SOL Oracle Index

Solana down 15.1% over 28 days · 7-day 80% range $93.67–$108.80

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

Days without a forecast since the record began: Oct 10, 2026, Oct 11, 2026. The machine that runs the model was off; since Oct 24, 2026 the daily job runs the model itself if the morning run was missed. Gaps are shown, never filled in.

1 · 28-day trend

Solana is -15.09% 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 Solana 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 far ahead	Closes on	5th	10th	25th	Median	75th	90th	95th
1 day	Oct 28, 2026	$97.35	$98.13	$99.46	$100.95	$102.46	$103.85	$104.68
7 days	Nov 3, 2026	$91.70	$93.67	$97.05	$100.95	$105.01	$108.80	$111.13

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 Solana closes between $86.46 and $117.87 on Nov 26, 2026. Today it is at $100.95, 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 Solana, 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 6. Price: Binance, 00:00 UTC.

4 · Scorecard

Skill vs. history

0.20

Our chances had 20% less error than chances taken only from Solana's history. 0 means no better than history, 1 means perfect. This is the skill score; the raw Brier scores are below.

48 probabilities from 12 forecasts at 7 days. Too few to judge: we want at least 90 forecasts. The four levels of one day share one outcome and 7-day forecasts overlap, so treat this as about 12 independent readings, not 48.

Each day the index publishes chances like "20.2% that Solana closes above $106.00 in 7 days". The Brier score is the average squared distance between that chance and what happened (1 if it closed above, 0 if not): 0 is perfect, lower is better. We compare it with the same score for a reader who only knows history: how often Solana has ended above that level over the same number of days in its history, counting only days before the forecast. The 1-day chances are left out: they are almost always near 0% or 100%, and would flatter the score.

Horizon	Probabilities graded	Brier, ours	Brier, history	Skill
7 days	48	0.103	0.128	0.20

Re-grading random subsets of the forecasts gives a range of 0.04 to 0.46. Treat it as too narrow while the record is short: forecasts made a day apart overlap and share the same market.

Do the chances mean what they say?

When we said	Cases	Average chance said	How often it happened
under 20%	12	10%	0%
20–40%	12	26%	0%
60–80%	12	75%	75%
80% or more	12	92%	83%

If the chances are honest, the last two columns match once there are enough cases.

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.

Horizon	Graded	Inside 80% range	Inside 50% range	Average error
1 day	18	78% target 80%	72% target 50%	0.54%
7 days	12	83% target 80%	75% target 50%	1.30%
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 6, 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.

Horizon	Model	Graded	Inside 80% range	Average error
1 day	M0	18	83%	0.53%
1 day	M1 (official)	18	78%	0.54%
1 day	M3	18	89%	0.55%
7 days	M0	12	83%	1.33%
7 days	M1 (official)	12	83%	1.30%
7 days	M3	12	100%	1.32%

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

Over the last 30 days Solana's price has moved about 1.9% a day (36% annualised), calmer than 99% of days since September 2020. Level 1 of 100 means only 1% 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 2,238 days since 2020-09-10. 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 SOL 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 Solana 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.
