Pring's Know Sure Thing (KST)
The Pring's Know Sure Thing (KST) indicator is a momentum oscillator based on the smoothed rate-of-change for four different timeframes. Pring frequently applied trend lines to KST. Although trend line signals do not occur often, Pring notes that such breaks reinforce signal line crossovers.

Formula
The indicator formula utilizes four different time frames to show overall momentum, and not just momentum over one specific timeframe:
- ROCMA1 = 10-Period SMA of 10-Period Rate-of-Change
- ROCMA2 = 10-Period SMA of 15-Period Rate-of-Change
- ROCMA3 = 10-Period SMA of 20-Period Rate-of-Change
- ROCMA4 = 15-Period SMA of 30-Period Rate-of-Change
\[ KST Line = (RoCMA1 \times 1) + (RoCMA2 \times 2) + (RoCMA3 \times 3) + (RoCMA4 \times 4) \]
Signal Line = 9-period SMA of KST
where, SMA stands for Simple Moving Average and ROC stands for Rate-of-Change.
