Bitcoin weekly close: $77,263, inside the range

The week, from open to close

Bitcoin traded between a weekly low of $76,047 and a high of $79,890, and finished -1.5% from Monday's open. The number that settles the range is the close, and this week the close was $77,263.

Measured against the centre of the projected band, that landed +1.7% away. The verdict: inside the band.

Last week, same series: Bitcoin weekly close: $79,661, inside the range. That range is already settled and published, hit or miss.

The range comes out of a four-model engine, reweighted every week against the real record. How it is calculated, step by step.

The distance between the high and the low

Between the weekly low of $76,047 and the high of $79,890 there is 5.1% of ground, and the close ended 3.3% below the top of that span. The drawdown from the week's high is the number that tends to be felt rather than read.

Ranges are resolved on the close, not on the wick, and the two can tell very different stories. A week can spend days outside the band and still settle inside it, which is why the log records one number and not the most dramatic one available.

Frozen in advance, on purpose

Set the price aside for a moment. This range was emitted on September 8, 2026 and resolves against the weekly close of September 13, 2026. Those two dates are not decoration. They are what separates a forecast from a comment, because once the first one passes the number cannot be edited.

Almost nobody in this corner of the internet publishes their errors. That is not a moral failing, it is an incentive: an unmarked forecast is always right in hindsight. The full record, including the ranges that missed, is public and dated, and it can be read as data rather than taken on trust.

The track record this range joins

9 of the 11 projected weekly ranges published so far resolved inside the band. Every one of them was frozen before its week, and every result went up afterwards, including the ones that went wrong.

There is a trap in that number worth naming. A band that contains the close every single time is not a good model, it is a wide one. The published band is the middle half of the distribution, so a properly calibrated engine should land inside about half the time. A hit rate far above that means the bands are wider than they should be, which is a miscalibration too, just the flattering kind.

Reading volatility off the range itself

Context first, verdict after. The band is 5.8% wide between its edges. That single figure is the model stating, in advance, how much weekly movement it considered ordinary for Bitcoin right now. Wider bands mean the engine sees a jumpier market; narrower ones mean it is willing to commit.

It is a more useful reading than it looks, because it is the part of a forecast that people usually skip. A narrow band that holds is a real result. A wide band that holds proves very little, and the width is published precisely so nobody has to take the hit rate at face value.

The next number is already live

Now the part most readers skip. The next projected range is drawn over the live Bitcoin chart in the app, alongside the dated zones for the longer horizons, and it is recalculated on the server every day so that every visitor sees the same numbers. Nothing here is computed in your browser and nothing is personalised.

None of this is investment advice. It is one statistical model keeping its numbers where anybody can check them, including the weeks it gets wrong.
