#EducationalSeries #MACD #RSI

There is a question that many people may not have really thought about yet: in the entire crypto ecosystem, what is the most important sector?Is it exchanges? Is it institutions? Is it data companies (DAT)?

To answer this, we first need to figure out what is truly most important to the crypto industry. The answer is very simple — liquidity. Liquidity is the most fundamental condition for every segment of the crypto ecosystem to function. The higher the liquidity of a sector, the greater its efficiency and influence. Based on this, we can conclude that the sector which carries liquidity is the most important to the crypto ecosystem — and that sector is: the secondary market.

All tokens need to circulate and be realized (cashed out) through the crypto trading market, and basically all institutions, organizations, and even retail investors are deeply involved in the crypto trading market. And once you participate in the crypto trading market, the question of how to profit from it becomes something you can’t avoid.

This is exactly the topic of today’s educational article: technical indicators in the crypto trading market. In the crypto trading market, whether you are an intraday scalper, a swing trader, or a trend follower, “technical indicators” are something you can never bypass. They are the trader’s compass, the translator of price action, and an important tool to help you reduce the interference of subjective emotions.

But most users only stay at the “I’ve heard of the names” level. They know things like RSI, MACD, Bollinger Bands, but do not truly understand the underlying logic, applicable scenarios, strengths, pitfalls, or how to combine multiple indicators into their own trading system.

In this article, we will build a systematic and complete cognitive framework for technical indicators. This is the “ultimate” tutorial on technical indicators in the SuperEx educational series — you can treat it as a mini encyclopedia.

Note: This article is mainly aimed at helping you build a cognitive framework for technical indicators, not at deeply explaining a few specific indicators.

Note: If you want to learn a specific technical indicator in detail, you can go to SuperEx Academy (https://x.superex.com/ ) to study. SuperEx Academy is the world’s first online academy to offer comprehensive education on crypto-native indicators. It features the most extensive technical indicator tutorials and is the most detailed online learning platform for market technical analysis. Here, you’ll find hundreds of courses on commonly used indicators, along with nearly every known crypto-native indicator tutorial.

What Are Technical Indicators, and Why Must Every Trader Understand Them?

In essence, technical indicators are a set of mathematical tools based on historical price and volume. Through calculations on candlesticks, trading volume, volatility, and so on, they transform price data into structured information. You can understand it like this:

• K-lines (candlesticks) = raw material
• Technical indicators = processed semi-finished products
• Trading strategies = final products

The role of technical indicators is not to “predict the future,” but to describe the current state, rhythm, strength, and bias of price, so that traders can obtain structured assistance in an information-incomplete market.

The Three Key Problems Technical Indicators Solve

1. Market Direction: Is It Going Up or Down?

For example:

• MA (moving average)
• MACD
• ADX
• Super Trend

Trend indicators help traders distinguish between trend vs. range (consolidation).

2. Market Strength: Is the Momentum Strong Enough?

For example:

• RSI
• Stochastic
• CCI

Momentum indicators reflect the strength behind the trend, helping you avoid chasing at the top or selling at the bottom.

3. Market Structure: Is Volatility High or Low?

For example:

• Bollinger Bands
• ATR

These are used to judge whether price is starting to move or ending a move through volatility.

Technical indicators do not exist in isolation — they are different dimensions of data that complement each other. Trend judgment + momentum strength + volatility structure — only when these three are combined can you form systematic trading.

The Four Major Categories of Technical Indicators

There are roughly thousands of technical indicators in the market. The system is huge and complex. However, if we classify them according to their function, then all technical indicators can be grouped into the following four categories:

1. Trend Indicators

Main purpose: identify trend direction and trend phase — in other words, the overall market direction (up or down).

• MA (Moving Average)
• EMA (Exponential Moving Average)
• MACD
• Ichimoku (Ichimoku Kinko Hyo)
• ADX (Average Directional Index)

Best for: trending markets, suitable for long-term traders or for decision points. Not suitable for: interpreting choppy/ranging conditions.

2. Momentum Indicators

Main purpose: measure the strength of price rise or decline.

• RSI
• Stochastic
• CCI
• ROC

Best for: judging overbought/oversold conditions, and spotting divergence.

3. Volatility Indicators

Main purpose: determine whether the market is about to break out and whether risk is rising.

• Bollinger Bands
• ATR
• Keltner Channel

Best for: breakout trading and risk management.

4. Volume and Capital Flow Indicators

This dimension is particularly important in the crypto market.

• OBV (On-Balance Volume)
• MFI (Money Flow Index)
• NVI / PVI (Negative/Positive Volume Index)
• Volume Profile

Best for: capturing the moves of big players and confirming trends.

In-Depth Look at 15 Mainstream Technical Indicators (Logic + Usage + Pitfalls)

Below are the most frequently used indicators in the industry — the ones that professional traders rely on the most.

1. MA / EMA — The Most Basic Trend Indicators

MA (Moving Average) is the “mother of all indicators”. The calculation is very simple, but it is the most widely used tool in trend trading.

Advantages of MA:

• Clear and intuitive
• Filters out noise
• Excellent for trend following

Disadvantages:

• Strong lag
• Easily “slapped in the face” in ranging markets

EMA increases the weight of recent prices, so it reacts faster than MA and is more suitable for highly volatile markets like crypto.

2. MACD — A Two-in-One Trend + Momentum Indicator

MACD = 12EMA — 26EMA → this gives DIF; then take the 9EMA of DIF → this gives DEA; finally, DIF — DEA → histogram.

MACD combines both trend and momentum information, and is suitable for:

• Judging trend direction
• Judging whether the trend is strengthening or weakening
• Observing divergence in the histogram

However, MACD’s biggest problem is: signals come late.

3. RSI — Momentum Overbought/Oversold Indicator

The core of RSI is: strength of upward moves vs. strength of downward moves.

• RSI > 70: strong, but possibly overbought
• RSI < 30: weak, but possibly oversold
• RSI divergence: an important signal of trend weakening

The crypto market is prone to overbought and oversold situations, so RSI is more sensitive here.

4. Bollinger Bands — The King of Volatility

Bollinger Bands are composed of three parts:

• Middle band: 20MA
• Upper band: 2 standard deviations above
• Lower band: 2 standard deviations below

They are extremely powerful:

• Use band width to judge breakout vs. contraction
• Use the bands as potential resistance and support
• Use “squeeze → expansion” to capture major impulse moves

Bollinger Bands are the foundation of all volatility-based strategies.

5. ATR — The Most Accurate Volatility Indicator

ATR does not predict direction — it tells you how big the moves are. It’s commonly used for:

• Setting stop-loss levels
• Identifying extreme conditions
• Distinguishing false breakouts from real breakouts

This is a must-use for professional traders.

6. ADX — Trend Strength Detector

ADX measures trend strength:

• ADX > 25: strong trend
• ADX < 20: ranging/choppy

It is suitable for filtering false trends and reducing blind entries.

7. Volume Profile — The Most Realistic “Position Distribution”

In the crypto market, volume itself is extremely important. Volume Profile can tell you:

• Where the main positions of big players are
• Key resistance and support levels
• High-volume nodes (value areas)

It is far more powerful than traditional “bottom-of-chart volume bars”.

8. OBV / NVI / PVI — Essential Tools for Analyzing Capital Flows

Volume-based indicators directly show whether capital is entering or exiting the market.

• OBV: add volume on up days, subtract on down days
• NVI: price changes on low volume days, representing “smart money”
• PVI: price changes on high volume days, representing retail behavior

Especially in altcoins, OBV + NVI are among the most effective tools for identifying market makers and whales.

9. Ichimoku — A Five-in-One Trend System

It includes:

• Tenkan
• Kijun
• Senkou A
• Senkou B
• Chikou

It is not just an indicator, but an entire trading system.

10. CCI, Stochastic — Representatives of the Oscillator Family

These are suitable for ranging markets:

• Judging local highs and lows
• Capturing rebounds and pullbacks
• Spotting divergence

11. VWAP — The Cost Line for Professional Traders

Widely used by institutional traders, VWAP (Volume-Weighted Average Price) reflects the average market cost.

• Price > VWAP: bulls in control
• Price < VWAP: bears in control

12–15. Less Popular but Loved by Professional Traders

• KAMA (Kaufman Adaptive Moving Average)
• T3 Moving Average
• Ulcer Index (drawdown pain index)
• Elder-Ray Index

There are many more technical indicators — you’re welcome to study them all at SuperEx Academy.

Will You Definitely Make Money Once You Learn Technical Indicators? No. Indicators Often “Lie” Too.

Why do so many people lose money using indicators? In fact, the problem is not with the indicators themselves, but with how they are used. The following 4 mistakes are made by 99% of beginners:

1. Trading with Only One Indicator

• No single indicator can describe the entire market structure.
• The correct approach: Trend + Momentum + Volatility → three-dimensional structure.

2. Failing to Distinguish Trend vs. Range

• Using trend indicators in a ranging market = guaranteed losses.
• Using oscillators in a trending market = guaranteed misjudgment.

Therefore: always identify market structure first → then choose which indicators to use.

3. Treating Indicators as “Prediction Tools”

• Indicators are not crystal balls; they are descriptive tools.
• Key point: structured information ≠ predicting the future.

4. Ignoring Volume

Many false signals can actually be filtered out simply by looking at volume.

How to Build Your Own Indicator System? (SuperEx Teaches You in 4 Steps)

A complete trading system requires: trend + momentum + volatility + risk management + capital management. Below is the most robust indicator combination framework.

1. Trend Indicator (Choose One)

• EMA 20 / 50
• Super Trend
• MACD

2. Momentum Indicator (Choose One)

• RSI
• Stochastic
• ROC

3. Volatility Indicator (Choose One)

• ATR
• Bollinger Bands

4. Volume Indicator (Strongly Recommended)

• OBV
• MFI
• NVI

5. Final Combination (Example)

For example:

• Trend: EMA moving averages
• Momentum: RSI
• Volatility: ATR
• Volume: OBV

This is a standard “institutional-grade technical indicator system.”

The Particularities of Technical Indicators in the Crypto Market (Not Comparable to Stocks)

The crypto market is very different from traditional markets:

• No daily price limit up/down
• Trades 24/7
• Extremely high volatility
• More complex institutional participation
• Faster capital rotation

Therefore, many traditional indicators need conceptual adjustment:

• RSI reaches overbought more easily in crypto
• Bollinger Bands are broken more frequently
• MACD divergence is often more effective
• Volume-based indicators are even more critical
• Trend indicators should use EMA rather than MA

This is why the crypto market must use indicator combinations that adapt to its volatility structure. Of course, there are also many crypto-native technical indicators — you can learn all of them at SuperEx Academy, where you’ll find complete tutorials on indicators designed specifically for the crypto market.

Summary (Here’s Your Final Framework)

Technical indicators are not magic formulas — they are structured descriptions of price behavior. Remember the ultimate principles:

• Do not rely on indicators to predict the future; rely on them to understand the present.
• Do not rely on a single indicator; rely on indicator combinations to reduce errors.
• Do not only look at price action; also look at capital flows.
• Do not treat indicators as crystal balls; treat them as an instrument panel.

As long as you can understand: Trend + Momentum + Volatility + Volume → you can build your own trading system.
