Bitcoin Pi Cycle Top: what it is and today's value
The Pi Cycle Top Indicator compares the 111-day moving average of price with twice the 350-day moving average. When the 111DMA crosses above 2×350DMA it has flagged, within a few days, Bitcoin's major tops of 2013, 2017 and 2021. We show it as the ratio 111DMA ÷ (2×350DMA): as it approaches 1, the crossover (top) is near.
Formula: 111-day moving average ÷ (2 × 350-day moving average).

How to read it
Below 0.75 the top is far off; between 0.75 and 1 price accelerates and the crossover nears; at 1 the 111DMA crosses 2×350DMA → cycle-top signal.
| Range | Zone |
|---|---|
| < 0.75 | far from top |
| 0.75 – 1 | approaching top |
| ≥ 1 | top signal fired |
