BAROMETER

barometer@atheron:~$

// Market readings, made by us

Weather for the market.

Volatility ahead. Dollars on chain.

Atheron Barometer is one engine with two feeds: a forecast of how much crypto prices may move over the next 30 days, and how many dollar stablecoins exist on each chain. Every number is calculated by us, from data we own or read straight from the chains.

// How it works

From raw data to a reading

No third-party index sits in the middle. We collect, calculate and publish it ourselves.

  1. 1

    Collect

    One-minute prices from our own history, and supply from the token contracts.

  2. 2

    Calculate

    A published method, the same way every minute, with its version on every reading.

  3. 3

    Publish

    A new reading every minute, with hourly and daily history kept from day one.

  4. 4

    Use it

    On this site, or in your own tools through the Atheron developer portal.

// Why Barometer

Numbers you can trace

Market data is only worth building on if you know where it came from.

Our own data

Built from our own price history and from the chains themselves, not resold from someone else's feed.

Open method

Every step is written down on the method page, down to the model's current weights.

Versioned

Each reading names the method version that made it, so stored numbers keep their meaning.

Honest limits

It measures and forecasts. It never tells you which way to trade.

// For developers
