Pi Cycle Top Indicator
Cross of the 111-day SMA above the 350-day SMA × 2.
When BTC's 111-day moving average crosses above twice the 350-day MA, the market is historically near a cycle top. The signal has fired correctly within days of the 2013, 2017 and 2021 tops — but it's a single indicator from a tiny sample size, not a guarantee.
