What it shows
The highest high and lowest low of the last N candles, and their middle.
How to read it
A new high above the upper line is a breakout of the last N candles' range.
How it's calculated
The upper line is the highest high of the last 20 candles, the lower line the lowest low, and the middle line sits halfway between them. The lines only move when a new high or low enters the window or an old one drops out, which gives the channel its stepped look.
What it can't tell you
A new 20-candle high is a fact about the last 20 candles only. On a short timeframe that can be a small move.

FAQ
What does 'a new 20-candle high' in the table mean?
The current 1h candle has traded at or above the highest high of the previous 20 hours, so it touches the upper line.
Why is the middle line useful?
It is the midpoint of the recent range, so it shows at a glance whether price trades in the upper or the lower half.
Can I use a longer channel?
Yes, the length goes from 2 to 300 candles.
