What Is Technical Analysis in Trading

Moving Averages and Trend Identification

A 50-day simple moving average shows the average closing price across the last 50 trading sessions. It filters short-term price noise and reveals the underlying direction. The 200-day moving average is the most widely watched level in global equity markets.

When the 50-day crosses above the 200-day, traders call it a golden cross. In October 2024, Bitcoin printed a golden cross at approximately $65,000. The asset subsequently surged past $110,000, a gain of roughly 72%. When the 50-day crosses below the 200-day, traders call it a death cross, a widely watched bearish signal in technical analysis trading.

Momentum Indicators, Oscillators, and Volume

The RSI measures the speed of price changes on a scale of 0 to 100. Readings above 70 indicate an asset may be overbought. Readings below 30 may indicate oversold conditions. Backtesting across nearly 100 years of market data found that RSI and Bollinger Bands delivered the highest and most consistent win rates among the major indicators tested. 

The MACD tracks the relationship between the 12- and 26-period exponential moving averages. A crossover of the MACD line above its signal line is read as a buy signal. The ADX indicator measures trend strength on a scale of 0 to 100. Readings above 25 indicate a strong trend. Readings below 20 suggest weak or absent trend conditions, a crucial filter before applying trend-following tools.

Volume is not an oscillator. It is a confirmation tool. A price breakout on high volume signals broad market participation. The same breakout on low volume is suspect. Dow himself identified volume as a trend confirmation signal in his 1900 to 1902 Wall Street Journal editorials.

"RSI above 70 does not mean sell. It means a strong trend is running. In trending markets, RSI stays overbought for weeks."

Reading Signals Without Chart Overload

One trend indicator, one momentum indicator, and volume as confirmation. That is a complete system. Adding a fourth and fifth tool rarely improves outcomes and often creates conflicting reads, delaying decisions.

Research across 100 years of Dow Jones data confirms that combining complementary indicator types outperforms using redundant ones. Clean charts produce faster, clearer decisions. Cluttered charts produce hesitation.

Stacking a 50-day MA, a 200-day MA, RSI, and volume on a single chart gives you trend direction, trend confirmation, momentum status, and participation level. That is four distinct data points from four complementary sources. 

Key takeaway: Moving averages track the trend direction of the trend. RSI and MACD track momentum. ADX measures trend strength. Volume confirms all of them. The ADX signals a strong trend at readings above 25 and weak conditions below 20.

Technical Analysis Across Asset Classes

Technical analytics apply across markets but do not perform identically in all of them. This is the detail most introductory guides skip. Market structure, liquidity, and participant behavior all affect how reliably price levels and signals hold.

Where Technical Analysis Works Best

The global forex market traded $7.5 trillion per day in 2022, according to the Bank for International Settlements. That liquidity means price levels, trend lines, and moving averages are observed and respected by a far larger pool of participants than in smaller markets.

Research testing 497 technical trading rules across 10 currency pairs over 22 years found that these rules significantly predicted price movements in both developed- and emerging-market currencies. Simple moving averages performed best in emerging-market currencies. Oscillator-based strategies produced stronger results on developed-market currency pairs.

The Springer study of 6,406 trading rules across 41 markets found stronger outperformance in emerging equity markets than in developed ones. The reason is efficiency. More participants in a market mean price levels are tested and arbitaged more quickly, reducing the edge available from any single pattern or signal.

Limitations to Know Before Trading

The same Springer study found that technical rule predictability diminished sharply in the most recent years of the sample. Markets adapt. When enough participants follow an identical signal, the signal loses its statistical edge.

False signals are part of the process. An RSI reading of 72 does not guarantee a reversal. A head-and-shoulders pattern can form and fail. Managing position size and placing stop-loss orders at logical price levels reduces the cost of those failures. 88% of active traders already use stop-loss orders, according to industry data.

“No indicator predicted the March 2020 equity crash before it happened.”

Macro events override chart signals. Market behavior analysis has a clear boundary: it reads what markets have done. It cannot read what central banks, governments, or black swan events will do next.

Key takeaway: TA performs differently depending on market liquidity and structure. The global forex market trades $7.5 trillion daily.  Research across 22 years and 497 trading rules confirms that technical signals predict price movements in both developed and emerging currency markets.

Building a Technical Analysis Strategy

A strategy is a repeatable process with fixed rules for entry, sizing, and exit. Technical analysis basics provide the components. The strategy is how you assemble those components into a system you can test and apply consistently.

70% of active day traders report having an established trading strategy. Those who survive longer than two years are disproportionately the ones who stick to a defined process rather than switching methods after losing trades.

Combining Price Action with Indicators

Price action is raw price movement on a chart with no indicators applied. Reading price action first tells you what the market is doing. Indicators tell you how fast and how far the move is developing.

Start by identifying the trend on a higher-timeframe chart, such as weekly or daily. Move to a lower timeframe, hourly or 15-minute, to find the entry. Apply RSI to confirm momentum. Check volume to confirm participation. That four-step process is what the 30% breakout success rate in Tradeciety's trader survey was built on. 

Entry Points, Exit Points, Stop Losses

An entry point is a price level at which your analysis indicates a statistically higher probability of a move in your favor. It is a calculated decision based on pattern, level, and confirmation. It is not a certainty.

A stop-loss should be set at a price that signals the analysis was wrong. Most professional traders target a minimum 1:2 risk-to-reward ratio, meaning the potential gain is at least twice the potential loss. At a 1:2 ratio, a strategy only needs to be right 34% of the time to break even over a large sample of trades.

"A 1:2 risk-reward ratio changes everything. You can be wrong more often than you are right and still come out ahead."

Key takeaway: 70% of active traders operate with a defined trading strategy. A working strategy requires a fixed entry rule, a stop-loss rule, and an exit rule. 

Summary

What is technical analysis in investing at its core? It is a structured way to read market behavior using price and volume data collected over time. The tools have evolved since Charles Dow's 255 Wall Street Journal editorials from 1900 to 1902. 

The underlying logic has not. Technical analysis does not eliminate uncertainty. It gives you a framework for making decisions under uncertainty with rules, data, and defined risk. 89% of active traders use it because charts show things that financial statements cannot.
