Know Sure Thing (KST)


Know Sure Thing (KST) is a technical momentum indicator, developed by Martin Pring, used in financial markets to analyze price trends and generate buy or sell signals. It involves the use of multiple weighted smoothed Moving Averages to determine the momentum of a specific asset. KST is commonly used by traders to identify potential entry and exit points based on trend reversals and divergences.


The phonetics for “Know Sure Thing (KST)” would be:Know: /noʊ/Sure: /ʃʊr/Thing: /θɪŋ/KST: /ˈkeɪ ˈɛs ˈtiː/

Key Takeaways

  1. Know Sure Thing (KST) is a momentum oscillator that helps identify short-term and long-term trends in stock prices by analyzing a stock’s rate of change over different periods of time.
  2. Created by Martin Pring, KST combines several smoothed rates of changes and then weights them according to the Fibonacci series to generate a single line that oscillates above and below a zero line, indicating changes in momentum and potential buy/sell signals.
  3. KST can be used as a standalone technical indicator or in conjunction with other indicators to provide more accurate entry and exit points for traders and investors. KST signals include bullish and bearish crossovers, divergences, and confirmations with other indicators.


The Know Sure Thing (KST) is an important term in business and finance, as it is a momentum oscillator that provides valuable insight into potential market trends. Developed by Martin Pring, the KST measures the price momentum of various timeframes (short-term to long-term) and creates a smooth signal to help investors identify potential buying and selling opportunities. By comparing the KST with the price action of a financial instrument, traders can spot trend reversals, potential breakouts, and overbought or oversold conditions. This ultimately enables them to make informed decisions and manage risk more effectively in their investment strategies.


The Know Sure Thing (KST) is a valuable technical indicator used primarily by traders and financial analysts for forecasting potential trends, momentum shifts, and price directions in financial markets. The primary purpose of this tool is to help investors make informed decisions by identifying ideal entry and exit points in the market, ensuring maximum profits while simultaneously mitigating risks associated with price fluctuations. By calculating the rate of change (ROC) of smoothed moving averages over different timeframes, the KST makes use of a significant amount of historical price data, ultimately providing timely insights and visualizations that aid in the decision-making process for both short and long-term investments. Implementing the KST within one’s investment strategies can help reveal critical buy and sell signals more effectively, which in turn can directly impact the efficiency of investment decisions. As the KST oscillates above and below a baseline value, it highlights periods of positive or negative momentum, making it ideal for detecting trends and possible reversals in market activity. Consequently, this invaluable indicator enables finance professionals and individual traders alike to capitalize on market opportunities by leveraging the dynamics of price movements and momentum. By incorporating the KST into a thorough investment strategy, one can better navigate the complexities of the financial landscape, ultimately achieving a more robust and optimized portfolio.


Know Sure Thing (KST) is a momentum oscillator used in technical analysis to measure long-term price trends and generate accurate buy and sell signals. Here are three real-world examples of KST in business and finance: 1. Stock Market Analysis: Traders and investors often use KST to analyze the stock market and make informed decisions on buying or selling a particular stock. For example, an investor might apply KST to the price trends of Apple Inc. (AAPL) stock. If KST indicates a bullish trend, the investor might consider buying shares, while a bearish KST signal could suggest selling or shorting the stock. 2. Forex Trading: KST can also be applied to the foreign exchange (Forex) market, where traders speculate on the fluctuating exchange rates of different currencies pairs. For example, a Forex trader may use KST to analyze the EUR/USD currency pair (Euro/US Dollar). If KST suggests an upward (bullish) momentum for the Euro against the Dollar, the trader might consider going long on the Euro, while a bearish signal could lead them to sell or short the currency pair. 3. Cryptocurrency Trading: With the rise of digital currencies like Bitcoin and Ethereum, KST has found its use in cryptocurrency trading as well. For instance, a trader might analyze the price trends of Bitcoin (BTC/USD) using KST. A bullish KST signal may prompt the trader to purchase Bitcoin, anticipating that the value will increase, while a bearish signal could indicate that it’s time to sell or short the digital currency.

Frequently Asked Questions(FAQ)

What is Know Sure Thing (KST)?
Know Sure Thing (KST) is a momentum oscillator developed by Martin Pring, designed to capture price changes and overall market trends. It incorporates smoothed rate-of-change calculations to create a more timely and accurate representation of a security’s momentum.
How is KST calculated?
KST combines four different timeframes of rate-of-change calculations, each with unique weights, and is expressed as the following formula:KST = RCM
What are the components of the KST formula?
The components of the KST formula include:1. Rate-of-change (ROC): A measure of the percentage change in price compared to a specific number of periods ago.2. Moving average (MA): A method of smoothing out price data to better identify trends.3. Weights: Assigning a multiplier to each timeframe used in the calculations to emphasize more significant timeframes.
How can traders use KST in their trading strategy?
Traders can use the KST oscillator to identify trend reversals, overbought and oversold conditions, and potential trade entry and exit points. A positive KST value indicates bullish momentum, while a negative value indicates bearish momentum. Trading signals can be generated through KST line crossovers with its moving average, as well as through divergence and convergence patterns.
How do I interpret the KST chart?
In a KST chart, the oscillator is represented as a line that oscillates around a zero line. If the KST line is above the zero line, it indicates a bullish momentum, and if it’s below, then a bearish momentum is present. The crossing of the KST line with its moving average usually helps identify buying or selling signals.
What are some limitations of the KST oscillator?
Some limitations of the KST oscillator include false signals, sensitivity to market noise, and lagging nature of moving averages. While it can provide valuable insights, traders should use KST in conjunction with other technical analysis tools and market context for a more comprehensive trading strategy.
