AXiV — Bitcoin and Ethereum volatility index

AXiV is realized volatility over the last 24 hours: the typical size of price moves, expressed per day. 2% means the coin usually travels about 2% of its price in a day. A quiet coin sits around 2%, a violent one at 15%.

Once enough history builds up, the week and the month appear next to it — a smoother background for the jumpy daily value.

The colour depends only on the number, and the scale is the same for every coin: green — under 3% a day, no colour — 3 to 6%, orange — 6 to 10%, red — 10% and more. Bitcoin is usually green; small coins are often orange or red.

Whether today is a lot for this particular coin, the chart shows: the line against its own past two weeks, three months or a year. The number of days observed is written under it.

Every five minutes AxiPivot records the price. Log returns between neighbouring snapshots → standard deviation → scaled by the square root of the number of steps in a day (√288 for five-minute data). That gives daily volatility in percent; annualised is ×√365.

Gaps are not stitched: a jump across a missed run is dropped, and a price older than 15 minutes never enters the series. A stalled data feed never reads as a calm market.

BitMEX computed .BVOL24H and .BVOL7D the same way, and many traders watched them on TradingView. BitMEX closed in September 2026, and the quotes stopped with it. AXiV uses the same formula and adds what an index built for a futures contract could not carry: context — the coin's own history and a comparison with bitcoin — and one yardstick for every coin in the pool, not only bitcoin.

Deribit's DVOL is a different thing: implied volatility, the move the options market expects. AXiV shows what the price actually did.

AXiV is not a forecast or a signal and says nothing about direction — only how much room to expect. For analysis, not for trading.

In the app AXiV is on every coin page, with its chart next to bitcoin's, and in the market table as “× BTC” — how many times jumpier a coin is than bitcoin right now.
