The Know Sure Thing
The KST is +50.86, above its signal line at +39.80.
- The momentum
- The KST is above zero and rising on the last bar. It has been above its signal line for 28+ bars.
- How it is read
- Above zero, the blended momentum of four time frames points up; below zero, down. Pring's main signal is the KST crossing its 9-bar signal line, best when it agrees with the side of zero and the trend.
- Read it with care
- It is built from rates of change, so it lags and whipsaws in sideways markets. It gives no timing for the next bar.
The KST, its 9-bar signal line and the gap between them on the last bars (rates of change of 10, 15, 20 and 30 bars, weights 1 to 4). The last bar is marked.

Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

Four time frames in one line
Martin Pring built the Know Sure Thing to see short and long momentum at once. It takes the 10, 15, 20 and 30-bar rates of change, smooths each with a simple average (10, 10, 10 and 15 bars), and adds them with weights of 1, 2, 3 and 4, so the slower moves count more. A 9-bar average of the result is the signal line.
