Updates

Bitcoin Accumulation Trend Score metrics added

Added Bitcoin Accumulation Trend Score (ATS), a 0–1 score of aggregate BTC accumulation across six address-balance cohorts, from <1 BTC to ≥10k BTC. The score combines accumulation strength with its trend and is available across 1D, 7D, 30D, and 60D analysis windows.

Added Bitcoin ATS by Address Cohort, which scores the same six cohorts separately and displays them as a heatmap. A cohort score rises when accumulation strengthens, distribution eases, or both. The heatmap shows whether accumulation is broadening across balance ranges or concentrating in a few cohorts.

Historical event markers on all charts

Added historical event markers to Drawing tools: Bitcoin halvings, market stress, adoption and market access, Bitcoin network events, and macroeconomic events. Each group draws vertical event lines on the current chart. In Chart cursor mode, hover over or tap a line to read its description.

You can now choose how the Metric Summary panel is displayed, switching between a compact and a detailed view.

Fixed chart autoscaling errors, Apple Pencil interaction issues, and incorrect drawing geometry when moving or resizing objects.

AVIV metrics and Supply Redistribution improvements

Added a new group of cointime valuation metrics: AVIV Ratio, AVIV-NUPL, True Market Mean, Active Market Cap, Vaulted Market Cap, Investor Cap, Active Supply, and Vaulted Supply.

AVIV compares Bitcoin with the True Market Mean and is shown with the True Market Mean centered at 0. Historical valuation bands use expanding mean and sample standard deviation from 2012. AVIV-NUPL applies the same valuation structure to unrealized profitability.

Updated Bitcoin Supply Redistribution by Address Balance. Daily cohort flows are now calculated from exact address balance transitions instead of estimating cross-band migration from changes in cohort balances and address counts. Positive balance changes are assigned to the ending balance cohort, while negative changes are assigned to the starting balance cohort.

Analysis windows now give more weight to recent daily flows, while relative cohort changes use the average cohort balance across the selected window.

Fixed an issue with bar chart canvas boundaries that could cause bar metrics to render outside the visible chart area. Bar charts now use the correct canvas bounds when calculating the visible range.

New metrics:

• Bitcoin AVIV Ratio
• Bitcoin AVIV-NUPL
• Bitcoin True Market Mean
• Bitcoin Active Market Cap
• Bitcoin Vaulted Market Cap
• Bitcoin Investor Cap
• Bitcoin Active Supply
• Bitcoin Vaulted Supply

Chart navigation and price chart improvements

Added a new chart navigation mode. Direct navigation is now available in Account settings, allowing standard mouse wheel controls for zooming and moving through the chart. The default navigation mode remains available.

Updated the Bitcoin Price chart with historical crossover markers for widely followed crossover pairs: 1D SMA 50/200 Golden Cross and Death Cross, 1W EMA 21/50 crossover, and 1W SMA 50/100 crossover. Historical intersections are marked directly on the chart when a crossover is active.

Improved chart controls, fixed issues with navigation controllers and current value labels, and improved screenshot exports.

Bitcoin Supply Redistribution added

Added Bitcoin Supply Redistribution, a heatmap showing how BTC supply shifts between six address-balance cohorts, from <1 BTC to ≥10k BTC, across timeframes from 3 days to 180 days.

The metric adjusts for addresses moving between cohorts as their balances change and matches accumulation with distribution within each timeframe, providing a supply-neutral view of redistribution across cohorts.

Spent Output Age Bands added

Added Spent Output Age Bands (SOAB), showing the age structure of spent outputs as stacked share bands, with BTC price for market context. SOAB reads spent-side activity by output count, making it the count-weighted companion to Spent Volume Age Bands (SVAB).

Band isolation keeps a selected age band in its true stacked position instead of collapsing it to the bottom, so you can inspect one cohort without losing its place in the full distribution.

New paired and comparison metrics

Added a new group of Bitcoin charts that place related series in the same view: holder cost basis, supply-side balance, miner economics, and capital structure.

New charts:

• Bitcoin STH Realized Price vs LTH Realized Price
• Bitcoin Realized Cap vs Market Cap
• Bitcoin Supply in Profit and Loss (BTC)
• Bitcoin Transaction Fees vs Miner Revenue
• Bitcoin Thermo Cap vs Market Cap

Also includes minor fixes around paired chart rendering, legend behavior, and chart interaction.

Early price history, axis sync, and mobile fixes

Updated the methodology for Bitcoin’s earliest price history. Early BTC markets were thin and fragmented, so small differences there shift long-horizon valuation readings.

This affects charts anchored to historical BTC price or market-value calculations: BTC Price, Market Cap, Realized Price, STH Realized Price, LTH Realized Price, MVRV, MVRV Z-Score, NUPL, and Supply in Profit / Loss.

Added axis sync on Realized Price, STH Realized Price, and LTH Realized Price. The left and right axes now share a scale, so price overlays line up directly without manually rescaling either side.

Fixes log-scale panning on mobile and makes touch panning smoother. Includes minor bug fixes.

Supply in Profit / Loss

Added Supply in Profit / Loss, a composite Bitcoin metric showing the share of circulating supply currently valued above or below its realized cost basis. BTC price is included for market context.

This update also includes bug fixes and interface refinements across the chart workspace.

CoreCharts Version 2

CoreCharts Version 2 introduces a redesigned chart interface with more space for data, cleaner metric reading, and faster interaction across the platform.

Current metric values are now shown directly on the chart, visible at a glance without leaving the visual context. Charts with bands and layered areas have been reworked for more stable rendering and cleaner hover behavior.

Mobile chart interaction has been fully rebuilt. Inspect mode, touch gestures, zoom, and chart navigation are now consistent across screen sizes, with scrolling and inspection separated more cleanly.

Performance has been improved across heavier charts and older devices. Several reported issues have also been fixed in this release. If you notice something that does not work as expected, contact us at bugs@corecharts.com.
