What Is Technical Analysis?
Technical analysis is the practice of using historical price and volume data to forecast future price movements. Unlike fundamental analysis, which examines an asset’s underlying value, technical analysis focuses on charts and statistics to identify patterns and trends【23783177852342†L330-L347】. The core assumption is that all available information is already reflected in the market price, so studying price action itself can reveal opportunities.【23783177852342†L401-L407】
Technical analysts use two broad categories of tools: chart patterns and technical indicators. Chart patterns are visual formations (like triangles or head‑and‑shoulders) that suggest where prices might move next【23783177852342†L409-L416】. Technical indicators apply mathematical formulas to price and volume data to generate signals. Most traders combine several tools to confirm potential entry and exit points【23783177852342†L360-L367】.
Common Technical Indicators
Moving Averages
A moving average smooths out price data by taking the average price over a specific period (for example, 20 days). Simple moving averages (SMAs) give equal weight to each data point, while exponential moving averages (EMAs) emphasize more recent prices. Traders often overlay two moving averages of different lengths and watch for crossovers: when a shorter moving average moves above a longer one, it can indicate upward momentum; when it drops below, it may signal a bearish trend. Moving averages are the most common technical indicators because they make trends easier to spot【23783177852342†L420-L423】.
MACD (Moving Average Convergence/Divergence)
The MACD is a momentum oscillator that compares two EMAs of different lengths to gauge trend strength. It is calculated by subtracting a longer‑period EMA from a shorter‑period EMA. A signal line — itself an EMA of the MACD — is plotted on top, and a histogram shows the difference between the MACD and the signal line. Traders watch for “signal‑line crossovers”: when the MACD line crosses above its signal line, it may indicate a bullish shift; a cross below could suggest bearish momentum. Standard settings use 12‑, 26‑ and 9‑period EMAs【444043746761743†L152-L171】.
RSI (Relative Strength Index)
The RSI is a popular momentum oscillator introduced by J. Welles Wilder Jr. It measures the speed and magnitude of recent price changes and oscillates between zero and 100. Readings above 70 typically indicate an asset is overbought, while values below 30 suggest it is oversold【473956463389719†L360-L392】. Traders often look for the RSI to cross back below 70 (from an overbought condition) or above 30 (from an oversold condition) as potential reversal signals【473956463389719†L390-L394】.
Combining Indicators and Recognizing Limitations
No single indicator is perfect. Many traders combine moving averages, MACD, RSI and chart patterns to build a more complete picture of market dynamics. Technical analysis also works best when combined with sound risk management. Remember that these tools are based on past price action, and past performance does not guarantee future results 【23783177852342†L394-L397】. Markets can behave unpredictably; therefore, technical signals should be used alongside other research and a clear trading plan.
Conclusion
Technical analysis empowers traders to make data‑driven decisions by interpreting price charts and statistical indicators. By learning the basics of moving averages, MACD, RSI and chart patterns, you can begin to understand market psychology and spot potential entry and exit points. As with any trading strategy, discipline and continuous learning are key. Use technical analysis to complement other research methods, manage your risk carefully and stay adaptable as market conditions evolve.
