The Pi Cycle Top Indicator — A CTDMM Structural Reading

Reading the classical Bitcoin top signal through the 7-phase cycle engine.

Every Bitcoin cycle produces one signal that gets canonised. The Pi Cycle Top — the crossover of the 111-day simple moving average and 2× the 350-day simple moving average — has, historically, marked major cycle tops within a few days of the actual peak. It is elegant, it is famous, and it is fragile. CTDMM treats it as one gear inside a larger cycle engine, not as a standalone oracle.

01

What the Pi Cycle Top Actually Measures

The indicator plots two moving averages of Bitcoin's daily close: the 111-day SMA and 2× the 350-day SMA. When the short average crosses above the long, doubled average, it signals that price has stretched so far above its long-horizon mean that continuation becomes structurally unlikely.

  • 111-day SMA — a medium-horizon trend line responsive to the current cycle's expansion
  • 350-day SMA × 2 — a long-horizon gravity line stretched to catch late-cycle blow-offs
  • Their ratio approximates π (350 ÷ 111 ≈ 3.153), which is where the name comes from — a numeric coincidence, not a market law
  • Historical crossovers: April 2013, December 2013, December 2017, April 2021 — each within days of a major top
The honest framing
The Pi Cycle Top is a mean-reversion trigger with a memorable name. It fires when price accelerates faster than its own long-horizon average can absorb.

Where It Sits Inside the CTDMM 7-Phase Cycle

CTDMM models every market cycle as a 7-phase progression — accumulation, ignition, expansion, euphoria, distribution, capitulation, and reset. The Pi Cycle Top is not a phase; it is an observation that fires almost exclusively inside phase 4 (euphoria) as it hands over to phase 5 (distribution).

Pi Cycle behaviour across the 7 phases
PhaseStatePi Cycle behaviour
01Accumulation111 SMA sits far below 2× 350 SMA — no meaningful signal
02Ignition111 SMA begins rising; gap narrows slowly
03Expansion111 SMA closes on 2× 350 SMA — watch begins
04EuphoriaCrossover fires — Pi Cycle Top triggered
05Distribution111 SMA rolls under 2× 350 SMA within days
06CapitulationBoth lines fall; indicator is silent
07ResetLines re-anchor; the next cycle's clock begins

Why Structure Beats Single Signals

A single-signal reading of Pi Cycle asks: has the line crossed yet? A structural reading asks: which phase are we in, what confirmed the transition, and how does the crossover reinforce or contradict the phase already in progress? CTDMM prefers the second question every time.

  • Signals fire late — the crossover confirms what price already did over the prior weeks
  • Signals overfit — four historical hits is a small sample; the next top may not respect the same geometry
  • Signals ignore context — the same crossover in a bear market's ignition phase would mean something entirely different
  • Structure survives — the 7-phase cycle continues to describe the market even when any individual signal fails
CTDMM reading
Treat the Pi Cycle Top as a confirmation gear, not a prediction. When it fires while the cycle is already in euphoria and other CTDMM observations agree, its confidence rises. When it fires in isolation, it is noise wearing the mask of a signal.

Using the Indicator Inside a CTDMM Workflow

Inside the CTDMM ecosystem the Pi Cycle Top becomes one observation channel, not a strategy. Cortana handles the numeric read; Commander stages the response; Mika contextualises it against the wider structural picture.

  • Cortana — computes the 111-day and 2× 350-day SMAs each session and flags proximity, not just crossover
  • Commander — maps the observation to the current 7-phase state and routes it to the correct protocol
  • Mika — cross-checks with distance, time, and market observations before elevating the reading to the operator
  • Mini Autopilot — never trades a Pi Cycle crossover alone; it requires structural confirmation from at least two other gears
"One indicator is a story. Seven phases are a system. Trade the system."
05

Practical Cautions

Do not treat this as financial advice
The Pi Cycle Top has a small historical sample size and no theoretical guarantee of future accuracy. CTDMM publishes structural readings for research and observation, not as trading instructions.
  • The 350-day SMA lags heavily — early-cycle readings are structurally uninformative
  • Post-2024 halving cycles may compress or extend historical spacings
  • ETF-era spot flows can distort classical late-cycle geometry
  • Any signal that has been publicised for years is priced into positioning — treat crowded signals with suspicion
