Pi Cycle Bottom/Top

When the fast 111-day SMA crosses above twice the 350-day SMA, the Pi Cycle Top has historically flagged cycle peaks with eerie precision — within days of the 2013, 2017 and 2021 tops. The name comes from 350/111 ≈ π.

It is a curve-fit discovery, not a theory — there is no economic reason the ratio should be π — so treat each new cycle as an out-of-sample test. It fires rarely (a handful of events in 15 years), which is exactly what makes it worth marking on the chart.
