Technical Analysis Guide: step by step to understand its importance in trading

Technical analysis is an essential tool used by traders to make buying and selling decisions in financial markets. In this article, we will explain what technical analysis is, what its purpose is, and how it can be used to identify trading opportunities. We will also examine the fundamental principles of technical analysis, the most common chart types, and the tools used in this approach.

What is technical analysis?

Technical analysis is an approach to the study of financial markets that is based primarily on the analysis of charts of historical price and volume data of an asset. The objective is to identify patterns, trends, and signals that can help predict the future behavior of that asset and therefore an investment opportunity in the short term. s.

The purpose of technical analysis

The purpose of technical analysis is to give traders a clear perspective on the direction in which the price of an asset will move, i.e. it is used to find an investment opportunity. It is also used to determine support and resistance levels, which helps to set profit targets and stop-loss levels.

Principles of technical analysis

Technical analysis is based on three fundamental principles:

Trend Principle.

This principle holds that asset prices tend to move in trends, whether bullish, bearish, or sideways. Traders seek to identify and take advantage of these trends to make profitable trades.

Principle of repetition

According to this principle, past patterns and trends have a tendency to repeat themselves in the future. Traders use the analysis of historical patterns to predict future movements and make decisions to buy or sell assets.

Market Behavior Principle

This principle is based on the idea that asset prices are influenced by the psychology of market participants. Technical analysis examines the collective behavioral patterns of traders and how this can affect asset price

Types of charts

Charts are the fundamental tool in technical analysis, the success of technical analysis is based on the understanding of the charts and the trader’s ability to predict their evolution in a given time frame.

The most common types of charts used are:  

Line charts

Line charts are a simplified representation of prices over time. These charts are composed of dots and lines, each dot represents the closing price of an asset at the end of a specified day or time and the lines connect the dots, revealing a direction or fluctuations. This type of chart is useful for identifying long-term trends and for getting an overview of price action. However, by showing only the closing price, it does not provide information about the highs and lows reached during the period, vital information for determining points of rebound or resistance.

Bar charts

Bar charts provide more detailed price information than line charts. Each bar represents a specific time period and includes four key points: the opening price, the closing price, the high reached, and the low reached during that period. The left end of the bar represents the opening price, while the right end represents the closing price. The vertical bars extending from each end indicate the high and low. This type of chart allows analysis of volatility, price ranges, and the relationships between the opening and closing prices.

Candlestick chart (candlestick)

Candlestick charts, also known as candlestick charts, offer a more detailed visual representation of prices. Each candlestick represents a time period and shows the opening price, the closing price, the high reached and the low reached. The solid part or “body” of the candlestick indicates the difference between the opening and closing price and is colored differently depending on whether the price rose or fell during that period. The “wicks” or “shadows” of the candlestick represent the highs and lows. This type of chart is widely used because of its ability to provide detailed information about price action, reversal patterns, and market psychology.

Technical analysis tools

There are numerous tools used in technical analysis, among the most common are:

Moving averages.

They help smooth price fluctuations and identify trends by averaging prices over a given period of time.

Technical indicators

These indicators are used to analyze historical data and generate buy or sell signals. Popular examples include the RSI (Relative Strength Index) and MACD (Moving Average Convergence/Divergence).

Support and Resistance Levels

These levels represent areas on the chart where prices have bounced or stalled in the past. Traders use these levels to make trading decisions, such as setting profit targets or stop-loss levels.


Technical analysis is a valuable tool for traders looking to take advantage of opportunities in the financial markets. It allows us to analyze past patterns, identify trends, and generate trading signals. However, it is important to remember that no strategy is foolproof, and technical analysis must be used in conjunction with other approaches and proper risk management. By understanding the principles, tools, and limitations of technical analysis, you can make more informed decisions in your trading operations.
