Cycle Duration Dashboard

What is it?

The Cycle Duration Dashboard is the command center for Bitcoin cycle timing. It consolidates four measurements for each historical cycle into a single comparative view: bull phase duration (bottom to top), bear phase duration (top to bottom), full cycle length (bottom to bottom) and accumulation period (bottom to the first close back above the previous cycle top). It answers a question no single metric answers: not how long a cycle lasted, but how its time was divided between expansion and contraction. Read across the completed cycles, one regularity holds and two do not. The bull phase has been stable since cycle 2, at 1,068 then 1,061 then 1,050 days, against 742 for the first. The bear phase has not settled into a trend: 411 days, then 363, then 376. The accumulation period has not lengthened either: 468 days, then 771, then 732.

How to read

Four curves share one axis in days. Each one counts from the cycle bottom and falls back to zero at the next bottom, so the chart reads as a repeating sawtooth, one tooth per cycle, and the teeth can be compared directly. The bull curve climbs from the bottom and freezes the day the cycle tops. The bear curve stays flat at zero until that top, then climbs until the next bottom. The full-cycle curve is the sum of the two, so it keeps climbing for the whole cycle. The accumulation curve climbs from the bottom and freezes on the day price first closes back above the previous cycle top. Where a curve is flat, the phase it measures is over; where it climbs, that phase is still running. The current cycle is therefore read on the curves that are still rising.

Key zones

Cycle breakdown by phase (approximate days): • Cycle 1: Bull ~1,107 | Bear ~410 | Full ~1,152 | Accumulation ~623. • Cycle 2: Bull ~1,068 | Bear ~364 | Full ~1,432 | Accumulation ~779. • Cycle 3: Bull ~1,061 | Bear ~376 | Full ~1,437 | Accumulation ~737. • Bull phase trend: Remarkably stable at ~1,065 days (±45), suggesting a structural constant. • Bear phase trend: Declining from ~410 to ~364 days - bears are getting shorter. • Full cycle trend: Stabilized at ~1,435 days (post-Cycle 1). • Accumulation trend: Growing from ~623 to ~779 days - more time spent below ATH. • Bull/bear ratio: Shifting from approximately 73/27 (Cycle 1) to 74/26 (Cycle 2) to 74/26 (Cycle 3) - the split has stabilized. • Current Cycle 4 tracking: Bull phase elapsed days vs. the ~1,065-day average provides the key timing context.

What to observe

• Phase imbalance: watch for the current cycle's bull/bear split diverging from the two most recent completed cycles, at 75/25 and 74/26. The first cycle sat at 64/36, so the three-quarter share is a recent regularity rather than a law. A significantly higher bull ratio could indicate an elongated cycle; lower could indicate premature exhaustion. • Accumulation period length: A longer accumulation phase (more days below ATH) has historically preceded stronger post-ATH rallies. It represents more time for supply to transfer to strong hands. • Bear phase floor: bear phases have run 411, then 363, then 376 days, so they have not settled into a direction. A fourth reading clearly under 363 would be the first evidence of an actual shortening trend; one above 411 would close the question the other way. • Cycle symmetry: Symmetric cycles (where bull ≈ bear in duration, not magnitude) have historically preceded 'blow-off' tops. Asymmetric cycles with long bulls and short bears have preceded more orderly distribution. • Cross-reference with macro: The dashboard is most valuable when cross-referenced with the macro cycle (dollar, liquidity, interest rates) - cycles that align with favorable macro conditions tend to fill out their full bull-phase duration.

Historical context

The Cycle Duration Dashboard synthesizes what individual metrics show in isolation. Across three complete cycles, the one stable quantity is the bull phase, at 1,068 then 1,061 then 1,050 days once the first cycle (742 days) is set aside as a thin-market outlier. The bear phase has not compressed: 411 days, then 363, then 376. This pattern suggests that market maturation primarily affects the downside - deeper liquidity, stronger hodler conviction, and institutional demand create a floor that gets reached faster. Meanwhile, the fundamental supply-driven bull cycle continues at its natural pace, anchored to the halving. The accumulation period has not grown either: 468 days, then 771, then 732, and 470 for the cycle that broke its previous top in March 2024. The one long stretch is cycle 2, whose bottom sat far below the prior top; reading a trend into four readings that go up once and down twice would be reading noise. This dashboard was essential during the 2022-2023 bear market for providing context: the bear was running shorter than average, and the accumulation phase was on track for a cycle-consistent breakout.

Expert notes

The dashboard is constructed using a standardized cycle definition: Bottom = lowest daily close after the cycle peak, Top = highest daily close before the subsequent bear decline exceeds 50% from peak. This avoids the ambiguity of intra-cycle corrections. The accumulation period is defined as the number of days from the cycle bottom to the first daily close above the previous cycle's top - equivalent to the ATH Break Days metric. Phase percentages are calculated as (phase days / full cycle days × 100). The remarkable stability of the bull/bear ratio at approximately 74/26 across Cycles 2 and 3 suggests a natural equilibrium. In classical Dow Theory terms, this corresponds to a primary bull trend lasting roughly 3x the primary bear trend, which aligns with observations in many commodity cycles. The dashboard feeds 4 independent indications into the TCCI: bull-phase elapsed %, bear-phase elapsed %, accumulation duration anomaly, and phase-ratio deviation.

Common mistakes to avoid

• Treating phase durations as fixed: They are central tendencies with significant variance. The bull phase could be 950 or 1,150 days and still be 'within range.' • Ignoring intra-cycle corrections: A 30-40% drawdown within a bull phase (like May 2021) does not mean the bear has started. The dashboard defines phases by cycle extremes, not intra-cycle moves. • Assuming the current cycle must match previous ratios: Each cycle exists in a unique macro context. The 74/26 ratio is a central tendency, not a law. • Comparing Cycle 1 directly to later cycles: The pre-2013 market was structurally different (minimal liquidity, no real exchanges). Phase comparisons are most reliable from Cycle 2 onward. • Using the dashboard for price targets: It measures time, not price. A full-duration bull phase tells you nothing about how high the price will go.
