an ordinary pullback reaches and breaks it, and traders often redraw a broken steep line as a slower channel.
2. Where pullbacks have ended. In an up channel, the trend line is where buyers have stepped in. The closer a pullback gets to it, the closer price is to support, and the less room there is to a sensible stop just below it.
3. Where rallies have stalled. The channel line is where earlier rallies ran out. Many traders take profits there, so it is a natural target, not a place to start buying.
Watch the rallies, not just the lows. When a rally stops well short of the channel line, buyers are weaker than before. It is an early warning, often before the trend line breaks. In the figure, the rally after the Hammer falls short, and a few days later price closes below the trend line.
A candlestick pattern tells you when buyers or sellers reacted. The channel tells you where in the trend that happened, and the same bullish candle reads very differently at each line:
| Bullish reversal candle at… | What it is | Where it can go |
|---|---|---|
| An up channel’s trend line | A pullback ending with the trend: the classic case | Up to the channel line, which rises each day |
| A down channel’s channel line | A bounce at the decline’s outer edge, against the trend | Up to the trend line, resistance that falls each day |
| The middle of either | A candle with no line behind it | No line nearby for a stop or a target |
For example, a Hammer on an up channel’s trend line: buyers reject lower prices at the line the trend’s earlier lows set, with the trend behind them and the channel line as a natural target. A stop just under the trend line keeps the risk small.
Now take a Bullish Engulfing at a down channel’s lower line. Sellers have stretched the decline as far as they did before, and buyers are pushing back. It can work, but it is a trade against the trend, and its target, the down channel’s trend line, falls every day the bounce takes, while an up channel’s target rises. Only a close through that trend line, not just a bounce toward it, would end the down channel.
On 42Fibonacci, the daily chart of a bullish reversal draws its current channel (or trading range) when it finds one, and a Reversal Setups result shows a Near trend line or Near channel line chip when the pattern formed at the up channel’s trend line or the down channel’s lower line.
Channels end. How they end tells you what changed:
A close through the trend line means the swings no longer hold. In an up channel, a close below the trend line says pullbacks have stopped ending where they used to. The trend may be over, or it may be shifting into a slower one. Either way, the channel you drew no longer describes the market.
A close through the channel line is usually read as the trend speeding up: buyers pushing harder than before, in an up channel. But a push well beyond the channel line can also be a last, exhausted burst. A quick close back inside the channel is the warning sign.
It is drawn, not measured. Two traders can pick different swings and draw different channels on the same chart. A channel is a reading of the swings, not a fact about the stock.
It describes the past. A channel shows where swings turned before. It says nothing about how long the trend lasts.
It is rarely exact. Real trends drift. Lines need redrawing as new swings form, and price often overshoots or falls short of a line by a little. Treat each line as a zone, not a wall.
It needs a trend. When price moves sideways, the lines go flat and the channel becomes a trading range: a flat floor (support) and ceiling (resistance), read differently (see Candlesticks + Trading Ranges).
A stock has climbed in a neat up channel for three months. It pulls back to the trend line again and prints a Hammer. A trader says: 'Hammer on the trend line, trend intact. I'll buy and set my target well above the channel line, since the trend is so strong.'
What's wrong with the plan?
The entry is sound; the target isn't. The channel line is where every earlier rally in this channel ran out, so it is where profit-taking is most likely, not a level to aim past. A sensible plan targets the channel line, with a stop just under the trend line. If price later closes and holds above the channel line, the trend may have sped up and the plan can be revisited then. And if the next rally stops well short of the channel line, that is the warning to tighten up.
| Mistake | Instead |
|---|---|
| Buying because price reached the line Price reached the trend line, so I’m buying. | The line says where to look; the candle says buyers actually showed up. Wait for a reversal candle at the line. |
| Mixing up the two lines in a downtrend The line under price is the trend line, so this is support with the trend. | In a down channel, the trend line is the upper line. The lower line is the channel line, and a bounce from it goes against the trend. |
| Calling a break on a wick Price spiked below the trend line. The channel is broken. | Wait for the close. Wicks through a line that close back inside are common, and can mark the low of the pullback. |
| Forcing a channel onto the chart If I draw from this wick to that body, it almost fits. | A channel should be obvious. If you have to bend the rules to make the lines fit the swings, the swings aren’t lining up, and there is no channel to trade. |
Two parallel lines drawn around a trend. The trend line runs through the swings that define the trend (the swing lows in an uptrend, the swing highs in a downtrend), and the channel line is its parallel copy on the other side. Price tends to swing between them while the trend lasts.
In an uptrend, connect two swing lows, the second higher than the first, and extend the line. Then draw a parallel line through the highest swing high since the first low. In a downtrend, connect two swing highs, the second lower than the first, and draw the parallel through the lowest swing low since the first high.
The trend line runs along the swings the trend is built on: under price in an uptrend, where it acts as support, and over price in a downtrend, where it acts as resistance. The channel line, also called the return line, is its parallel on the other side, where moves in the trend’s direction have tended to stall. So in a down channel, the lower line is the channel line.
Either, as long as you are consistent; traders are split on it. Wick lines respect every extreme, close lines filter out spikes. Whichever you draw, judge a break on the close: a wick through the line that closes back inside is not a break.
It depends on which line. A close through the trend line means the swings no longer hold, so the trend may be ending or slowing. A close through the channel line is usually read as the trend speeding up, though a push far beyond it can also be a last, exhausted burst. Some breaks fail and price returns inside the channel.
Buyers ran out sooner than in earlier rallies. That is an early warning that the trend is losing strength, and it often comes before the trend line itself breaks.
It is a trade against the trend. A bullish candle at a down channel’s lower line, the channel line, can produce a bounce, but its target, the down channel’s trend line above, is resistance that falls every day the bounce takes. A bullish candle at an up channel’s trend line has the trend on its side.
A channel slopes up or down with the trend; a trading range is flat, with price moving sideways between a horizontal floor and ceiling. When a channel’s lines flatten out, it has become a range, which is read differently.
A channel doesn’t tell you to buy. It tells you where in the trend a candle formed.
So when a bullish candlestick pattern prints, ask one question: “Which line is it at?” The table above gives the reading for each. If the answer is neither, the channel has nothing to add.
