BITCOIN AROON

What is Bitcoin Aroon?

Bitcoin Aroon measures the age of recent price extremes. Aroon Up tracks how many candles have passed since the highest high; Aroon Down does the same for the lowest low. It focuses on when those extremes occurred rather than how far price moved, making it a useful contrast to indicators based on returns or average-price gaps.The default period is 25. Maketo examines the current candle and the preceding 25, allowing an extreme to be between zero and 25 candles old. Each age becomes a 0–100 reading: a fresh extreme gives 100, while one 25 candles old gives 0. If an extreme is repeated, the most recent equal high or low is used.

A high Up line means a recent high

Aroon Up of 100 means the latest candle contains the window’s highest high, including a tie under Maketo’s most-recent rule. It does not say the price rose 100% or that its latest close is at that high. A candle can reach a high and finish well below it.

Read Down as the age of a low

High Aroon Down means the window’s lowest low occurred recently. A low Down reading means that low is older; it does not, by itself, prove price is rising. Comparing both lines shows which extreme is more recent and how far apart their ages are.

Use the difference without losing the two ages

The oscillator view subtracts Down from Up. Maketo labels a difference of +20 or more Rising, −20 or less Falling, and the space between Mixed. The same difference can come from two high lines or two low lines, so the separate-line view adds context that one difference cannot show.

How Aroon is calculated

Each line converts candles since the window extreme to a 0–100 reading. The oscillator subtracts Aroon Down from Aroon Up. The default window is 25 candles. The page is published on Aroon lines, period 25. 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

An invented 25-period example demonstrates the age calculation and its fixed steps. Suppose the most recent highest high occurred 5 candles ago and the most recent lowest low occurred 20 candles ago.Aroon Up = 100 × (25 − 5) ÷ 25 = 80. Aroon Down = 100 × (25 − 20) ÷ 25 = 20.The difference is 80 − 20 = +60. The high is considerably more recent than the low.If no new extreme appears on the next candle and both old extremes remain in the window, their ages become 6 and 21. Up becomes 76 and Down becomes 16. Both lines fall by four points, while their difference stays +60.Parallel declines in the two lines can simply mean both extremes are aging. The lower lines are not a measurement of falling Bitcoin prices.

Period and step size

With period 25, each extra candle of age changes a line by four points. With period 20, the step is five points. A smoother-looking range of values from a longer period does not add precision to the underlying high or low; it changes the age scale.

Window and ties

The current candle plus the previous 25 gives 26 observations for the default first reading. Equal highs or lows reset the age to their most recent occurrence. Platforms using another window length or tie rule can disagree even when they show the same nominal period.

Timeframe

A high five daily candles ago is five days old; on a weekly chart it is five weeks old. Candle highs and lows also change with aggregation. Changing from hourly to daily does more than relabel the same line’s time axis.

A tiny new high can reset the clock

A high one dollar above the previous extreme can produce the same Aroon Up value as a high thousands of dollars above it. Aroon describes recency, so compare the price chart or a return measure when magnitude matters.

An extreme can disappear without being exceeded

When an old highest high leaves the window, a lower but more recent high becomes the new reference. Aroon Up can jump even though no new high was set relative to the previous full window. Check the rolling window before attributing every jump to new price strength.

A wide candle can refresh both sides

One candle can reach both the window’s highest high and its lowest low. Both Aroon lines can then be 100 and their difference zero. That describes fresh extremes on both sides, not a quiet market.

Aroon compared with ADX and Directional Movement

ADX measures smoothed directional imbalance, while Aroon measures the age of extremes. A fresh high can lift Aroon Up without immediately raising ADX. A steady sequence of modest directional moves can raise ADX before a much older extreme is exceeded. Open Bitcoin ADX and Directional Movement.

Why do Aroon lines move in steps?

They count whole candles since an extreme. With the default 25-period setting, one candle corresponds to four points. The step pattern follows directly from that counting rule.

Does a falling Aroon Up line mean price is falling?

No. It means the current window’s highest high is older, unless the rolling window changed its reference. Price can still rise while remaining below that high.
