How to read it
Pi Cycle Top fires when the 111-day moving average crosses above the 350-day MA × 2. The name comes from the ratio 350/111 ≈ π.
Historically the signal has fired within a few days of every major BTC cycle top (April 2013, December 2013, December 2017, April 2021). Each red marker on the chart is a signal that fired; the date table below lists them all explicitly.
