What it is
A channel is a stretch in which price moves between two parallel lines: the lows rest on the lower one and the highs on the upper one. If the lines rise, it is a rising channel; if they fall, a falling one; if they run sideways, a sideways channel or range.
The textbook suggests two things: trade the bounce (buy at the lower line, sell at the upper one, preferably with the channel's trend) and, if a line breaks, follow the breakout. We measured it.
How we detect it
With fixed rules and without looking at the future, the same as the app's tool:
- Swings: the last 2 to 4 swing highs and lows of the previous 100 hours (each the extreme of the 3 candles on either side), with at least 2 of each.
- Lines: the best-fitting line through the highs and the one through the lows. They are parallel if their slopes differ by less than one average volatility (1 ATR) over the whole pattern. The channel is at least 3 ATR wide and 30 hours long, and no candle closes outside it.
- Type: if the midline rises more than 1.5 ATR, rising; if it falls, falling; otherwise, sideways.
- Touch: a candle reaches a line (within ¼ ATR) and closes inside. The textbook expects a bounce back inside.
- Breakout: the first candle that closes outside. The textbook expects it to carry on that way.
These rules produce few channels (about 200), so we repeated everything with a broader version (parallel within 1.5 ATR, from 20 hours) to see whether the conclusions change. We give both. The measure, as always: two bands at ±1.5 ATR from the signal close and which one price touches first within 48 hours, against chance in the same data.
Which side does it break?
| Rising and falling channels that broke | Cases | Against their trend |
|---|---|---|
| Main rules | 161 | 82.0% ±5.9 |
| Broader version | 284 | 79.6% ±4.7 |
It is the clearest result of the study: four in five trending channels ended up breaking against their trend. It makes sense: a rising channel forms while the rise lasts, and most often it ends when the rise runs out, not by accelerating. Knowing this changes how you read a channel: it is not a motorway, it is a stretch that ends at some point.
Bounces and breakouts
| Signal | Main rules | Broader version | Chance |
|---|---|---|---|
| Touch of a line | 50.5% ±7.1 (190) | 46.5% ±5.3 (346) | 50.0% |
| …with the channel's trend | 45.1% ±9.7 (102) | 42.7% ±7.3 (178) | 50.0% |
| …in a sideways channel | 55.9% ±12.7 (59) | 52.7% ±9.2 (112) | 49.9% |
| Breakout of a line | 49.0% ±6.8 (207) | 48.3% ±5.1 (364) | 50.0% |
| …against the channel's trend | 48.1% ±8.6 (132) | 48.0% ±6.5 (226) | 50.0% |
How to read it:
- Touching a line was not a bounce signal: in both versions, at chance or slightly below.
- The "textbook" bounce, with the trend, came in below 50% in both (45% and 43%), at the edge of the margin. It fits the above: if channels usually end by breaking through the trend line, buying right at that line is buying where they most often end.
- After the breakout there was no edge either: 48–49%. Knowing which side it will break does not tell you what price does next.
So what is a channel for: knowing where price sits within its range and where the stop goes (on the other side of the line), not guessing the next move. It is context you train, just like the RSI.
