Indicators and Signals — Understanding Technical Analysis Indicators
This lesson will systematically introduce the principles and applications of common technical indicators, including trend, momentum, and volatility indicators, helping you identify buy and sell signals in the market and improve the scientificity of your trading decisions.
Why Use Technical Indicators
Technical indicators are mathematical tools derived from historical price and volume data, used to assist traders in judging trend direction, market strength, and potential entry and exit points. In highly volatile crypto markets, relying solely on "feelings" or "intuition" is often unstable, whereas indicators help us extract valuable information from chaotic price movements.
The greatest value of indicators lies in:
Providing quantitative signals to make decisions more objective;
Helping identify trends and reversals;
Assisting in judging overbought and oversold market conditions;
Confirming price trends or discovering divergence signals.
However, indicators are not "predictive tools," but "reactive tools." They reflect past market behavior and current strength, not certain future movements. Understanding this is the first step in using indicators.
Classification of Indicators
Based on calculation logic and purpose, technical indicators can be roughly divided into three categories: trend, momentum, and volatility. Each has its core functions and applicable scenarios.
1. Trend Indicators
These indicators are used to determine whether the market is in an upward, downward, or sideways trend. Representative indicators: Moving Average (MA), Exponential Moving Average (EMA), MACD (Moving Average Convergence Divergence).
Moving Average (MA): Smooths out price fluctuations by averaging prices to identify trend direction.
Figure 1
Price above the moving average → Bullish trend;
Price below the moving average → Bearish trend.
Common combinations: MA5, MA20, MA60.
MACD: Calculated from two exponential moving averages, used to identify trend strength and reversal signals.
Figure 2
DIF line crossing above DEA → Buy signal;
DIF line crossing below DEA → Sell signal.
The MACD histogram (green and red bars) represents momentum strength; enlarging red bars indicate increasing upward momentum.
2. Momentum Indicators
Used to measure the speed of price increases or decreases, judging whether the market is "overheated" or "oversold." Representative indicators: RSI (Relative Strength Index), Stochastic.
RSI: Ranges from 0 to 100.
Figure 3
RSI > 70 → Overbought, potential pullback;
RSI < 30 → Oversold, potential rebound.
RSI is not a standalone decision signal but an auxiliary tool for assessing sentiment and momentum.
Stochastic: Measures market momentum by comparing the current closing price to recent price ranges.
K line crossing above D line → Short-term buy signal;
K line crossing below D line → Short-term sell signal.
3. Volatility Indicators
Used to measure the amplitude of market price fluctuations and uncertainty. Representative indicator: Bollinger Bands.
Figure 4
Bollinger Bands: Consist of a middle band (moving average) and upper and lower bands (standard deviations).
Price touching the upper band → Market may be overheated;
Price touching the lower band → Market may be oversold;
Widening bands → Increased volatility;
Narrowing bands → Market entering consolidation.
How to Combine Indicators
In practice, a single indicator often cannot provide comprehensive signals. Skilled traders enhance judgment accuracy by combining multiple indicators. Common combinations include:
Trend + Momentum
Trend indicators determine direction (e.g., MA, MACD).
Momentum indicators confirm strength (e.g., RSI, Stochastic).
Example: When the price is above MA60 (uptrend), and RSI rises from 40 to 60, it indicates increasing upward momentum, suggesting a long position.
Trend + Volatility
Trend indicators judge direction;
Volatility indicators assess risk and entry points.
Example: During an uptrend, a pullback to the Bollinger Band lower band with shrinking volume indicates a relatively low-risk buying zone.
Multi-timeframe confirmation involves verifying signals across different periods:
Daily trend upward + 4-hour MACD golden cross → Medium-term confirmation;
Hourly RSI oversold rebound → Short-term entry signal.
The core idea of combined indicators is complementarity, not redundancy. Avoid using two similar indicators (e.g., MACD and double moving averages), as signals may become redundant.
Pitfalls and Misconceptions of Indicator Signals
Over-reliance on indicators: Indicators are derivatives of price, reflecting past information. Excessive dependence on them while ignoring market structure (support levels, trendlines) can lead to a "lagging trap."
Ignoring market context: RSI overbought does not always mean a decline. In strong trending markets, RSI can stay high for a long time. Therefore, all signals must be judged in conjunction with trend direction, not used in isolation.
Using too many indicators simultaneously: Many beginners like to open dozens of indicators, resulting in conflicting signals that are hard to interpret. It is recommended to use at most 2-3 indicators: one trend, one momentum, and one volatility indicator.
Ignoring volume confirmation: Volume is key to validating indicator signals. Without volume confirmation, the reliability of any indicator signal diminishes.
Practical Case: BTC Indicator Signal Analysis
Figure 5
At a certain stage in 2025, BTC breaks through $70,000 from $60,000:
MA20 crosses above MA60, forming a "golden cross";
RSI rises from 50 to 68, indicating increasing momentum;
Bollinger Bands upper band widens, showing increased volatility.
The overlay of these three signals indicates: the market is in a strong upward trend, suitable for phased building or trend-following. Conversely, when RSI exceeds 75 and MACD shows divergence (price makes a new high but indicator does not), it signals waning momentum and warns of a potential pullback.
How to Build a Personal Indicator System
Every trader should develop an independent indicator system based on their time frame and risk appetite.

The key is not "more indicators," but "clear logic." A good system enables you to know what to do, what to wait for, and what to avoid in any market condition.
