Stoch

Where price sits within its recent range via %K/%D lines; used for overbought/oversold and crossovers.

8020%K%D

How to read it

Stochastic shows where the close sits within the recent high–low range, on a 0–100 scale. Above 80 is overbought, below 20 oversold. Two lines: %K (fast) and %D (a moving average of %K).

Trading signals

A %K crossing above %D inside the oversold zone (below 20) is a common long trigger; %K crossing below %D above 80 a short/exit. In a strong trend the lines can stay pinned to an extreme — confirm with a higher-timeframe filter.

Divergence

Price/stochastic divergence — price a lower low while the oscillator makes a higher low — flags a possible bottom (mirror for tops).

Parameters

K Period is the high–low lookback; Smooth K and Smooth D smooth the two lines. Longer values give smoother, fewer but cleaner crossings.
