Cryptocurrency Trading with Charts: What Can a Candlestick Chart Tell You?

Why learn to read charts?

In simple terms, the price charts of BTC and other coins are like the “electrocardiogram” of the market. Those who can read the charts can identify risks in advance, while those who can't read them can only follow the trend and end up being cut. According to Dow Theory, there are three types of market trends:

• Major Trend — From a few months to over ten years
• Intermediate Trend — Weekly to Monthly Level
• Minor Trend — Lasts up to 10 days

Mastering this logic will allow you to establish a structured trading strategy.

Three Common Types of Candlestick Charts

Linear Graph (The Simplest Noob Version)

It's just a continuous curve that only shows the closing price points. It's comfortable for beginners to look at, but the amount of information is too little to see the full picture of price fluctuations.

Candlestick Chart (Japanese K-line, a standard for professional traders)

This is the core of reading charts. A single candle contains:

• Entity: The range from opening price to closing price
• Upper and Lower Shadows: The highest and lowest prices during this period.
• Color: Green (up) Red (down)

Key Details:

• Long lower shadow = After a sell-off, it indicates that someone is bottom-fishing at a low price.
• Short entity + long shadow = Bulls and bears in a stalemate, direction undetermined, cautious entry.
• Thick green body + short shadow = bull market signal, strong buying pressure
• Thick red body + short shadow = Bearish signal, strong selling pressure

Doji

There is almost no body, and both the upper and lower shadows are very long. This indicates one thing: the buyers and sellers are at a standstill. It often appears before trend reversal points.

5 Key Patterns to Recognize

1. Hammer — Bullish reversal signal

A sudden appearance of a candlestick during a downtrend: small body + long lower shadow, resembling a hammer. This indicates that the decline might have stopped, and if the next candlestick closes higher, the bottom may have been reached.

2. Hanging Man — Bearish reversal signal at the top

A small body with a long lower shadow appears during an uptrend. Don't be fooled by the name; this is a top risk signal. If the next candlestick closes down, be cautious of a reversal.

3. Shooting Star — top sees light dead

A long upper shadow + small body + short lower shadow appears in an upward trend. It looks like something falling from the sky. If the price continues to hit new highs afterwards but gets pushed back, it indicates there is pressure above.

4. Evening Star — A reversal pattern consisting of three candlesticks.

The first large bullish candle → the second small body → the third large bearish candle. This combination often appears at the top.

5. Morning Star — Three candlestick reversal

First big bearish candle → second small body → third big bullish candle. Bottom reversal signal.

Only by cooperating with indicators can we stabilize (looking at K-lines alone can easily lead to pitfalls)

Moving Average (MA)

The most basic average cost line. Common parameters: 10 days, 20 days, 50 days, 100 days, 200 days.

Golden Cross (short-term moving average crosses above long-term moving average) = Buy signal Death Cross (short-term moving average crosses below long-term moving average) = sell signal

For example, on June 19, 2021, the 50-day moving average and the 200-day moving average of BTC formed a “death cross,” and afterward, it really fell.

OBV (On-Balance Volume)

Observe the correlation between trading volume and price. When the trading volume is increasing and the price is fluctuating, the price usually needs to rise as well. This is called “gentle accumulation.”

RSI (Relative Strength Index)

Range of 0-100.

• >70 = Overbought, consider selling
• <30 = Oversold, consider buying

According to research statistics, the success rate of reverse operations after RSI confirmation at extreme values is approximately 70%.

Bollinger Bands (BB)

Three lines: middle track (20-day moving average), upper track, lower track.

• Price touches the upper band = Overheated
• Price贴下轨 = Overcooled
• Two tracks tightening = low volatility, may be about to explode

Market Depth Chart (DOM)

Real-time display of the accumulation of buy and sell orders. If buy orders significantly exceed sell orders, it indicates a bullish market; conversely, the opposite is also true. The deeper the depth, the smaller the impact of large transactions on the price.

How to minimize losses?

1. Learn to Read Charts — Familiarize yourself with candlestick patterns and key indicators.
2. Wait for Confirmation — A single signal can be misleading; only act when multiple indicators resonate.
3. Combine Multiple Timeframes — Use the daily chart to observe the trend, the 4-hour chart to find entry points, and the 15-minute chart for entering trades.
4. Strict Stop Loss — Exit immediately upon breaking previous levels, don’t compete with the market.
5. Tracking Indicator Combination — Don't just look at candlesticks; combining moving averages + OBV + RSI will double the effect.

The market is not 100%, but mastering these tools can tilt the odds in your favor. The rest depends on your psychological quality.
