How the Pi Cycle Top indicator works
The Pi Cycle Top indicator compares two transformed Bitcoin moving averages. Its historical signals are visually notable, but the rule was selected from past data and should not be treated as a guaranteed top detector.

The crossover rule
The commonly cited construction compares the 111-day moving average with twice the 350-day moving average.
It is a slow trend indicator. A crossover can arrive after a major move and does not define execution price or risk.
Backtest and regime risk
A small number of historical cycles is not enough to establish a stable law. Parameter selection can also overfit past peaks.
Use it as one cycle observation alongside liquidity, valuation, positioning, and a pre-defined exit plan.
Frequently asked questions
