BITCOIN AND ALTCOIN PI CYCLE TOP INDICATOR
What is the Pi Cycle Top Indicator?
The Pi Cycle Top indicator is a technical analysis tool designed to predict Bitcoin market cycle highs by identifying the crossovers between the 111-day moving average and twice the 350-day moving average. It is widely used to anticipate market tops by signaling potential peak points when these two moving averages intersect, showing historical precision of around 3 to 7 days in predicting macro cycle tops.

How the Pi Cycle Top Indicator works
The Pi Cycle Top Indicator is a Bitcoin price model created by Philip Swift that has predicted Bitcoin's major market cycle tops with exceptional historical accuracy. The indicator uses two moving averages of Bitcoin's price: the 111-day MA and the 350-day MA multiplied by two (350MA × 2). The signal fires when the 111-day MA crosses above the 350MA × 2 — a crossover that has occurred within three days of Bitcoin's actual all-time high in the 2013, 2017, and 2021 bull market cycles.
The mathematical curiosity behind it
The mathematical curiosity at the heart of the model is that 350 divided by 111 equals approximately 3.153 — remarkably close to pi (π ≈ 3.14159). While there is no fundamental economic explanation for why this ratio describes Bitcoin's cycle behavior, the empirical track record across three separate market cycles is difficult to dismiss. The doubled 350-day MA creates a long-term ceiling for Bitcoin's price that has proven extremely difficult to sustain above, while the faster 111-day MA measures the rate at which price is approaching that ceiling. When the two converge and cross, it has historically marked the moment of peak euphoria — the point beyond which distribution outweighs accumulation and a major top is imminent.
Using it as a late-cycle warning
Traders use the Pi Cycle Top Indicator as a late-stage bull market warning system rather than an entry timing tool. Indicators like MVRV Z-Score, Hash Ribbons, and Realized Price are better suited for identifying accumulation periods. The Pi Cycle Top is specifically designed to signal when a cycle peak may be approaching and when capital preservation should take priority over continued exposure. Given its near-perfect historical track record and its derivation from simple, widely available price data, it remains one of the most closely watched cycle indicators among Bitcoin researchers and long-term investors who prioritize risk management through market cycles.
Frequently Asked Questions
What is the Pi Cycle Top Indicator?
Created by Philip Swift, it tracks two moving averages of Bitcoin's price and signals when the shorter one crosses above a multiple of the longer one. Those crossings have landed close to Bitcoin's major cycle peaks in past cycles.
Where does the name come from?
The two periods used, 350 and 111 days, produce a ratio of about 3.153, which is close to pi. That coincidence gave the indicator its name. It is a numerical curiosity rather than a reason the model works.
How accurate has it been?
It has signalled close to previous Bitcoin cycle tops, which is why it is widely followed. That record covers very few events, and any model fitted to a handful of past peaks risks describing history rather than predicting the future.
How should the indicator be used?
As a late-stage warning rather than an entry or exit trigger. It only produces a signal near the end of a strong advance, so it says nothing during the rest of the cycle and offers no guidance about bottoms.
Is there an equivalent for market bottoms?
Yes, the Pi Cycle Bottom Indicator applies the same idea to identify cycle lows instead of peaks. The two are separate tools built on the same moving average concept, and neither implies anything about the other.
