The Pi Cycle Top Indicator has earned a reputation as one of the most reliable tools for identifying potential market peaks in Bitcoin’s price cycle. With a historical track record of signaling major tops—followed by steep corrections—it offers valuable insights for traders and long-term investors alike. In this comprehensive guide, we’ll break down how the indicator works, examine its accuracy, and explore what it could mean for Bitcoin’s next major price movement.
How Accurate Is the Pi Cycle Top Indicator?
Since 2013, the Pi Cycle Top Indicator has generated four major "top signals"—each closely aligning with a significant peak in Bitcoin’s price. What makes this particularly compelling is that every signal was followed by a substantial market correction ranging from 52% to over 86%.
Let’s take a closer look at each instance:
1. April 5, 2013 – 65.5% Drop
The first signal occurred when Bitcoin was still in its infancy. Just days after the crossover, the price plummeted by more than 65%. However, due to Bitcoin’s extremely low market cap at the time—only a few billion dollars—price swings were far more volatile and easily manipulated. While technically accurate, this early signal may carry less weight in today’s mature market environment.
2. December 3, 2013 – 86.11% Drop Over 623 Days
This signal appeared just one day before Bitcoin reached its cycle high. The subsequent bear market lasted well over a year and a half, with prices eventually falling nearly 87%. This long-term correction underscores how powerful and timely the indicator can be.
3. December 16, 2017 – 84.03% Drop Within a Year
Again, the signal flashed just before the all-time high of nearly $20,000. Over the next 364 days, Bitcoin lost over 84% of its value. Given the massive retail participation during this bull run, the precision of the signal remains striking.
4. April 12, 2021 – 52.94% Drop in 71 Days
The most recent signal preceded the $65,000 peak by just two days. Although the percentage drop wasn't as severe as previous cycles, it occurred in a market valued at over $1 trillion—demonstrating that even in larger, more liquid markets, the indicator retains relevance.

It’s important to note, however, that not all major tops have been predicted by this indicator. For example:
- June 26, 2019: Bitcoin dropped 71.98% without a Pi Cycle Top signal.
- November 10, 2021: Another top followed by a 77.57% decline—again, no signal was triggered.
These exceptions highlight that while the Pi Cycle Top is a powerful tool, it should not be used in isolation.
Understanding How the Pi Cycle Top Indicator Works
Developed by crypto analyst Philip Swift of LookIntoBitcoin, the Pi Cycle Top Indicator relies on two key moving averages:
- 111-day moving average (short-term)
- 350-day moving average (long-term)
A “top signal” is generated when the 111-day MA crosses above double the value of the 350-day MA.
This mathematical threshold creates a strong signal of market overheating. When short-term momentum significantly outpaces long-term trends—specifically doubling it—it often indicates an unsustainable rally phase.
But why does this work? There are several compelling theories:
1. Extended Rally Detection
When Bitcoin’s price surges rapidly enough to push the 111-day average above twice the 350-day level, it suggests extreme bullish momentum. Historically, such extensions tend to correct sharply.
2. The Mathematical Significance of Pi (π)
Interestingly, dividing 350 by 111 gives approximately 3.153, very close to π (3.142)—the mathematical constant representing the ratio of a circle's circumference to its diameter. This number appears throughout nature, physics, and even financial cycles. Some analysts believe this numerical symmetry reflects inherent cyclical patterns in market behavior.
3. Self-Fulfilling Prophecy Through Market Awareness
As more traders monitor this widely recognized indicator, their collective actions can amplify its predictive power. When the signal triggers, widespread selling pressure may accelerate the expected downturn.

What Does the Indicator Suggest About Bitcoin’s Next Top?
Currently, both moving averages are trending upward—indicating an ongoing bull phase. The 111-day MA is approaching double the 350-day MA but hasn’t crossed it yet. Based solely on this metric, Bitcoin’s bull run may still have room to grow.
However, there are key warning signs to watch for:
- If Bitcoin’s price falls below the 111-day moving average, it could signal weakening momentum—even without a formal Pi Cycle Top trigger.
- Conversely, if price surges above double the 350-day MA, it might enter the final, hyper-volatile leg of the bull market.
This late-stage acceleration often brings rapid gains—but also sets the stage for an imminent reversal.
Should You Use the Pi Cycle Top Indicator in Your Strategy?
Absolutely—but with caution.
The indicator has demonstrated remarkable consistency in identifying past tops, making it a valuable component of any technical analysis toolkit. However, relying on it exclusively would be risky.
Bitcoin has evolved significantly since earlier cycles:
- Institutional adoption has increased.
- Bitcoin ETFs now influence market dynamics.
- Large players understand retail sentiment and may exploit predictable patterns like this one.
This means sophisticated actors could potentially manipulate price action around expected signals—a concept explored in depth through methods like the Wyckoff strategy.
Therefore, consider combining the Pi Cycle Top Indicator with other tools:
- On-chain metrics (e.g., exchange outflows, whale accumulation)
- Funding rates and open interest
- Macro indicators and sentiment analysis

Frequently Asked Questions (FAQ)
Q: What exactly triggers a Pi Cycle Top signal?
A: A signal occurs when Bitcoin’s 111-day moving average crosses above double the value of its 350-day moving average—suggesting an overheated market.
Q: Has the Pi Cycle Top ever failed?
A: Yes. Major peaks in June 2019 and November 2021 occurred without a signal, showing that other factors can drive tops independently.
Q: Can I use this indicator for altcoins?
A: Not reliably. The Pi Cycle Top was designed specifically for Bitcoin and reflects its unique halving-driven cycles.
Q: How soon after a signal does a crash happen?
A: Corrections typically begin within days or weeks, though full bear markets can unfold over months.
Q: Is the indicator available on popular platforms?
A: Yes, you can add the Pi Cycle Top Indicator on TradingView using custom scripts or public templates.
Q: Does the indicator work in real time?
A: Yes, it updates daily based on closing prices and is widely followed by analysts tracking Bitcoin’s macro trends.
Final Thoughts
The Pi Cycle Top Indicator isn’t infallible—but its ability to capture macro-level market extremes makes it one of the most respected tools in Bitcoin technical analysis. By understanding its mechanics, limitations, and context within broader market conditions, you can use it to enhance your timing and risk management.
As always, combine signals with multiple forms of analysis and maintain disciplined risk controls. Markets evolve—and so should your strategies.
