Read the Supply and Demand Index

The Supply and Demand Index answers one question: where does this price sit inside its own history?

Zero means deep demand, the discounted end of the range, where long-term accumulation has historically concentrated. One hundred means deep supply, historically overheated. Bitcoin is free for everyone, no account needed.

The zones have prices now

A shaded band telling you a coin looks cheap is nearly useless. So the chart names the numbers.

Under the price line you will see two ranges spelled out, something like a demand zone running from the year's low up to a specific dollar figure, and a supply zone from another figure up to the year's high. Those are quartiles of the range, and the year's low is the floor of one while the year's high is the ceiling of the other.

That turns "this looks lowish" into a number you can actually act on.

Four windows, and they will disagree

You can read the same coin over four hours, thirty days, ninety days or one year. Expect them to contradict each other, and pay attention when they do.

A coin can sit at the very top of its thirty-day range while sitting a fifth of the way up its one-year range. Both readings are correct. They just measure different questions, and which one is "right" depends entirely on where you decide the window ends.

Short windows move fast and reverse often. They will tell you something is overheated the week before it doubles. When the four-hour and one-year readings are far apart, the panel says so, because the disagreement is more informative than either number alone.

The one-year reading is the one the index is built around. It is the score on every card and every report.

What it does not do

It does not predict. It cannot tell you what happens next, and anybody selling you an indicator that claims otherwise is selling you something.

It also says nothing about whether an asset is permissible. That is a separate question with its own page.

In one line: it tells you whether today is ordinary or unusual for that coin, priced in dollars, across four windows that will not always agree.
