Complete Guide to Stock Technical Analysis Tools: Mastering 9 Key Indicators

Technical Indicator Basics: Fundamental Concepts and Applications

When investing in the stock market, analysts and traders typically evaluate stocks from two dimensions: fundamental and technical. Fundamental analysis focuses on a company's financial performance, such as key data like revenue, profit, earnings per share, and price-to-earnings ratio; while technical analysis concentrates on the analysis of price trends and trading patterns.

Technical analysis is mainly divided into two major categories:

1. K-line and Price Trend Analysis: Directly observe the changes in the shape of the price chart.
2. Technical Indicator Analysis: Auxiliary line graphs calculated using mathematical formulas, presented in line or bar form, to assist in determining market trends and trading opportunities.

Main Technical Indicator Classification and Function Details

Technical indicators can be divided into three main categories based on their functions and application scenarios: trend indicators, oscillators, and volume indicators. Each type of indicator has its unique analytical value.

trend indicators

Trend indicators are mainly used to assess and evaluate the medium to long-term direction of stock prices, helping investors predict the development of bullish and bearish situations.

Bollinger Bands

The Bollinger Bands consist of three parallel green solid lines that move in sync with the market's candlestick chart. Investors can determine market trends by observing the position of the price within the bands and the fluctuation range of the three lines.

Technical characteristics of Bollinger Bands:

• When the stock price touches the upper band, it indicates a potential overbought condition and a risk of correction.
• When the stock price touches the lower band, it indicates that it may be oversold, presenting a chance for a rebound.
• An increase in channel width indicates an increase in market volatility, while a decrease in channel width indicates a decrease in volatility.

移動平均線(Moving Average)

The moving average is one of the most widely used technical indicators in the market. Its core function is to smooth out price data and show the overall trend direction.

Key points of application for moving averages:

• The stock price is above the moving average: indicating that the current market is in a bullish trend.
• The stock price is below the moving average: indicating that the current market is in a bearish trend.
• Crossovers of moving averages of different periods: Provide potential buy and sell signals

oscillating technical indicator

Oscillator indicators calculate the fluctuations in market prices, indicating the relative high and low points of stock prices, assisting investors in identifying potential turning points and buying and selling opportunities.

Relative Strength Index ( RSI indicator )

The RSI technical indicator is presented in a clear blue curve, calculating the relative proportion of price fluctuations over a specific period, making it very suitable as an introductory tool for novice investors.

Key features of the RSI technical indicator:

• RSI > 70: Entering the overbought zone, the market may be overheated, and there is a risk of decline.
• RSI < 30: Entering the oversold zone, the market may be too cold, and there is a chance of a rebound.
• The double line crossover of the RSI technical indicator: the short-term line ( green line ) breaks through the long-term line ( red line ) to form a golden crossover, indicating a buy signal; conversely, it forms a death crossover, indicating a sell signal.

smooth moving average convergence divergence technical indicator(MACD indicator)

The MACD technical indicator combines trend tracking and momentum measurement functions by calculating the difference between exponential moving averages of different periods to assess the strength and direction of market trends.

Core components of MACD:

• DIF line ( fast line ): the difference between the shorter period and longer period EMA
• MACD line ( slow line ): the moving average of DIF
• Histogram: The difference between DIF and MACD, reflecting changes in market momentum.

When the DIF line crosses above the MACD line, it forms a golden cross, which is considered a buy signal; when the DIF line crosses below the MACD line, it forms a death cross, which is considered a sell signal.

random indicator ( KD indicator )

The KD technical indicator consists of the K value ( fast line ) and the D value ( slow line ), used to identify the relative position of stock prices within a specific range, helping investors capture potential turning points.

Key applications of the KD technical indicator:

• KD > 80: Entering the overbought area, indicating a strong market but may face adjustments.
• KD < 20: Entering the oversold area, indicating market weakness but a potential rebound may occur.
• The K line and D line intersect in the overbought area: death cross, which may be a sell signal.
• The K line and D line form a crossover in the oversold area: a golden crossover, which may be a buy signal.

Williams Indicator ( The Williams Percent Range )

The Williams indicator is conceptually similar to the KD indicator but has a narrower application range. This indicator fluctuates between 0 and 100, determining the market's overbought or oversold conditions by comparing the current closing price with the recent price range.

Commodity Channel Indicator ( CCI Indicator )

The special feature of the CCI technical indicator is that there are no clear range limits, and it is mainly used to identify overbought and oversold conditions in the market, as well as the divergence phenomenon between price and the indicator.

Application characteristics of the CCI technical indicator:

• CCI value rising: indicates that price momentum is strengthening
• CCI value decrease: indicates weakening price momentum
• CCI diverges from price trends: it may indicate a trend reversal is imminent.

True Volatility Indicator(ATR Indicator)

The ATR indicator is an important tool for risk management and stop-loss setting, mainly used to measure the magnitude of market volatility, rather than to determine market direction.

Technical characteristics of the ATR indicator:

• ATR Rising: Market volatility increases, risk levels rise.
• ATR decrease: market volatility decreases, risk level reduces
• The absolute value of ATR: can serve as a reference benchmark for setting stop-loss points.

trading volume technical indicator

Volume indicators focus on analyzing the trading activity level and capital flow in the market, reflecting the power comparison between buyers and sellers as well as market participation.

Volumes technical indicator

The Volumes indicator directly shows the changes in market trading volume and is a fundamental indicator for assessing market activity.

Key points of analysis for the Volumes indicator:

• Increased trading volume: Higher market participation may lead to more sustained price movements.
• Decreased trading volume: Market participation is declining, and price movements may lack sustained momentum.
• The relationship between price and trading volume: When the price rises, trading volume increases, confirming a bullish trend; when the price falls, trading volume increases, confirming a bearish trend.

Detailed Explanation of the Four Core Technical Indicators

In-depth Analysis of Moving Averages

The core of the moving average is to take the average price over a specific period, used to smooth out price fluctuations and identify medium to long-term trends.

Exact Calculation Formula:

N-day moving average = Sum of N-day closing prices ÷ N

The actual application of moving averages depends on the trading period of the investor:

• Day traders: tend to use 5-minute, 15-minute, or 30-minute candlesticks, along with 5-day or 10-day moving averages.
• Long-term investors: Tend to use daily candlesticks or weekly candlesticks, combined with the 20-day or 60-day moving averages.

Advanced Applications of Moving Averages:

• Golden cross and death cross formed by the crossing of moving averages of different periods
• Determining the relative position relationship between price and moving averages
• Trend strength assessment of moving average system arrangement pattern

Relative Strength Index ( RSI ) Advanced Applications

The RSI technical indicator evaluates the market's overbought and oversold conditions by calculating the relative proportion of price fluctuations over a specified period.

RSI precise calculation formula:

RSI = Average Gain over the last N days ÷ ( Average Gain over the last N days + Average Loss over the last N days ) × 100

The RSI value range is between 0-100, commonly used reference values:

• RSI > 70: The market may be in an overbought state, with a risk of a pullback.
• RSI < 30: The market may be in an oversold state, presenting a rebound opportunity.

Advanced Analysis Techniques for RSI:

• Observe the crossover signals between different period RSI technical indicators.
• Identify the divergence phenomenon between RSI and price
• Combining trend line analysis with RSI to enhance signal reliability

Smooth Moving Average Convergence Divergence Indicator ( MACD ) technical essence

The MACD combines trend tracking and momentum measurement functions, making it an extremely important composite indicator in technical analysis.

Detailed Calculation Steps for MACD:

EMA(N days = ) previous day EMA(N days × (N days – 1) + today's closing price × 2( ÷ )N days + 1) EMA(M day) = ( previous day EMA)M day( × (M day – 1) + today's closing price × 2( ÷ )M day + 1) DIF value = EMA(N days) – EMA(M days) MACD value = EMA(DIF,X) Histogram = DIF line - MACD line

The three core components of MACD:

• DIF line ( fast line ): directly reflects the changes in price momentum.
• MACD line ( slow line ): smooths the DIF line to reduce false signals.
• Bar Chart: A visual representation of the difference between DIF and MACD, reflecting the strength of market momentum.

Key Signal Patterns of MACD:

• Zero Axis Crossover: The DIF line crosses the zero axis, indicating that a trend may be about to change.
• Golden Cross: The DIF line crosses above the MACD line, indicating the formation of an upward trend.
• Death Cross: The DIF line crosses downwards through the MACD line, indicating the formation of a downward trend.
• Changes in the bar chart: The bar chart shifts from negative to positive or from positive to negative, indicating a reversal in market momentum.

( Random Indicator ) KD ### System Analysis

The KD indicator is composed of the K value ( fast moving average ) and the D value ( slow moving average ), used to assess the relative position of stock prices within a specific time interval.

KD technical indicator detailed calculation process:

RSV = ( today's closing price - N-day lowest price ) / ( N-day highest price - N-day lowest price ) * 100% K = (RSV + previous day K * )N - 1(( / N D = )K + previous day D * )N - 1(( / N

The parameter N is usually set to 9 or 14, but investors can adjust it according to their trading cycle and style.

The value range of the KD technical indicator is between 0-100.

• KD > 80: The market is in the overbought zone, and prices may face a correction.
• KD < 20: The market is in the oversold zone, and the price may rebound.

Advanced Applications of the KD Technical Indicator:

• Golden Cross: The K-line crosses above the D-line from below, especially in the oversold area ) KD < 20), which can be seen as a buy signal.
• Death Cross: The K line crosses the D line from above, especially in the overbought area (KD > 80), which can be seen as a sell signal.
• Divergence analysis between indicators and price: When the price hits a new high but the KD fails to follow, or when the price hits a new low but the KD fails to follow, it may indicate that the trend is about to reverse.
