Pi Cycle Top Indicator
The Pi Cycle Top Indicator plots two moving averages of Bitcoin's price — the 111-day moving average and the 350-day moving average multiplied by two — and watches for the point where the 111-day average crosses above the doubled 350-day average. The name refers to the mathematical relationship between the two windows, since 350 divided by 111 approximates π.
The indicator is used as a cycle-timing signal: in Bitcoin's prior market cycles, every occurrence of the 111-day average crossing above the doubled 350-day average has occurred within days of a major cycle top, based on the cycles observed to date. When the two lines are converging but have not yet crossed, that condition is sometimes described as a caution or late-cycle zone; when the 111-day average sits well below the doubled 350-day average, that condition has historically corresponded to earlier-cycle or accumulation phases.
Like any indicator built from historical crossovers, the Pi Cycle Top signal describes a pattern observed in a small number of past cycles. A limited number of historical occurrences is not a guarantee that the same relationship will hold in future cycles, and the indicator does not fabricate a probability or timeline for any future crossover.
