Bitcoin’s price cycles are not random—they follow patterns etched in data. The Pi Cycle Top Indicator, developed by Philip Swift in 2019, distills these patterns into a razor-sharp tool for anticipating market peaks. By harnessing two meticulously calibrated moving averages, it reveals when euphoria has pushed prices beyond sustainable limits.

The Science of the Signal

At its core, the indicator juxtaposes two critical metrics: the 111-day moving average (111DMA), reflecting short-term momentum, and the 350-day moving average doubled (350DMA x2), a magnified lens on long-term trends. The ratio between these periods—3.153—mirrors the mathematical constant Pi (3.142), a serendipitous alignment that lends the tool its name. When the 111DMA surges past the 350DMA x2, it flashes a warning: Bitcoin’s ascent may be overheating.
