Stochastic Oscillator (STOCH): How to Read It
The Stochastic Oscillator compares the current close with the high-low range over a recent period. It shows where price sits within that range on a 0 to 100 scale.
The formula
Common settings: 14, 3, 3
How to read it
- Readings above 80 are considered overbought.
- Readings below 20 are considered oversold.
- %K crossing %D shows short-term momentum shifts.
- Works best in sideways, range-bound markets.
- Divergences with price can hint at potential reversals.
Typical signals
- %K crossing above %D below 20 as a potential buy setup.
- %K crossing below %D above 80 as a potential sell setup.
- Bullish or bearish divergence against price.
Pitfalls to avoid
- Can stay overbought or oversold during strong trends.
- Generates many signals, some of them noise.
- Very sensitive to the chosen period.

What is the difference between %K and %D?
%K is the main line, and %D is a moving average of %K used as a signal line.
Is stochastic the same as RSI?
No. Both are momentum oscillators, but stochastic measures position within a range while RSI measures gains versus losses.
What is the slow stochastic?
It is a smoothed version of the original that reduces noise.
Works well with
Relative Strength Index
The Relative Strength Index measures the speed and size of recent gains versus losses on a scale from 0 to 100. It helps spot when a market may be stretched too far in one direction.
💪Average Directional Index
The Average Directional Index measures how strong a trend is, regardless of its direction. Paired with the +DI and -DI lines, it also helps identify which side is in control.
〰️Simple Moving Average
The Simple Moving Average adds up the last N closing prices and divides by N to create a smooth line. It filters out daily noise so the underlying direction of the trend is easier to see.
