# 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.
