Price channel
Also called: Trend channel, Ascending channel, Descending channel, Horizontal channel, Parallel channel, Kanal formasyonu
A channel is price moving between two parallel lines at the same slope; its edges show where pullbacks in the trend tend to end.

What is a price channel?
Trends don't move in straight lines; they move in waves. In a falling market each rally ends below the last one (a lower high, LH) and each drop goes below the last one (a lower low, LL). Join the highs with one line, draw a parallel through the lows, and you have a channel.
It tells you two things: how fast the trend is moving and where pullbacks tend to stop. In a descending channel the upper edge is where rallies run into sellers. The lower edge is where selling tires and profit-taking comes in.
A horizontal channel is really a range: price bouncing between support and resistance. Trade the edges, wait in the middle works at its cleanest here.
How do you draw a trend channel?
Find the structure first, then the line. A descending channel needs at least two lower highs and two lower lows. Join the two highs, copy the line and move it to the low in between. If price touches an edge a third time and turns, the market sees the channel too.
Wicks or bodies? Either works as long as you're consistent. If price pokes a wick or two past the line, that's not a break. A channel is a zone, not a laser-cut border.
In a descending channel a short idea makes sense when price turns back from a supply zone near the upper edge, usually with a rejection wick or an engulfing candle. The stop goes above the last lower high: if price closes above it, the LH structure is broken and the idea is invalid.
An example: EUR/USD on H1, last high 1.0870, a pullback rejected at 1.0862, and you're looking to sell at 1.0855. Stop around 1.0875, so 1R is about 20 pips. If the lower edge sits at 1.0815, you have 2R of room. If it sat at 1.0840, the same trade would risk 1R for half an R.
Try it on a chart
No channel lines are drawn on this chart; you get a descending structure and a rally against it. Draw the channel in your head: join the recent highs and see where the rally sits relative to that upper edge and the supply zone.
The downtrend structure holds; price corrected higher and turned back from the supply zone. What do you do?
No sign-up needed. Make your call; when the chart opens you'll see why.
Where channel traders go wrong
Trading the middle comes first. With price halfway between the edges there's no nearby structure for a stop and not enough room for a target. Wait for an edge.
Second is fading the trend. Buying the lower edge of a descending channel looks sensible on paper, but you're against the trend with a short target. That's the trade that keeps getting stopped. The edge in the trend's direction gives cleaner setups.
Third is bending the line to fit. Nudge it a little with every new candle and you end up with a drawing that explains the past, not a channel. If a channel built on two or three touches breaks, treat it as broken and draw a new one once structure is clear.
When does a channel stop working?
When the structure breaks. If price closes above the last lower high in a descending channel, the channel is done. Selling the upper edge after that means believing in a trend that no longer exists.
Channels narrow or widen over time. If highs and lows aren't moving at the same pace, you're not looking at a parallel channel but a wedge or an expanding structure, and the read changes.
News and fast markets blow through channel edges easily. A sharp candle can slice through the lower edge; a headline can tear through the upper one. A channel maps a calm trend; when volatility explodes, trust structure rather than the map.
Timeframe changes the picture too. A clean descending channel on H1 can be an ordinary pullback inside a daily uptrend. When the bigger picture points the other way, moves inside the small channel run out sooner, so keep targets modest.
Frequently asked questions
Do you buy in an ascending or a descending channel?
The channel doesn't give you a direction, only a slope. In an ascending channel the trend is up, so the logical trade is buying near the lower edge with the stop below the last higher low. In a descending channel it's the reverse: selling near the upper edge, stop above the last lower high. Trading the opposite edge is possible, but the target is short and failure more likely.
When is a channel breakout valid?
When a candle body closes outside the channel edge, and especially when price also clears the last structure point. A wick slightly beyond the upper line of a descending channel is not a break. A close above the last lower high, though, breaks both the channel and the LH structure. Many traders also wait for a retest: a return to the broken edge that holds.
Should a channel be drawn from wicks or bodies?
Both are used; consistency matters more than the choice. Wick-based channels show the extremes, body-based ones show where closes stop. Either way, a wick or two over the line is normal. Treat the edge as a zone a few pips wide rather than a single price, and put your stop beyond the last structure point, not beyond the line.
