Open any chart for $BTC or any other coin and you'll see rows of green and red bars. These are candlesticks, and they're the most popular way to show price movement. Once you can read them, a chart stops looking like noise and starts telling a story about buyers and sellers.

What one candle shows

Each candle covers a fixed period of time, such as 1 hour, 4 hours or 1 day. It shows four prices:

• Open: the price at the start of the period

• Close: the price at the end of the period

• High: the highest price reached

• Low: the lowest price reached

The thick part is the body, which runs from the open to the close. A green body means price closed higher than it opened. A red body means it closed lower. The thin lines above and below are called wicks or shadows, and they show how far price traveled before pulling back.

What the shape tells you

• Big body, small wicks: one side was clearly in control for that whole period.

• Small body, long wicks: buyers and sellers fought hard, and nobody won. This often signals indecision.

• Long lower wick: sellers pushed price down, but buyers stepped in and pushed it back up.

• Long upper wick: buyers pushed price up, but sellers rejected the move.

Four patterns worth knowing

• Doji: open and close are almost the same, forming a cross shape. It shows indecision, especially after a strong trend.

• Hammer: a small body at the top with a long lower wick, appearing after a drop. It suggests buyers are starting to defend a level.

• Shooting star: a small body at the bottom with a long upper wick, appearing after a rise. It suggests sellers are pushing back.

• Engulfing: a candle whose body completely covers the previous candle's body in the opposite color. A green engulfing candle after a decline can hint at a reversal, and a red one after a rally can hint at weakness.

Context matters more than the pattern

A single candle means very little on its own. What gives it weight is where it appears:

• At support or resistance: a hammer at a level where price bounced before is far more meaningful than one in the middle of nowhere.

• With volume: a reversal candle on high volume shows real participation. On low volume, it can be easily ignored.

• On higher timeframes: a daily candle carries more weight than a 5-minute candle, because more money and time went into forming it.

A simple way to practice

Step 1: Open a daily chart of $ETH or Bitcoin and mark the obvious highs and lows from the past few months.

Step 2: Look at the candles that formed at those levels. Notice the wicks, the body sizes and the volume.

Step 3: Scroll forward one candle at a time and guess what happens next before you look.

Step 4: Write down what worked and what didn't. Patterns become useful only after you've seen them play out many times.

Common beginner mistakes

• Acting on a candle before it closes. A candle that looks like a hammer halfway through can look completely different at the close.

• Seeing patterns everywhere. If you search hard enough, you'll find one on every chart.

• Ignoring the bigger trend. A bullish candle inside a strong downtrend is often just a pause.

• Trading without a plan. Know your entry, your exit and how much you're willing to lose before you act.

The takeaway

Candlesticks are a language. Each one tells you who was stronger during a period of time, and groups of candles show how that balance is shifting. Learn the basics, always read them in context, and they'll make every chart easier to understand.
