Oscillator Indicators: Reading Swing Position with RSI, Stoch, and CCI
In this article, we look at oscillators not as
“buy at oversold, sell at overbought” gadgets, but as tools to:
locate where the current swing sits
inside the larger trend and structure.
The main indicators in this section are:
- RSI (Relative Strength Index)
- Stoch (Stochastic Oscillator)
- CCI (Commodity Channel Index)
We also briefly introduce the Dual Momentum concept
and then move the full strategy discussion to
dual-momentum.
The diagram below compares how the same RSI levels behave:
- left: in a trending environment, and
- right: in a range-bound environment.
Understanding this difference helps you distinguish when:
- the same RSI 70/80 means
- healthy momentum within the trend, versus
- a short-term stretch at range highs, and
- the same RSI 30 means
- a buy-the-dip opportunity in trend, versus
- a bounce candidate at range lows.
1. What Are Oscillators? – Summaries of “Position” and “Speed”
Most oscillators:
- process recent price changes over N periods, and
- map them to a numeric band (for example 0–100),
to show whether recent action is:
- skewed toward the upper side (overbought), or
- skewed toward the lower side (oversold).
The key idea is:
- they are better at telling you
“where we are inside the swing” than at calling exact tops/bottoms.
So throughout this section we keep the mindset:
- use trend tools and structure first for the big picture, then
- use oscillators to fine-tune entry/exit and swing context.

2. Oscillators in Trend vs Range
The same oscillator value can mean very different things
depending on the environment.
-
Strong trending conditions
- In an uptrend, oscillators often stay in the middle-to-upper band,
and may rarely reach deep oversold levels. - In a downtrend, the opposite is true.
→ In such conditions, overbought readings are often more of a
“risk management and partial-take-profit” signal
than a “blindly fade the trend” invitation. - In an uptrend, oscillators often stay in the middle-to-upper band,
-
Range-bound markets
- Near the top of the range, oscillators repeatedly hit overbought zones.
- Near the bottom of the range, they hit oversold zones.
→ In these environments, the combo of
range boundary + extreme oscillator readings
can be a solid basis for short-term mean-reversion trades.
In short:
always ask “trend or range?” first,
then interpret the oscillator reading.
3. The Big Three: RSI, Stoch, and CCI
3-1. RSI – Swing strength and divergence
RSI is the most widely used oscillator.
It:
- compares the magnitude of recent gains vs losses,
- summarizes swing strength and speed, and
- often uses 70/30 or 80/20 as common overbought/oversold thresholds.
In practice you will often see:
- in strong trends, RSI sticking between 40 and 80, and
- late in trends, price making higher highs
while RSI peaks drop — a classic bearish divergence.
You can find a detailed treatment in
rsi.
3-2. Stoch – Strong in ranges and short-term swings
The Stochastic oscillator (Stoch):
- measures where current price sits
within the recent high–low range, and - maps that to values between 0 and 100.
Typical zones:
- above 80: upper band (overbought),
- below 20: lower band (oversold).
It excels at:
- timing short-term swings at clear range boundaries
defined in s-r.
But:
- in strong trends, Stoch can stick to the top or bottom band
for extended periods, so using it for aggressive counter-trend trades
can be dangerous.
For detailed settings and patterns, see
stoch.
3-3. CCI – “How far from the mean?”
The Commodity Channel Index (CCI):
- uses a typical price (often (High + Low + Close) / 3),
- compares it to a moving average,
- and measures how far price has deviated from that mean.
Common reference levels:
- 0 line: near the recent mean,
- +100: significantly above the mean,
- −100: significantly below the mean.
In strong trends:
- CCI may stay above zero and repeatedly spike above +100,
marking powerful impulse phases, - while in late stages, price can keep making marginal new highs
as CCI peaks fall — a form of bearish divergence.

4. Dual Momentum – Extending Oscillator Thinking to Portfolios
The term Dual Momentum sounds like an oscillator,
but it is better viewed as a portfolio and strategy framework.
Core idea:
-
Absolute momentum
- Has this asset gone up or down over a lookback period?
-
Relative momentum
- Among a group of assets,
which ones are stronger or weaker than the others?
- Among a group of assets,
In practice this often means:
- ranking coins/stocks by momentum metrics,
- allocating capital only to the top-ranked group, and
- rebalancing periodically.
Compared to chart-level oscillators:
Dual Momentum is much more about
“Where do I put my capital?”
than “Should I long/short this single chart right now?”
The full strategy treatment will live in
dual-momentum.
5. What You Should Always Check Alongside Oscillators
Oscillators work best as supporting tools.
They are much more reliable when combined with:
-
Trend context (trend vs range)
- Use trend
to classify uptrend / downtrend / range.
- Use trend
-
Swing structure
- Use swing-vs-correction
to ask whether you are in the early / middle / late part of a swing.
- Use swing-vs-correction
-
Key levels (support/resistance)
- Check whether the oscillator extreme appears
near important levels from
s-r,
or in the middle of nowhere.
- Check whether the oscillator extreme appears
-
Risk management
- Even the best oscillator setup does not justify
breaking your plan in
risk-management
regarding position size, leverage, or max loss.
- Even the best oscillator setup does not justify
6. Practical Checklist When an Oscillator Signal Pops Up
When an oscillator setup catches your eye,
run through at least these questions:
-
Trend or range right now?
-
On this timeframe, how “heavy” is this reading?
(Is it a minor blip or an extreme in the current context?) -
Is this signal occurring at a key level or in the middle of nowhere?
-
Where are we in the swing?
(Early, middle, or late per
swing-vs-correction?) -
Do stop, target, and position size
fit into my plan in
risk-management?

The key mindset remains the same:
Less focus on the raw number itself,
more on what that number means inside trend, level, structure, and risk.
