The Short-Term Index (STIX) serves as a valuable tool in market analysis for assessing the intensity and scope of market trends. It provides valuable insights into whether a majority of stocks in a specific market are moving upwards or downwards, allowing traders and analysts to gauge the overall sentiment.
To calculate the STIX, one must determine the ratio of advancing stocks to the total number of advancing and declining stocks within a specific timeframe. This calculation incorporates an exponential moving average (EMA) applied to the ratio, which gives more weight to recent data points. This makes the STIX responsive to short-term fluctuations in market breadth.
By utilizing the STIX, traders and analysts can identify periods of market strength or weakness. A high STIX value indicates a robust market with a larger proportion of advancing stocks, indicating positive market breadth. Conversely, a low STIX value suggests market weakness, characterized by a higher proportion of declining stocks and negative market breadth.
The STIX serves various purposes, including confirming trends and analyzing divergences. For example, when the STIX rises alongside an upward price trend, it confirms a bullish trend. Conversely, if the STIX declines while prices continue to rise, it may indicate a potential divergence, advising caution.
It’s important to note that the parameters for calculating the STIX, such as the time period for the EMA, can be adjusted based on individual preferences and the specific market being analyzed. Traders and analysts often customize the STIX to align with their trading strategies and preferred timeframes.
Overall, the Short-Term Index (STIX) is an indispensable tool for traders and analysts, providing insights into the breadth and strength of market trends. By examining the ratio of advancing stocks to total stocks and incorporating the EMA for a smoother representation, the STIX delivers valuable insights into market dynamics.
Unlike some other well-known indicators, the Short-Term Index (STIX) does not have a single defined creator or originator. Although it was first published in “The Polymetric Report”, it is a concept that has evolved over time, with various analysts and traders adapting and refining its calculation to assess market strength and breadth.
It’s important to understand that technical analysis indicators and concepts are often the result of collaborative efforts, building upon the work of multiple contributors. Although the specific individual credited with creating the STIX remains unidentified, it is highly likely that the indicator’s development involved the contributions of numerous market analysts and technicians in the field of technical analysis.

Computing the Short-Term Index (STIX) Indicator
The STIX serves as a useful technical indicator in market analysis, providing insights into the breadth and strength of a market trend. Its calculation involves utilizing the exponential moving average (EMA) to determine the ratio of advancing stocks to the total number of advancing and declining stocks.
The formula for calculating the STIX can be expressed as follows:
STIX = EMA(Advancing Stocks / (Advancing Stocks + Declining Stocks))
In this formula, the EMA represents an exponential moving average, a weighted average that assigns greater importance to recent data points. The numerator, “Advancing Stocks,” denotes the count of stocks that have experienced value increase over a specified time period. The denominator, “(Advancing Stocks + Declining Stocks),” encompasses the total number of stocks that have either advanced or declined during that same time period.
To calculate the STIX, one would compute the EMA of the aforementioned ratio and utilize the resulting value as the STIX for the specific time frame.
Typically, when the STIX exceeds 50, it indicates a market where advancing stocks dominate relative to the total number of advancing and declining stocks. This suggests positive market breadth. Conversely, a STIX below 50 suggests a scenario where declining stocks outnumber advancing stocks, implying negative market breadth.
It’s essential to note that the specific parameters, such as the time period for the EMA or the frequency of data used, may vary based on the preferences of analysts or traders and the unique characteristics of the market under analysis.
Understanding the STIX Indicator in technical analysis
The Short-Term Index (STIX) plays a crucial role in technical analysis as it offers valuable insights into market breadth and aids in assessing the strength of a market trend. Here are some key reasons why STIX holds significance in technical analysis:
Market breadth analysis
STIX facilitates the evaluation of stock participation in a market trend, providing a breadth perspective by considering both advancing and declining stocks. By examining the ratio of advancing stocks to total stocks, STIX serves as a measure of market sentiment and overall market health.
Confirmation of trends
STIX acts as a confirming factor for trend strength. A high STIX value, indicating a greater proportion of advancing stocks, confirms a robust market with widespread participation. This validates the sustainability of an upward trend. Conversely, a low STIX value, reflecting a larger proportion of declining stocks, may confirm a weakening trend or potential reversal.
Indication of market reversals
STIX helps in identifying potential market reversals. Divergences between STIX and price movements can signify a shift in market sentiment. For instance, if prices are rising while STIX is decreasing, it may indicate a loss of breadth in the market rally, suggesting a potential market correction or reversal.
Overbought and oversold conditions
STIX aids in identifying overbought and oversold market conditions. When STIX reaches extreme high levels, it may suggest an overbought market, characterized by excessive bullishness and the possibility of an imminent correction. Conversely, extremely low STIX values may indicate an oversold market with excessive selling pressure, potentially signaling a rebound or buying opportunity.
Identifying Optimal Moments to Enter and Exit
Traders can utilize STIX as a timing tool for identifying optimal entry and exit points. By combining STIX with other technical indicators or price patterns, traders can determine favorable moments to enter or exit trades. For example, a trader may seek bullish price signals alongside a rising STIX to initiate a long position.
In conclusion, the Short-Term Index (STIX) holds great importance in technical analysis as it provides insights into market breadth, confirms trends, identifies potential reversals, highlights overbought or oversold conditions, and assists in timing entry and exit points. By considering stock participation in the market, STIX enhances understanding of market sentiment and supports well-informed trading decisions.
Some suggestions on how to use the STIX Indicator
As per findings from “The Polymetric Report”:
- Typically, the STIX value falls within the range of +42 to +58.
- When STIX drops to 45 or lower, the market is generally favorable for buying, except during a strong bear market.
- If STIX climbs to around 56, the market is relatively overbought. It’s advisable to consider selling, except in the case of a new bull market.
- It’s important for traders and investors to customize these general guidelines to align with their individual goals.
- In usual market conditions, STIX rarely reaches extremes like 56 or 45. Adhering strictly to these guidelines might result in limited actions. For active accounts, these rules could be adjusted to be less strict (refer Table below).
|Extremely Overbought||greater than 58|
|Fairly Overbought||greater than 56|
|Fairly Oversold||less than 45|
|Extremely Oversold||less than 42|
Advantages & Limitations of the STIX Indicator
Here are the advantages and limitations of incorporating the Short-Term Index (STIX) into trading strategies:
- Market Breadth Assessment: STIX analyzes the ratio of advancing stocks to total stocks, offering valuable insights into market breadth. Traders can evaluate the strength and participation of stocks in a given trend, enabling them to gauge market sentiment and make more informed trading decisions.
- Trend Confirmation: STIX provides confirmation of trend sustainability by aligning with price trends. When STIX moves in the same direction as prices, it validates the trend’s support from broad market participation, bolstering traders’ confidence in their positions.
- Early Reversal Signals: STIX helps identify potential market reversals through divergences between STIX and price movements. When prices trend in one direction while STIX moves in the opposite direction, it signals a weakening trend or an upcoming reversal. Traders can adjust their positions or capitalize on contrarian trading opportunities based on this early warning.
- Lack of Standardized Interpretation: STIX lacks a standardized interpretation or fixed threshold values. Traders may have different approaches and thresholds for interpreting STIX, resulting in subjective interpretations. This can introduce uncertainty and inconsistency when utilizing STIX as a trading tool.
- Lagging Indicator: STIX relies on an exponential moving average (EMA) calculation, introducing inherent lag in the indicator. Consequently, STIX may not provide real-time signals and can lag behind market movements, potentially causing delayed entries or exits in trades.
- Sensitivity to Timeframe and Parameters: STIX’s effectiveness is sensitive to the chosen timeframe and parameters for calculation. Different timeframes or EMA periods can yield diverse results and interpretations. Traders must carefully select appropriate parameters aligned with their trading style and market conditions to avoid misleading signals.
It’s important to note that while STIX offers valuable insights, it is advisable to supplement it with other technical indicators, risk management strategies, and comprehensive market analysis techniques to develop a well-rounded trading approach.
