What Is Technical Analysis?

Technical analysis is the study of historical price movements and trading volume. Traders use this information to identify patterns and assess how prices may move in the future. Unlike fundamental analysis, it focuses on market data rather than a company’s financial performance or the underlying value of an asset.

For CFD traders, technical analysis is not a way to predict the market with certainty. It provides a practical framework for planning entries, placing stop-loss orders and understanding market structure.

However, frequent trading based on chart patterns can increase costs. Each time a trader opens and closes a position, they may pay the spread, commission or other trading charges. Taking more signals can therefore raise total trading costs and increase the risk of overtrading.

This guide explains what is technical analysis, how it works, and how to use its tools while keeping trading frequency and costs under control.

Quick Takeaways

• Technical analysis uses historical market data to assess the probability of future price movements.
• Chart patterns and technical indicators do not predict the market with certainty and can produce false signals.
• Frequent technical trading can increase total trading costs because traders pay the spread more often.

Technical Analysis vs. Fundamental Analysis

The main difference is that technical analysis focuses on what is happening to price, while fundamental analysis looks at why prices may move based on economic and financial factors.

For example, if you are trading the British pound against the US dollar, a fundamental trader may analyse interest rate decisions, inflation data and political developments to assess whether the currency is fairly valued. A technical trader, by contrast, focuses on the price chart to identify whether buyers or sellers are currently in control.

Combining both approaches is a common strategy among experienced traders. They use what is fundamental analysis to decide which markets to trade, then apply technical analysis to help identify potential entry and exit points.

How Technical Analysis Works: Core Concepts

The foundations of technical analysis begin with reading price charts to identify trends, support and resistance zones, and recurring market patterns.

Before using technical indicators or more advanced tools, it is important to understand the raw price data. The most widely used chart is the candlestick chart, which shows the open, high, low and close prices over a selected timeframe. This forms the basis of what is price action-the study of price movements without using technical indicators.

Traders use support and resistance zones to identify areas where buying or selling pressure has previously emerged. When price reacts repeatedly around these levels, it can form recognisable chart patterns. These are generally grouped into continuation patterns, such as flags and pennants, which may suggest an existing trend is likely to continue, and reversal patterns, such as the head and shoulders pattern, which may indicate that a trend is losing momentum or changing direction.

In practice, horizontal support and resistance zones tend to be easier to identify consistently than diagonal trendlines. Trendlines can still be useful, but they are often more subjective because the way they are drawn may vary from one trader to another.

Common Technical Indicators

Technical indicators are mathematical calculations based on historical price and volume data. Traders use them to identify trends, measure momentum and support their market analysis.

Indicators are generally grouped into two categories:

For example, understanding what is a moving average helps traders see how it can be used to identify the direction of a trend. A moving average may also act as a dynamic support or resistance level in certain market conditions. If a 50-period moving average is sloping upwards, it generally suggests that the market is in an uptrend.

Like all technical indicators, moving averages are based on historical data and therefore lag behind current price movements. They can help confirm existing trends, but they cannot predict future market movements with certainty.

Why It Matters: The True Cost of Technical Trading

Applying technical analysis to leveraged CFDs can increase trading costs, particularly when using short-term strategies that involve frequent buying and selling. The more often you trade, the more often you pay the spread and, where applicable, commission charges.

This point is often underestimated by traders who focus only on chart signals. Short-term trading strategies, such as scalping and active day trading, often rely on technical analysis and can generate multiple trading opportunities throughout the day. Every time you open and close a position, you pay the bid-offer spread and may also incur commission charges, depending on your broker.

For example, if you target a 5-pip gain on a breakout trade and the spread is 1.5 pips, the spread alone represents around 30% of your target before other trading costs are considered. This is an illustrative example, as spreads vary between brokers and market conditions. Over time, frequent trading can cause these costs to build up and reduce overall returns.

Technical analysis also cannot eliminate execution risk. If the market gaps after a major news announcement or over the weekend, a stop-loss order may be filled at the next available price rather than the level you selected. This is why developing effective cfd trading strategies is more important than simply following indicator signals.

The Biggest Risks in Technical Analysis

The biggest risks in technical analysis come from behavioural biases, false signals and treating probabilities as certainties.

One common behavioural bias is apophenia-the tendency to see meaningful patterns in random market movements. When traders spend too much time looking for opportunities, they may begin to identify patterns that are not genuinely significant. This can lead to confirmation bias, where information that supports an existing view is given more attention than evidence suggesting the market may move in a different direction.

Another common mistake is assuming that technical signals guarantee a particular outcome. They do not. Past performance does not guarantee future results, and even well-known chart patterns, such as the head and shoulders pattern, can fail or produce false breakouts.

Technical analysis should be viewed as a tool for managing risk and assessing probabilities rather than predicting future price movements with certainty. Its value comes from helping traders make consistent decisions over a series of trades, not from accurately forecasting every market move.

Before applying any technical strategy, traders should also confirm that their broker is authorised by a recognised regulator such as the FCA, and understand their right to segregated client funds and to escalate complaints through the relevant regulatory channel.

Conclusion

Understanding what is technical analysis comes down to recognising that it provides a structured way to interpret market behaviour and help manage risk. By studying price action, trading volume and technical indicators, traders can make more informed decisions about potential entry points, exit points and stop-loss placement.

However, technical analysis is based on historical market data rather than future events. False breakouts, lagging indicators and changing market conditions can all reduce the reliability of trading signals. Successful trading therefore depends not only on technical analysis but also on sound risk management and an understanding of the trading costs that can build up over time, particularly when trading leveraged CFDs frequently.
