I've been observing for some time how many new traders don't really understand how Japanese candlesticks work, so I decided to share what I've learned about them.

It all started in the 17th century when Japanese rice market merchants needed a clearer way to visualize price movements. That's how Japanese candlesticks were born, a tool that remains essential today for analyzing stocks, currencies, cryptocurrencies, and other assets.

The interesting thing is that each Japanese candlestick tells a complete story through four key elements. First is the opening price, which is where the session begins. Then the closing price, where it ends. But what really matters is the range: the highest and lowest prices the asset reached during that period. These four data points together form the structure of each candle.

Now, interpreting Japanese candlesticks is easier than it seems. If the close is above the open, the candle is bullish, usually green or white. If the opposite occurs, it is bearish, colored red or black. The body of the candle shows the strength of the move, while the upper and lower shadows reveal volatility and reversal attempts.

I have seen patterns that repeat constantly. Let's take the hammer, for example: it is a candle with a small body but a very long lower shadow that appears after prolonged declines. This generally indicates that buyers are returning to the game. The opposite would be the hanging man, which forms in uptrends and suggests that sellers are gaining ground.

Another pattern that has been useful to me is the bullish engulfing. It consists of two candles where the first is slightly bearish and the second, much larger, completely engulfs the previous one. When you see this, it usually signals a strong shift in sentiment upward. Its counterpart, the bearish engulfing, works the other way: a large bearish candle engulfing a small bullish one, indicating a downward reversal.

Why Japanese candlesticks matter so much in trading is obvious when you think about it. The size of the body tells you how strong the momentum was. Long shadows reveal volatility and points where the price was rejected. These patterns help you identify zones where the market could reverse, which is crucial for making entry and exit decisions.

What I value most about Japanese candlesticks is that you don't need complicated indicators to start using them. Just understanding these basic patterns and practicing a little can significantly improve your market reading skills. It is a tool that has lasted over 300 years for a reason: it works.
