Pi Cycle Top Indicator: How Two Moving Averages Called Every Bitcoin Peak
There are plenty of Bitcoin indicators that claim to predict cycle tops, but very few have the track record of the Pi Cycle Top Indicator. It has called every major Bitcoin peak within days -- sometimes within a single day. As someone who has been investing in Bitcoin since 2017, I have watched this indicator in real time, and its precision is both impressive and humbling. Here is everything you need to know about how it works and how to use it wisely.
The Math Behind It
The Pi Cycle Top Indicator is built on two simple moving averages:
- The 111-day moving average (111DMA): The average closing price of Bitcoin over the past 111 days.
- The 350-day moving average multiplied by 2 (350DMA x 2): The average closing price over the past 350 days, then doubled.
The signal occurs when the 111DMA crosses above the 350DMA x 2. That crossover has historically coincided with the exact top of each Bitcoin cycle.
Why these specific numbers? This is where it gets interesting. The ratio 350 / 111 equals approximately 3.153 -- remarkably close to the mathematical constant pi (3.14159). This is where the indicator gets its name. Whether this relationship to pi is coincidental or hints at some deeper mathematical structure in market cycles is debated, but the empirical results speak for themselves.
Historical Accuracy: Three for Three
The Pi Cycle Top Indicator has been tested against three complete Bitcoin market cycles, and its accuracy is striking.
2013 Peak (November 29, 2013) Bitcoin reached its cycle high of approximately $1,100. The 111DMA crossed above the 350DMA x 2 within one day of this peak. The market subsequently crashed over 80% during 2014.
2017 Peak (December 17, 2017) Bitcoin hit $19,783 -- the all-time high that would stand for over three years. The Pi Cycle crossover occurred on the same day. I remember this moment vividly because I was deep in the market. The crossover happened, the price reversed, and what followed was a brutal 84% drawdown over the next twelve months.
2021 Peak (April 14, 2021) Bitcoin reached approximately $64,800 during the first leg of the 2021 bull run. The Pi Cycle crossover triggered within days of this peak. While Bitcoin did make a slightly higher nominal high in November 2021 at $69,000, the April crossover captured the momentum peak -- the point at which the internal structure of the trend broke.
Three complete cycles. Three accurate calls. Each within days of the absolute top. That track record is extraordinarily rare among technical indicators.
How the Crossover Mechanism Works
During normal market conditions, the 350DMA x 2 sits well above the 111DMA. This makes intuitive sense: the longer-term average, when doubled, represents a level of overextension that the shorter-term average rarely reaches.
As a bull market accelerates, the 111DMA rises rapidly -- it responds faster to recent price action. The 350DMA x 2 rises more slowly because it is anchored to a longer history. When the market enters its final parabolic phase, the 111DMA surges upward toward the 350DMA x 2 line.
The crossover itself is the climax. It indicates that short-term price momentum has become so extreme that it has caught up to a level that historically marks unsustainable overextension. Once the cross happens, the short-term momentum exhausts itself, and price reverses.
Think of it as a rubber band being stretched. The 350DMA x 2 is the outer limit of the band. The 111DMA is how far current price action has stretched it. When they meet, the snap-back begins.
What to Watch When It Is Not Crossing
For most of the cycle, the Pi Cycle Top Indicator is dormant -- no crossover, no signal. But that does not mean it is useless during these periods. The distance between the two moving averages provides valuable context:
- Wide gap (111DMA far below 350DMA x 2): The market is nowhere near a top. This is typical of accumulation and early markup phases. You have time.
- Narrowing gap: The market is heating up. Momentum is building. The shorter average is gaining on the longer one. Alert levels should rise.
- Converging rapidly: The parabolic phase may be underway. This is where caution becomes critical. Check this indicator daily.

Limitations: What It Cannot Do
Despite its impressive track record, the Pi Cycle Top Indicator has significant limitations that every investor must understand.
It only signals tops. The Pi Cycle Top tells you nothing about bottoms. It provides no guidance on when to buy -- only a warning about when the party might be ending. For bottom signals, you need other tools like the MVRV Z-Score or the Puell Multiple.
Three data points is a small sample. Three correct calls is impressive, but statistically it is a very small sample size. We cannot calculate meaningful confidence intervals from just three observations. The indicator could fail on its next signal, and we would have no statistical basis for surprise.
False signals are possible. As the Bitcoin market structure evolves with institutional participation, ETFs, and global regulatory frameworks, the dynamics that created those three perfect signals may shift. Moving averages that worked when Bitcoin was driven primarily by retail traders may behave differently in an institutionally dominated market.
It does not tell you how far the correction will go. Even if the crossover perfectly marks the top, it provides no information about the depth or duration of the subsequent decline. The corrections after each signal ranged from 80% to 84% -- but the next one could be 50% or 90%.
Timing is still difficult. Even knowing the crossover is approaching, the final parabolic move can add 30-50% to the price. Selling too early based on anticipation of the cross means leaving significant gains on the table. Waiting for confirmation means selling into the reversal.
How I Use the Pi Cycle Top Indicator
I treat the Pi Cycle Top as a flashing warning light, not an automatic sell trigger. When the two moving averages begin converging, I start scaling out of positions gradually. I do not wait for the exact crossover to sell everything -- that would require perfect timing that no one reliably achieves.
My approach is layered: begin reducing exposure when the gap narrows to within 15-20%, increase the pace of selling as they converge further, and if a crossover occurs, treat it as final confirmation that the cycle top is either here or has just passed.
Combined with MVRV Z-Score readings and Puell Multiple data, the Pi Cycle Top becomes part of a multi-indicator framework that is far more robust than any single signal.
