The Know Sure Thing (KST) Indicator: How to Identify Market Momentum and Trend Strength
The Know Sure Thing (KST) Indicator is a momentum oscillator that helps traders spot trend direction and strength across multiple timeframes. Developed by Martin Pring, KST smooths out price fluctuations to provide a clearer picture of market momentum.
In this guide, we’ll break down how KST works, how to use it effectively, and the best KST trading strategies.
What Is the Know Sure Thing (KST) Indicator?
The KST Indicator is based on four different Rate of Change (ROC) periods, each smoothed with a Simple Moving Average (SMA). This multi-timeframe approach helps reduce noise while capturing long-term market trends.
How to Interpret the KST Indicator:
- KST above zero → Bullish trend confirmation.
- KST below zero → Bearish trend confirmation.
- KST crossover above signal line → Buy signal.
- KST crossover below signal line → Sell signal.
How the KST Indicator Is Calculated
The KST formula combines different Rate of Change periods:
[
KST = (ROC_1 \times W_1) + (ROC_2 \times W_2) + (ROC_3 \times W_3) + (ROC_4 \times W_4)
]
Where:
- ROC_1, ROC_2, ROC_3, ROC_4 measure price changes over different periods (typically 10, 15, 20, and 30).
- W_1, W_2, W_3, W_4 are weighting factors to smooth fluctuations.
- A Signal Line (9-period SMA) is used for trade signals.
By combining short-term and long-term momentum, KST provides a more reliable trend confirmation than single-period oscillators.
How to Use the KST Indicator in Trading
Identifying Momentum Trends
- If KST is above zero and rising, the market is in a bullish phase.
- If KST is below zero and falling, the market is in a bearish phase.
KST Crossover Strategy
- A bullish KST crossover (KST crosses above the signal line) → Buy signal.
- A bearish KST crossover (KST crosses below the signal line) → Sell signal.
KST Divergence Strategy
- Bullish Divergence: Price makes a lower low, but KST makes a higher low → Potential trend reversal upward.
- Bearish Divergence: Price makes a higher high, but KST makes a lower high → Potential trend reversal downward.
Best KST Trading Strategies
KST + Moving Average Strategy
- Buy when KST crosses above the signal line and price is above the 50-day SMA.
- Sell when KST crosses below the signal line and price is below the 50-day SMA.
KST + RSI Strategy
- Buy when KST is rising and RSI is below 30 (oversold).
- Sell when KST is falling and RSI is above 70 (overbought).
KST + MACD Strategy
- Use MACD crossovers to confirm KST momentum shifts.
- If KST is rising and MACD is bullish → Strong buy signal.
- If KST is falling and MACD is bearish → Strong sell signal.
Best KST Settings for Different Trading Styles
- Day Trading: Use shorter ROC periods (5, 10, 15, 20) for quicker momentum signals.
- Swing Trading: Default (10, 15, 20, 30) settings for balanced trend confirmation.
- Long-Term Investing: Use longer ROC periods (20, 30, 40, 50) for major market trends.
Common KST Mistakes to Avoid
❌ Ignoring the signal line crossover – KST signals are strongest when confirmed by a crossover.
❌ Using KST alone – Always pair KST with moving averages, RSI, or MACD for better accuracy.
❌ Expecting immediate signals – KST is a lagging indicator, meaning it works best for trend confirmation, not forecasting.
Final Thoughts – Should You Use the KST Indicator?
The Know Sure Thing (KST) Indicator is a powerful tool for identifying market momentum, trend confirmation, and potential reversals. When combined with moving averages, RSI, or MACD, it helps reduce noise and improve trade timing.
