The Pi Cycle Top Indicator has gained a reputation as one of the most reliable tools for identifying potential market peaks in Bitcoin’s price cycle. With a history of accurately signaling major tops—followed by steep corrections between 52% and 86%—this technical indicator is worth understanding for any serious crypto investor. In this guide, we’ll break down how the Pi Cycle Top works, analyze its historical 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. Let’s examine each instance to understand its predictive power.
2013: The First Signal
On April 5, 2013, the indicator flashed its first top signal. Bitcoin’s price dropped 65.5% within 11 days. However, it briefly surged nearly double in the days immediately following the signal, showing how volatile early-market cycles were due to low liquidity and a tiny market cap.
While this signal was technically correct, many analysts view it as less reliable due to Bitcoin’s nascent stage at the time—valued at just a few billion dollars globally.
December 2013: One Day Before the Peak
The second signal triggered on December 3, 2013, just one day before Bitcoin reached its cycle high. This was followed by a brutal 86.11% decline over the next 623 days. The timing was nearly perfect, reinforcing early confidence in the indicator.
December 2017: Spot-On Again
On December 16, 2017, the third top signal appeared—again, one day before Bitcoin hit its all-time high near $20,000. Over the next year, the price plunged 84.03%, marking one of the most infamous bear markets in crypto history.
April 2021: A Slight Delay but Still Valid
The fourth and most recent signal occurred on April 12, 2021. Bitcoin peaked two days later at nearly $65,000. From the signal date to June 22nd (71 days), the price fell 52.94%—a smaller drop in percentage terms, but still significant given Bitcoin’s trillion-dollar market cap at the time.
Despite these strong results, it's crucial to note that not all major tops have been predicted by the indicator. Two notable exceptions include:
- June 26, 2019: Bitcoin dropped 71.98% over 261 days without a Pi Cycle Top signal.
- November 10, 2021: A 77.57% decline followed over 376 days—again, no prior signal.
This shows that while the indicator is powerful, it isn’t infallible. Relying solely on it could cause missed risk warnings.
How Does the Pi Cycle Top Indicator Work?
Created by crypto analyst Philip Swift of LookIntoBitcoin, the Pi Cycle Top Indicator uses a simple yet insightful moving average crossover strategy.
The Formula
A “top signal” is generated when:
Bitcoin’s 111-day moving average crosses above double the value of its 350-day moving average.
- The 111-day MA (orange line) reflects medium-term momentum.
- The 350-day MA (green line) represents long-term trend strength.
- When the shorter-term average exceeds twice the longer-term average, it suggests an extended, potentially unsustainable rally.
Why Does It Work? Three Theories
1. Extended Rally Detection
When short-term prices surge far beyond long-term averages, it often indicates overheating. Historically, such extremes precede major corrections.
2. The Mathematics of Pi (π)
Interestingly, dividing 350 by 111 gives approximately 3.153—very close to π (3.142). This mathematical curiosity may not be coincidental. Pi appears in natural cycles—from planetary orbits to wave patterns—suggesting that market cycles might follow similar harmonic principles.
3. Market Psychology & Self-Fulfilling Prophecy
Because the indicator is widely followed, traders may act on the signal itself. When many investors sell simultaneously upon its trigger, it can accelerate or even cause the predicted downturn.
Note: Like the Fibonacci retracement tool, which uses nature-based ratios to predict price levels, the Pi Cycle taps into patterns that resonate across financial markets.
What Does the Pi Cycle Top Suggest About Bitcoin’s Next Peak?
As of now, both moving averages are trending upward—the 111-day MA is rising toward double the 350-day MA, but hasn’t crossed it yet. This suggests:
- The bull market cycle has not ended.
- There may still be room for further price appreciation.
However, consider these key scenarios:
Bearish Warning Signs
If Bitcoin’s price drops below the 111-day moving average before the crossover occurs, it could indicate weakening momentum—even without a formal top signal. This pattern was observed after both the June 2019 and November 2021 peaks.
Bullish Acceleration Signal
Conversely, if Bitcoin surges above double the 350-day MA, it may enter the final explosive phase of the bull run. This zone is typically marked by extreme volatility and FOMO-driven buying.
Should You Use the Pi Cycle Top Indicator in Your Strategy?
Yes—but with caution.
The indicator has demonstrated strong historical accuracy, correctly identifying four major tops within days of their occurrence. However:
- It missed two significant corrections since 2019.
- Bitcoin’s market structure has evolved: ETFs, institutional involvement, and algorithmic trading now play larger roles.
- Large players may anticipate retail reactions to well-known indicators like this one and exploit them through strategic positioning (a concept explored in Wyckoff methodology).
Therefore, use the Pi Cycle Top as one tool among many, not a standalone decision-maker.

Frequently Asked Questions (FAQ)
Q: What is the Pi Cycle Top Indicator?
A: It’s a technical analysis tool that signals potential Bitcoin market tops when the 111-day moving average crosses above double the 350-day moving average.
Q: How reliable is the Pi Cycle Top Indicator?
A: It has accurately predicted four major Bitcoin tops since 2013, though it failed to signal two significant peaks in 2019 and 2021.
Q: Can I rely solely on this indicator to sell my Bitcoin?
A: No. While powerful, it should be combined with other metrics like on-chain data, sentiment analysis, and volume trends for better accuracy.
Q: Why are the numbers 111 and 350 used?
A: These values were empirically derived. Their ratio (~3.15) approximates pi (π), suggesting a possible link to natural cyclical patterns.
Q: Has the indicator ever given a false signal?
A: Not exactly false—but it has missed some tops. Also, macroeconomic events or black swan shocks can override any technical signal.
Q: Where can I view the Pi Cycle Top Indicator?
A: It’s available on platforms like TradingView, where you can apply custom scripts to visualize both moving averages and crossover points.
Final Thoughts
The Pi Cycle Top Indicator remains one of the most compelling tools in cryptocurrency technical analysis. Its blend of mathematical elegance and empirical success makes it a favorite among seasoned traders.
But remember: no single indicator guarantees future performance. Markets evolve, participants grow more sophisticated, and new dynamics emerge constantly.
Use the Pi Cycle Top as a strategic compass, not a crystal ball—and always combine it with broader market context for optimal results.
