Key Points
- The stochastic oscillator is a momentum indicator that compares the current close to the recent price range, helping you see momentum cycles.
- Stochastic overbought oversold levels are commonly: above 80 is overbought and below 20 is oversold, but these levels behave differently in trends.
- Stochastic is often most useful in sideways markets and ranges, where momentum swings tend to repeat more cleanly than in strong trends.
- How to use stochastic oscillator: look for momentum shifts, crossovers, and whether the oscillator can leave extreme zones with follow-through.
- Stochastic indicator settings: the common default is 14, 3, 3 and beginners should start there for consistency before adjusting.
- Stochastic RSI vs stochastic oscillator are not the same tool… Stochastic RSI measures RSI’s position in its own range, while stochastic oscillator uses price range.
- If any terms feel unfamiliar, use the Crypto Glossary for quick definitions, then return to this lesson.
Quick Answer
The stochastic oscillator is a momentum indicator that shows where the current price close sits relative to the recent high to low range, producing a value between 0 and 100. Stochastic overbought oversold levels are commonly 80 and 20, but in crypto strong trends can keep stochastic pinned in extremes, so it works best with market context. A common way to use stochastic is to watch crossovers and whether stochastic exits an extreme zone, then confirm with trend direction and key support and resistance.
Where This Lesson Fits
Lesson 17 explained RSI divergences and how to spot momentum disagreement between price and RSI without forcing signals. Lesson 18 builds on momentum work by introducing the stochastic oscillator, which is often used to read momentum cycles in ranges and to spot when a move may be losing steam.

What Is The Stochastic Oscillator?
Stochastic measures where the current close sits within the recent trading range.
If price is closing near the top of the range, momentum is stronger. If price is closing near the bottom of the range, momentum is weaker.
Stochastic oscillator definition:
- it compares the current close to the recent high to low range
- it outputs a value from 0 to 100
- it often uses two lines, %K and %D, which create crossover signals
It is a range-based momentum tool, not a trend tool by itself.
Stochastic Overbought Oversold Levels
These are the common reference levels.
Stochastic levels are often read as:
- above 80, overbought
- below 20, oversold
But overbought does not mean “must reverse”. Oversold does not mean “must bounce”.
A better interpretation is:
- above 80 suggests momentum is strong and stretched
- below 20 suggests momentum is weak and stretched
How To Use Stochastic Oscillator In Crypto
Stochastic is best used with a simple process.
1) Identify The Market Environment First
Stochastic tends to behave best in ranges.
That reaction can come from:
- sideways conditions where price swings repeat
- pullbacks in trends where momentum cycles down then resets
In strong trends, stochastic can stay pinned in extreme zones for longer than beginners expect.
2) Use Stochastic As A Momentum Cycle Tool
In a range, price often moves from support to resistance and back again.
Stochastic helps you see when momentum is cycling from low to high and back.
Mark:
- range support and resistance
- whether stochastic is moving from under 20 back above it
- whether stochastic is rolling over from above 80 back below it
3) Use Crossovers As A Confirmation, Not A Trigger
Stochastic has two lines that cross.
Stochastic crossover strategy crypto idea:
- bullish crossover when %K crosses above %D
- bearish crossover when %K crosses below %D
Crossovers are common. What matters is where they occur.
A simple filter is:
- crossovers near support matter more than crossovers in the middle of the range
- crossovers near resistance matter more than crossovers in the middle of the range
4) Watch Whether Stochastic Can Exit Extremes
A useful clue is whether stochastic can leave an extreme zone.
If stochastic is below 20: can it push back above 20 and hold?
If stochastic is above 80: can it drop back below 80 and continue?
The exit and follow-through often matters more than the “touch”.
Stochastic Indicator Settings
Most platforms default to 14, 3, 3.
Stochastic indicator settings explained:
- the first number sets the lookback window
- the second and third numbers smooth the lines
Beginners should start with defaults so you can learn the behaviour and compare across charts.
If you change settings, do it because you want a slower or faster oscillator for a specific timeframe, not because you want to fit history.
Stochastic RSI Vs Stochastic Oscillator
These are related, but not identical.
Stochastic oscillator: uses price, comparing the close to the recent price range.
Stochastic RSI: uses RSI, comparing RSI to its own recent range.
Stochastic RSI is usually more sensitive and can swing harder, which can be helpful, but also noisier.
For most beginners, stochastic oscillator is the better starting point.
Common Stochastic Mistakes
- treating overbought as an automatic sell signal
- treating oversold as an automatic buy signal
- using stochastic without key support and resistance zones
- applying it blindly in strong trends where it can stay extreme
- reacting to every crossover without context
A simple rule is: stochastic works best when you know whether you are in a range or a trend.
Mini FAQs
What is the stochastic oscillator in crypto?
It is a momentum indicator that measures where the current close sits within the recent high to low range, producing a value from 0 to 100.
What are stochastic overbought oversold levels?
Common levels are above 80 for overbought and below 20 for oversold, but these can persist in strong trends.
How do you use the stochastic oscillator?
Use it to read momentum cycles, especially in ranges, and watch crossovers and exits from extreme zones, confirmed with key support and resistance.
What are the best stochastic indicator settings?
Many traders use 14, 3, 3 as default. Beginners should start there and only adjust settings to match timeframe and desired sensitivity.
What is stochastic RSI vs stochastic oscillator?
Stochastic RSI applies the stochastic calculation to RSI values, making it more sensitive. Stochastic oscillator applies it directly to price range.
Does a stochastic crossover strategy work in crypto?
Crossovers can help confirm momentum shifts, but they work best near key levels and are less reliable without market context.

Next, Lesson 19 covers double tops and double bottoms, two classic reversal patterns that help you recognise when price fails to break a level and momentum starts to shift.
