Dogecoin down 17.2% over 28 days · 7-day 80% range $0.0710–$0.0852

Forecast date Oct 27, 2026 · updated Oct 27, 2026 (UTC) · model M1 (EWMA volatility), version M1.0

1 · 28-day trend

Dogecoin is -17.23% over the last 28 days.

A fact about the price, not a reading of the index: the trend rule was only tested on Bitcoin, so it is only shown there. It says nothing about where the price goes next.

2 · Expected range

Where Dogecoin is likely to close (Binance, 00:00 UTC) at each horizon. The center is today's price: this index says how wide the outcomes are, not which way they go.

A hundred ways the next 30 days could go

Each line is one path the model finds plausible. None of them is a prediction. The shaded bands hold 50% and 80% of where they end.

50% range   80% range   90% (5th–95th percentile). Center = today's price: the model makes no directional call.
Each path moves by a random percentage every day, sized so the paths end spread the way the model's 30-day range says. Price: Binance close, 00:00 UTC.

How to read the columns: 9 times in 10 the close should land above the "10th" price, and 9 times in 10 below the "90th". Between those two is the 80% range quoted on the rest of the site; the median is the middle, which here is always the last close.

3 · Old forecasts don't disappear

On Oct 27, 2026 the index said: there is an 80% chance Dogecoin closes between $0.0643 and $0.0940 on Nov 26, 2026. Today it is at $0.0778, inside that range, with 30 days to go.

Tomorrow there will be a new forecast, but it does not erase this one. Every forecast stays here until its own date arrives. On that day we check the price: inside the range is a hit, outside is a miss, and both go to the scorecard below. The proof page shows each one was stamped into Bitcoin before its date (for Dogecoin, since Oct 24, 2026).

Each fan is one day's forecast. The black line is the real price.

Every day the index draws a range for 30 days out. Here they all are, from the day each was made to the day it gets checked. The shaded one is the newest. If the black line ends inside a fan on that fan's last day, it was a hit.

The fans widen because the further ahead you look, the less anyone can know. They show how wide the outcomes are, not which way the price goes. Only the price on each forecast's last day is graded. The first one gets checked on Nov 23. Price: Binance, 00:00 UTC.

4 · Scorecard

Skill vs. history

Nothing graded yet. The first 7- and 30-day probabilities are graded when their dates arrive.

Resolved questions

The latest graded questions. A red row means the outcome went against the side our chance leaned to; that happens about as often as the chances say it should, if they are honest.

Ranges

Every forecast is written before the outcome is known and graded automatically against the Binance close. A well-calibrated 80% range should contain about 80% of outcomes. Small samples swing a lot; the counts are shown so you can judge.

HorizonGradedInside 80% rangeInside 50% rangeAverage error
1 day 3 100% target 80% 100% target 50% 0.39%
7 days 0 — target 80% — target 50% —
30 days 0 — target 80% — target 50% —

Average error is the pinball loss, the standard grade for percentile forecasts: it adds up how far the real close fell from each published percentile, as a share of the price. Lower is better.

Graded 30-day forecasts

No 30-day forecast has reached its date yet; the first one is checked on Nov 23, 2026. Until then you can follow them above.

The tables show the last ten graded forecasts per horizon; the counts above include all of them. We will not claim accuracy before roughly 90 days of record.

The models in the shadow

Four models run every day; M1 is the official one. The others are graded the same way and shown here so the comparison is public. One of them can replace M1 only by the rule in the methodology, never before Jan 15, 2027. M0 is the plain baseline: the last 30 days' realized volatility.

HorizonModelGradedInside 80% rangeAverage error
1 dayM03100%0.34%
1 dayM1 (official)3100%0.39%
1 dayM33100%0.38%

M0: volatility of the last 30 days. M1: exponentially weighted volatility (the official model). M2: the option market's implied volatility (Deribit DVOL; Bitcoin and Ethereum only). M3: the last year's actual moves, no distribution assumed. Full definitions and the test that chose M1 are on the backtest page.

5 · Volatility level

Volatility level
0 25 50 75 100 11 of 100 Very calm Calm Turbulent
Over the last 30 days Dogecoin's price has moved about 2.3% a day (43.5% annualised), calmer than 89% of days since August 2019. Level 11 of 100 means only 11% of days were calmer. It measures how much the price moves, not which way.

The level is the percentile of today's 30-day realized volatility (standard deviation of daily log returns, annualized) among all 2,641 days since 2019-08-04. 0 is the calmest month on record, 100 the most turbulent. It is a measurement, not a forecast: a calm month says nothing about which way the next move goes.

What this is — and isn't

The DOGE Oracle Index is the daily output of a set of statistical models that are published before the outcome is known and graded publicly afterward, including misses. It does not predict whether Dogecoin will go up or down: none of the return signals we tested held up out of sample, and this index makes no directional call. The expected range describes uncertainty, not a target. Past performance does not guarantee future results. Nothing here is a recommendation to buy, sell or hold any asset, and nothing is tailored to your situation. The author may hold crypto assets, including BTC.
