BITCOIN DONCHIAN CHANNELS

What is Bitcoin Donchian Channels?

Donchian Channels mark the highest high and lowest low in a chosen block of prior candles. Their middle line is halfway between those extremes. Their boundaries follow the observed extremes, while the middle gives those two extremes equal influence.Maketo’s default window is 20 candles, and the current candle is excluded from its own channel. The line shown beside a candle is calculated from the preceding 20 candles. This timing detail matters: it lets the current high or low cross a previously established boundary rather than moving the boundary to include itself immediately.

A flat boundary preserves an older extreme

The upper line stays unchanged while its highest high remains in the selected window and no newer candle exceeds it. A flat line therefore does not mean the market stopped moving. It means the same earlier high still defines that side of the channel.

A step can come from an observation leaving

The upper boundary can drop when an old high leaves the window, even if current price barely changes. The lower boundary can rise when an old low drops out. Channel narrowing can reflect the ageing of extremes as well as quieter recent trading.

Distinguish crossing the boundary from closing beyond it

A candle’s high above the preceding upper boundary establishes a new window high, but its close may finish back inside. Those are different observations. Maketo’s direction label instead compares the close with the middle and checks whether the middle has risen or fallen over five candles.

How Donchian Channels is calculated

The upper line is the maximum high of the previous 20 candles, the lower line their minimum low, and the center their midpoint. The page is published on Donchian channels, period 20. A period counts candles at the interval you choose, so the same setting covers a different stretch of time on a one-hour chart than on a daily one. How smoothing and missing candles are handled.

A calculation you can follow

For a small illustrative five-candle window, suppose the preceding highs are $101,000, $104,000, $103,000, $102,000 and $103,500. The lowest low across those candles is $97,000. The upper boundary for the next candle is $104,000, the largest of those highs.The lower boundary is $97,000. The middle is ($104,000 + $97,000) / 2 = $100,500.If the next candle reaches $105,000 but closes at $103,000, its high crossed the old boundary while its close remained below it.That $105,000 high enters the channel used for the following candle. It does not rewrite the boundary that was available before the move.The example separates a previously known level from the later price that tested it. Keeping this order prevents a chart from appearing to know an extreme before it happened.

Lookback period

The default is the preceding 20 selected candles. A longer window retains older highs and lows longer. It generally creates a wider or equal range when comparing windows ending at the same prior candle, but its middle can move in either direction.

Candle interval

Twenty daily candles and twenty hourly candles use different observed extremes. The intraday path disappears when prices are combined into daily candles, although each daily high and low preserve that day’s outermost prices.

Current-candle exclusion

One extra candle is needed beyond the lookback to display the first channel alongside a current observation. With period 20, the first plotted result accompanies the twenty-first candle in a complete run.

An extreme is not an average paid

The highest high could represent very little traded volume. Donchian gives it the same boundary-setting role whether a few BTC or many BTC traded there. The channel contains no information about the amount of activity at each price.

Changing windows can change the story

A close may be above a short window’s upper boundary but still inside a longer window. Both can be correct. State the period and candle interval when citing a new high, low or channel crossing so another reader can reproduce it.

Donchian Channels compared with Keltner Channels

Keltner Channels place a measured range around an average. Donchian uses observed extremes directly. A single isolated high can hold the Donchian upper line in place until it leaves the window, while its influence on a smoothed Keltner channel fades gradually. Open Bitcoin Keltner Channels.

Why is the current high sometimes above the upper channel?

The current candle is deliberately excluded from its own boundary. A high above that line exceeds the previous window’s maximum. The new high can affect the following candle’s channel.

Is the middle an average of closing prices?

No. It is the midpoint between the highest high and lowest low. Prices may have spent almost no time at that midpoint, and it can differ substantially from an average close.

Why did the upper line fall without a large price drop?

The earlier highest high may have aged out of the rolling window. The next-highest observation then becomes the boundary. That is a change in the reference window, not necessarily a sudden new fall.
