I’ve been noticing for a while that many people who are just starting trading don’t really understand how Japanese candlesticks work, so I thought it would be useful to share what I’ve learned about it.

Japanese candlesticks are basically the most visual way to understand what’s happening with prices. They were born in Japan hace siglos when rice traders needed a way to read the market, and honestly, they still remain one of the most effective tools we have today. What’s interesting is that with just a glance at the pattern a candlestick forms, you can grasp in seconds what happened during that trading period.

Each Japanese candlestick has four key pieces of data: where the price opened, where it closed, what the high was, and what the low was. That’s all you need. With those four points, the candlestick tells you the whole story of the move.

Now, candles come in two “flavors”: bullish and bearish. If it closes higher than where it opened, it’s bullish (generally green). If it closes lower, it’s bearish (generally red). It sounds simple, but when you start combining multiple candles and see the patterns that form, that’s where Japanese candlesticks really help you make decisions.

There are some patterns that show up again and again. The hammer, for example, is a candlestick with a small body but a long lower tail. When you see it after a decline, it generally means that buyers are taking control again. Then there’s the hanging man, which looks similar but appears after an upward move, and usually means a correction is coming.

What fascinates me is how engulfing patterns work. A bullish engulfing pattern is when a small bearish candlestick is completely engulfed by a larger bullish candlestick the next day. That normally indicates there’s a strong shift in market sentiment.

Say you’re looking at a chart and you see a stock has been falling for days. Suddenly, a hammer appears. That’s generally a good sign that the downtrend is running out of steam. I’ve seen this many times in the mercado de divisas as well: a bullish engulfing pattern shows up, and prices rise because buyers took control after a period when sellers were dominating.

What’s valuable about Japanese candlesticks is that they give you clear information about three things: momentum (based on the size of the body and the shadows), volatility (how big the range of the move was), and potential points where the trend could reverse. That’s pretty powerful when you think about it.

The reality is that understanding Japanese candlesticks is like learning the language of the market. It’s not perfect, but it’s a tool that has worked for hundreds of years and is still relevant. If you want to improve your technical analysis, mastering this topic is essential.
