Quick Answer
KST is a smoothed composite momentum oscillator that combines four rate-of-change calculations into a single signal.
What Does KST Measure?
Know Sure Thing (KST) was developed by Martin Pring. It combines four different ROC calculations — each smoothed with its own moving average and weighted differently — into a single momentum oscillator. A signal line (typically 9-period SMA of KST) provides crossover entries. KST is designed to capture medium-term momentum cycles while filtering short-term noise. Bullish signals occur when KST crosses above its signal line; bearish signals when it crosses below. VaultCharts includes KST as a free subpane indicator on desktop charts.
KST = (ROC1 × 1) + (ROC2 × 2) + (ROC3 × 3) + (ROC4 × 4), each ROC smoothed with weighted moving averagesHow to Read KST
- 1KST above signal line suggests bullish momentum
- 2KST below signal line suggests bearish momentum
- 3KST crossing above zero confirms broader bullish bias
- 4Divergence between KST and price may signal trend exhaustion
