What This Chart Shows
The Trend Channel fits a straight line through Bitcoin's price on a logarithmic scale — a constant-growth-rate regression of the daily close over time — and wraps it in standard-deviation bands. The trend line is what Bitcoin has compounded at on average; the ±σ bands describe how far above and below that line price has historically wandered.
- Trend — the log-linear regression line. Its slope is Bitcoin's long-run compound growth rate over the fit window.
- ±1σ bands — one standard deviation of the residuals around the trend. Price spends most of its time inside this channel.
- ±2σ / ±3σ bands — the rarer extremes. Touches of the lower bands have lined up with cycle bottoms; the upper bands with blow-off tops.
- The σ reading — the single number above the chart: how many standard deviations today's price sits from trend. It is the whole signal.
How to Read It
Watch the σ reading, not the dollar price. Below −1σ Bitcoin is historically stretched cheap relative to its own trend; above +1σ it is stretched expensive. Near 0σ it is simply on trend. The further price sits from the line, the more mean-reversion pressure the model implies — in either direction. Because the fit is frozen on a mature-market window, the channel is a slow, weekly-check-in valuation gauge, not an intraday tool.
The shaded extension on the right is the forward channel: the same trend and bands projected into the coming years. It shows where the historical range would sit over time — it is not a forecast of where price will actually trade.
Frequently Asked Questions
What is the Bitcoin Trend Channel?
A log-linear regression of Bitcoin's price over time, drawn with ±1/2/3σ standard-deviation bands. It frames price against a constant-growth trend so you can see whether Bitcoin is cheap or expensive relative to its own history.
What does the σ reading mean?
It is how far price sits from the trend line, measured in standard deviations. Near 0σ is on-trend; below −1σ is a stretched-cheap zone; above +1σ is stretched-expensive.
Is the forward channel a prediction?
No. It only extends the existing trend and its bands into the future to show where that range would sit. It is a projection of the model, not a forecast of price.
