14159…) is used in trading

mainly in cyclical analysis, Gann-based strategies, and
Fibonacci relationships. Here are some key ways it is applied:

1. Gann’s Square of 9 and Pi

• W.D. Gann used π in price and time cycles.
• The Square of 9 formula often incorporates π in angle
calculations:
• Angles like 90°, 180°, and 360° are converted using π for
time and price predictions.

2. Pi Cycle Indicator (Crypto & Cycles in Stocks)

• Used in Bitcoin market tops and cycle analysis.
• A common formula is:
• It helps identify major turning points based on periodicity.

3. Fibonacci & Pi Ratios in Trading

• Pi is linked to Fibonacci numbers and is used to find
retracement and extension levels.
• Traders sometimes use multiples of π (e.g., 3.14, 6.28) to
calculate custom support/resistance.

4. RSI & Pi (14-day Cycle)

• The 14-day RSI period is approximately 2π (~6.28 × 2 =
12.56, rounded to 14).
• This shows that natural cycles in markets often align with π-
related time frames.

5. Pi in Market Harmonics & Time Cycles

• π is used in time cycle forecasting, where market reversals
align with multiples of 3.14 days, weeks, or months.
• Some harmonic traders use π in wave formations like
Gartley, Butterfly, and Bat patterns.

Using Pi (π) and Gann in Bank Nifty Trading

W.D. Gann’s trading techniques involve price and time cycles

based on mathematical constants like Pi (3.14159) and 360°
rotations. By combining Pi-based calculations with Gann’s
Square of 9, we can predict key support/resistance levels, trend
reversals, and time cycles in Bank Nifty.

1. Gann Square of 9 and Pi for Bank Nifty Levels

The Square of 9 is a spiral-based system where price and time are

linked through 360° rotations. Pi is used in angle calculations to
predict major turning points.
Formula for Gann Pi Levels:

Where:
• π (Pi) = 3.14159
• N = 45, 90, 180, 270, 360 degrees (key Gann angles)
• Price projections are derived by squaring and adding Pi-
based increments

Example: Predicting Bank Nifty Levels Using Pi &

Gann

Let’s assume Bank Nifty is at 45,000 and we want to find

potential resistance levels based on Gann & Pi.

Step 1: Calculate Gann’s Pi-based Levels

Using the formula:

Now, apply Pi-based increments for different Gann angles:
1. 45° Level:
2. 90° Level:
3. 180° Level:
Step 2: Using These Levels for Trading
• If Bank Nifty is at 45,000, we now know that the next
possible resistances are 45,801, 46,834, and 48,686.
• If price rejects a level and reverses, we can look for shorting
opportunities.
• If price breaks and sustains, we can go long with targets at
the next level.

2. Pi-Based Time Cycles for Bank Nifty

Gann’s theory suggests that time cycles repeat in multiples of Pi

(3.14). Traders use Pi to calculate time-based reversals:

Pi-Based Time Cycle Formula

For example, if a major Bank Nifty top occurred 21 days ago, the
next reversal cycle could be:
So, we expect a potential reversal in 66 days.

3. Combining Pi with MACD & Volume for

Confirmation
• If Bank Nifty is near a Pi-based Gann level (e.g., 46,834)
• MACD shows bearish divergence
• Volume analysis (VPVR) shows strong resistance
• Pi-based time cycle (66 days) aligns with the level

👉 This increases the probability of a reversal.

Final Strategy Summary

✔ Use Gann Pi Levels (Square of 9 + Pi) for Bank Nifty

support/resistance
✔ Watch for price action confirmation at these levels
✔ Use Pi-based time cycles to anticipate trend reversals
✔ Combine with MACD, VPVR, and options data for higher
accuracy

How to Use the Pi Cycle Top & Bottom Indicator in
TradingView

The Pi Cycle Top & Bottom Indicator is designed to identify

market tops and bottoms based on moving average crossovers. It
is widely used in crypto and stock indices for long-term trend
reversal signals.

1. How the Indicator Works

The Pi Cycle Indicator uses two key moving averages:

• Long-Term Moving Average (LMA) → 350-day Simple
Moving Average (SMA)
• Short-Term Moving Average (SMA × Pi) → 111-day SMA
multiplied by 3.1416

When do signals occur?

• Top Signal (Market Peak) → When the 111-day SMA ×
3.1416 crosses above the 350-day SMA.
• Bottom Signal (Market Bottom) → When the 111-day SMA
× 3.1416 crosses below the 350-day SMA.

2. How to Apply It in TradingView

1. Open TradingView and go to your preferred asset (e.g., Bank
Nifty, Bitcoin, or Nifty 50).
2. Click on Indicators (shortcut: / key).
3. Search for “Pi Cycle Top & Bottom” (look for community
scripts or create a custom script).
4. Apply the indicator and adjust settings if necessary (default
values work well).

3. Trading Strategy Using Pi Cycle

A. Spotting Market Tops

• If the 111-day SMA × 3.1416 crosses above the 350-day
SMA, it signals a possible top.
• This means the market is overextended, and a reversal or
correction is likely.
 • Action: Consider exiting long positions or preparing for a short
trade.

B. Spotting Market Bottoms

• If the 111-day SMA × 3.1416 crosses below the 350-day
SMA, it signals a bottom.
• This suggests a buying opportunity as the market is
oversold.
• Action: Look for long entry points or confirmations from other
indicators.

4. Best Timeframes to Use

• Best for Positional Trading → Daily (D) or Weekly (W)
charts.
• Not ideal for intraday trading because it’s designed for
long-term market cycles.

5. How to Improve Accuracy

• Combine Pi Cycle with MACD → Check if MACD is showing a
divergence before taking action.
• Use Volume Analysis → Higher volume near the signal
strengthens its reliability.
• Apply Gann Levels → If a Pi Cycle top/bottom aligns with a
Gann Square of 9 level, it’s more reliable.

The Application of the Mathematical Constant Pi in Financial Trading Strategies

1. Introduction
The mathematical constant pi, denoted by the Greek letter π, is a fundamental concept representing
the ratio of a circle's circumference to its diameter. Its approximate value is 3.14159, and it appears
across numerous scientific and mathematical disciplines. This report aims to address the application
of this constant within the realm of financial trading strategies, as requested by the user. By
examining existing research and technical analysis principles, this analysis will explore the reported
uses of pi in trading, encompassing its role in specific indicators, its relationship with other
mathematical concepts like Fibonacci ratios, its potential in forecasting price movements and
reversal points, and its utilization in time-based analytical techniques. Furthermore, this report will
distinguish the mathematical constant pi from other entities that share the term "Pi," such as the Pi
Network cryptocurrency and the Profitability Index used in corporate finance.
2. The Pi Cycle Top Indicator
A notable application of the mathematical constant pi in financial trading, particularly within the
cryptocurrency market, is the Pi Cycle Top Indicator . This technical analysis tool is designed to
identify potential peaks in the price cycles of Bitcoin and other cryptocurrencies. The indicator's
construction involves two Simple Moving Averages (SMAs): the 111-day SMA and the 350-day SMA
multiplied by a factor of two . A signal for a potential market top is generated when the shorter-term
111-day SMA crosses above the longer-term 350-day SMA multiplied by two . The name of this
indicator arises from the observation that the ratio of the longer period (350 days) to the shorter
period (111 days) is approximately 3.153, a value remarkably close to the mathematical constant pi
(approximately 3.142) . This numerical proximity suggests a deliberate connection between the
chosen moving average lengths and the fundamental constant.
Historically, the Pi Cycle Top Indicator has demonstrated a notable ability to predict Bitcoin market
tops in several previous cycles. For instance, research indicates successful signals preceding the
market peaks of 2013, 2017, and 2021 . These signals reportedly occurred within a few days of the
actual price peaks . The repeated correlation between the indicator's signals and historical market
tops has contributed to its widespread adoption and interest among traders in the cryptocurrency
space. Traders often look to tools with a track record of identifying significant market turning points,
and the Pi Cycle Top Indicator's past performance provides empirical evidence, though limited to a
few market cycles, for its potential utility.
However, it is crucial to acknowledge the inherent limitations of all technical indicators, including the
Pi Cycle Top Indicator . The possibility of false signals, particularly during periods of high market
volatility, is a significant consideration . Therefore, financial analysts recommend using this indicator
in conjunction with other forms of analysis, such as examining volume, momentum indicators, and
even fundamental factors, to increase the robustness of trading decisions. Employing appropriate
risk management strategies, such as setting stop-loss orders, is also essential when utilizing any
technical indicator. Relying solely on the Pi Cycle Top Indicator carries inherent risks, underscoring
the importance of seeking confirmation from a diverse set of analytical tools and considering the
broader market context.
Interestingly, the concept of using moving average ratios related to pi extends beyond identifying
market tops. A variation known as the Pi Cycle Bottom indicator exists, which employs different
moving averages (the 150-day exponential moving average and a multiple of the 471-day simple
moving average) to identify potential market bottoms . The development of an indicator for both
market tops and bottoms based on a similar principle suggests a broader belief in the cyclical nature
of markets potentially governed by mathematical relationships connected to pi. This implies an
attempt to create a comprehensive cyclical analysis toolkit centered around this mathematical
constant.
To illustrate the historical performance of the Pi Cycle Top Indicator, the following table summarizes
key instances:
| Cycle | Signal Date | Approximate Price at Signal (BTC) | Actual Peak Date | Approximate Price at
Peak (BTC) | Time Difference (Days) |
|---|---|---|---|---|---|
| 2013 | April 5, 2013 | $142.30 | April 9, 2013 | $230 | 4 |
| 2017 | December 14, 2017 | $16,341 | December 17, 2017 | $19,927 | 3 |
| 2021 | April 3, 2021 | $58,931 | April 14, 2021 | $64,816 | 11 |
This data highlights instances where the indicator provided signals relatively close to the actual
market peaks, contributing to its reputation among cryptocurrency traders.
3. Pi and Fibonacci Ratios in Trading
The Fibonacci sequence is a series of numbers starting with zero, where each subsequent number is
the sum of the two preceding ones (0, 1, 1, 2, 3, 5, 8, ...) . A significant mathematical relationship
within this sequence is the Golden Ratio, often denoted by the Greek letter Phi (Φ), which is
approximately 1.618 . This ratio is observed when any number in the Fibonacci sequence is divided
by its preceding number, and it appears in various natural phenomena. In technical analysis,
Fibonacci ratios derived from this sequence, such as 61.8% (obtained by dividing a number by the
subsequent number), 38.2% (obtained by dividing a number by the number two places higher), and
23.6% (obtained by dividing a number by the number three places higher), are widely used to
identify potential retracement and extension levels in price movements . Traders employ these ratios
to forecast potential support and resistance levels during price corrections or continuations of trends
. Many trading platforms, including tools like Zerodha's Pi, offer built-in Fibonacci retracement tools
to aid traders in applying these concepts to their charts .
Intriguingly, mathematical research has revealed connections between the constant pi and the
Golden Ratio, Phi . These relationships include various approximations and trigonometric functions
that link the two constants . For example, one approximation suggests that 6/5 multiplied by Phi
squared is approximately equal to pi (6/5 * Φ² ≈ π) . While these mathematical links are fascinating,
the available research does not indicate a widespread direct application of these specific formulas in
generating trading signals or deriving standard Fibonacci-based trading tools. The connection
between pi and Phi in the context of trading appears to be more of a theoretical curiosity rather than
a practical, widely adopted technique based on the provided information.
Standard Fibonacci tools used in trading platforms primarily rely on the ratios directly derived from
the Fibonacci sequence itself, not directly from mathematical formulas explicitly linking pi and Phi .
Traders utilizing Fibonacci retracements, extensions, and other related tools typically input the high
and low points of a price swing, and the software automatically calculates the levels based on the
standard Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%, and extensions beyond 100%). There is
no clear indication in the research that these calculations inherently involve or are derived from the
mathematical constant pi.
It is worth noting the existence of a trading strategy referred to as the "RSI Pi Trading Strategy" .
However, in this context, the term "Pi" does not refer to a direct mathematical derivation using the
constant. Instead, it appears to be a mnemonic or an approximation, with the strategy utilizing
Relative Strength Index (RSI) periods of 3 and 14 (as 3.14 is an approximation of pi) . The strategy
involves specific conditions based on these RSI periods on multiple timeframes to identify potential
buying opportunities . This example illustrates a more symbolic or approximate use of the term "Pi"
in a trading strategy, rather than a deep mathematical integration of the constant itself.
4. Pi in Time-Based Analysis and Cycle Theory
Cycle analysis in financial markets is a discipline that seeks to identify recurring patterns and
predictable timeframes in market movements to anticipate future price behavior. This approach
assumes that markets operate in cycles, influenced by factors such as investor psychology and
economic trends.
W.D. Gann was a prominent figure in technical analysis who developed trading techniques based on
angles and geometric constructions to analyze the relationship between price and time . Gann's
methods, including Gann angles, Gann fans, and the Square of Nine, aim to identify support and
resistance levels, as well as potential market tops and bottoms . While Gann's work involves intricate
mathematical and geometric principles, the research snippets provided do not explicitly mention the
direct use of the mathematical constant pi in his core techniques. Gann's analysis often involves
dividing price and time into proportional parts using specific angles (like 45 degrees) and geometric
patterns, but a direct incorporation of the value of pi is not evident in the descriptions of his
methodologies .
Martin Armstrong's "Pi Cycle Theory," also known as the Economic Confidence Model, suggests that
shifts in market sentiment occur approximately every 8.6 years, referencing pi in the broader context
of cyclical analysis . This theory posits that public confidence in markets waxes and wanes in
response to global events, creating long-term cycles. It is important to distinguish this theory from
the Pi Cycle Top Indicator, which is specific to cryptocurrency analysis. The mention of pi in
Armstrong's theory seems to relate to its general association with cyclical phenomena and
probability, rather than a specific mathematical derivation involving the constant within the model as
described in the snippet . Notably, Armstrong's reputation is marked by controversy due to past legal
issues .
Beyond the Pi Cycle Top Indicator, the research does not provide significant examples of other
established time-based analysis techniques that directly incorporate the mathematical constant pi in
their construction. While cycle analysis is a broad field encompassing various methodologies, the Pi
Cycle Top Indicator remains the most prominent specific instance of a time-based trading indicator
that explicitly references pi through the ratio of its moving average periods. Other time-based
techniques may rely on different mathematical or statistical methods, such as Fourier analysis or
Hurst exponents, without direct reference to pi.
5. Other Potential (or Misinterpreted) Uses of "Pi" in Trading
It is essential to distinguish the mathematical constant pi from the cryptocurrency known as "Pi
Network" (PI), which is discussed extensively in several of the provided research snippets . The Pi
Network is a decentralized cryptocurrency project designed to be mined on smartphones . The
technical analysis, price predictions, and market discussions surrounding "Pi Network" (PI) are
entirely unrelated to the application of the mathematical constant pi in trading strategies. Examples
from the snippets include discussions of PI's price history, trading volume, market capitalization,
technical indicators like falling wedge patterns and MACD, potential price targets, and the impact of
exchange listings . The significant amount of information available about the Pi Network
cryptocurrency necessitates this clear differentiation to avoid confusion.
Furthermore, the term "PI" is also used as an abbreviation for the "Profitability Index" in the context
of corporate finance, as highlighted in several research snippets . The Profitability Index (PI) is a
capital budgeting metric used to evaluate the attractiveness of potential projects or investments by
comparing the present value of future cash flows to the initial investment . The formula for PI is
typically calculated as the Present Value of Future Cash Flows divided by the Initial Investment . A PI
greater than 1 generally indicates that the project is expected to generate value and should be
pursued . This application of "PI" is entirely separate from the mathematical constant pi and pertains
to a different domain within finance.
6. Effectiveness and Limitations of Using Pi in Trading
Evaluating the effectiveness of trading techniques based on the mathematical constant pi primarily
centers on the historical performance of the Pi Cycle Top Indicator within the cryptocurrency market.
The observed correlation between the indicator's signals and past Bitcoin market tops suggests a
potential usefulness for identifying overheated market conditions . However, it is important to
consider that this correlation might be coincidental or reflective of underlying market cycles that
happen to align with the specific moving average periods used in the indicator's construction.
Without a robust theoretical framework explaining why these specific periods, with a ratio
approximating pi, should consistently predict market tops, the observed effectiveness remains largely
empirical. The research provides limited evidence of other direct applications of the mathematical
constant pi leading to consistently profitable trading strategies in broader financial markets.
The Pi Cycle Top Indicator, despite its historical accuracy in certain instances, has inherent
limitations . As previously mentioned, it is prone to generating false signals, particularly during
periods of significant market volatility . Over-reliance on this single indicator without confirmation
from other technical analysis tools or consideration of fundamental factors can lead to suboptimal
trading decisions. More broadly, the complexity and inherent randomness of financial markets pose
limitations to the predictive power of any single mathematical constant. Market movements are
influenced by a multitude of factors, including economic news, geopolitical events, investor
sentiment, and large institutional trading activities, many of which are not directly tied to
fundamental mathematical constants like pi. Furthermore, there is a risk of overfitting when
identifying patterns related to specific mathematical constants in historical data. A pattern that
appears significant in the past might not hold true in future market conditions.
The rationale behind using a mathematical constant like pi in financial markets appears to stem from
a combination of empirical observation and a belief in underlying mathematical structures governing
market behavior. In the case of the Pi Cycle Top Indicator, the observed correlation between the
moving average ratio and market tops likely provided the initial impetus for its development and
adoption. Some proponents of applying mathematical constants in trading might also subscribe to
the idea that financial markets exhibit fractal properties or operate according to underlying
mathematical harmonies that are reflected in fundamental constants like pi and the Golden Ratio.
Additionally, in some less evidence-based approaches, there might be an element of numerological
or esoteric belief in the significance of certain numbers.
7. Trading Software and Platforms
The research snippets indicate that various charting platforms likely offer the functionality required
to implement the Pi Cycle Top Indicator. This indicator is constructed using standard Simple Moving
Averages, which are widely available on most trading software . Traders can typically customize
moving average periods and apply mathematical operations to them within these platforms. While
Zerodha's Pi platform is mentioned as offering Fibonacci retracement tools , the research does not
specifically highlight any trading platforms that offer dedicated, pre-built tools explicitly based on
other applications of the mathematical constant pi in trading beyond the Pi Cycle Top Indicator.
However, traders with programming or scripting skills could potentially implement custom indicators
or trading strategies involving pi-related calculations on platforms that allow for such customization.
8. Conclusion
In summary, the mathematical constant pi is reportedly used in financial trading primarily through
the Pi Cycle Top Indicator, a technical analysis tool popular in the cryptocurrency market for
identifying potential market tops in Bitcoin. This indicator's name and construction are linked to the
numerical approximation of pi through the ratio of its 350-day and 111-day moving average periods.
While the indicator has shown some historical correlation with market peaks, it is essential to
recognize its limitations, including the potential for false signals. The rationale behind using pi in this
context appears to be rooted in empirical observation of past market cycles.
Beyond the Pi Cycle Top Indicator, the direct application of the mathematical constant pi in other
established trading strategies is not prominently featured in the provided research. While
mathematical relationships exist between pi and other concepts relevant to trading, such as
Fibonacci ratios, their direct utilization in standard trading tools is not evident. Furthermore, it is
crucial to distinguish the mathematical constant pi from the cryptocurrency "Pi Network" and the
"Profitability Index" used in corporate finance, as these are unrelated concepts that share the same
or similar names.
Traders interested in exploring pi-based trading techniques should approach them with a critical and
analytical mindset. While the Pi Cycle Top Indicator offers an intriguing example of a potential
application, rigorous testing and integration with broader trading strategies are essential. The
complexity and inherent uncertainties of financial markets suggest that relying solely on any single
mathematical constant for trading decisions carries significant risks. Therefore, a balanced
perspective that combines various analytical approaches and sound risk management principles is
paramount for navigating the financial markets effectively.
