Investors new to the trading market are often troubled by market charts, but in fact, as long as you learn to read candlestick charts, you can understand market trends more efficiently. This article will approach from a practical perspective, teaching you how to accurately interpret K-line patterns, identify market turning points, and avoid common trading traps.
What Exactly Are K-Lines Saying?
Candlesticks, also known as K-lines or candlestick charts, are the most fundamental and important tools in technical analysis. They condense four key price data points within a time period—opening price, highest price, lowest price, closing price—into a single bar, visually displaying the psychological changes of market participants through color and shape.
Deconstructing a K-line:
A K-line mainly consists of two parts. The rectangular part is called the “real body,” which reflects the relationship between the opening and closing prices. When the closing price is higher than the opening price, the real body appears red (bullish line), indicating buyers are in control; conversely, it is green (bearish line), indicating sellers dominate.
The thin line extending from the real body is called the “shadow.” The shadow above the real body is the “upper shadow,” representing the highest price during the period; the shadow below is the “lower shadow,” representing the lowest price. These shadows reveal suppressed market forces and often hide important trading signals.
It should be noted that different markets have different color conventions. The US stock market typically uses green for bullish lines and red for bearish lines, opposite to the Taiwan stock market.
Characteristics of K-Lines in Three Timeframes
K-lines are highly flexible in time, applicable to any period:
Daily K (Day K): Suitable for short-term traders observing price fluctuations within a few days, quickly capturing recent trends;
Weekly K (Week K): Used for medium-term trend judgment, combined with daily K to gain a more comprehensive understanding of price movements over several weeks;
Monthly K (Month K): Serves long-term value investors, showing price trajectories over months or even longer cycles, with fundamental analysis considered.
Below is an example table illustrating the difference between daily K and weekly K:

Choosing different timeframes determines your trading strategy. Short-term traders rely on minute-level changes in daily K, while value investors observe long-term battles between bulls and bears through monthly K-lines.
Five Common K-Line Pattern Quick Reference Table
K-line Type
Market Characteristics
Trading Implication
No Shadow Bullish Line
Close = Highest Price
Buyers dominate completely, prices continue to rise throughout the cycle, likely to remain strong in the future
Double Shadow Bullish Line
Shadows are equal length
Bulls and bears are evenly matched, market is stalemated, price lacks clear direction
Lower shadow > Upper shadow
Attempted rebound met with cold reception, buying strength insufficient to break resistance
Upper shadow > Lower shadow
Buyers have the advantage, gradually pushing prices higher, high probability of continued rise
Upper Shadow Only Bullish Line
Close > Open
Price surged but faced resistance and turned back, bulls still in control but attacked by bears
Lower Shadow Only Bullish Line
Close > Open
After decline, support led to rebound, bulls gradually accumulate strength, possible reversal upward
No Shadow Bearish Line
Close = Lowest Price
Sellers dominate entirely, prices decline continuously over the cycle, high risk of future decline
Double Shadow Bearish Line
Shadows are equal length
Bears control the market, bulls struggle to turn the tide, trend may continue downward
Lower shadow > Upper shadow
Rebound met with rejection, selling pressure persists, high risk of secondary decline
Upper shadow > Lower shadow
Both sides are in stalemate, price oscillates within a range, no clear direction
Upper Shadow Only Bearish Line
Close < Open
Surge faced resistance, strong bearish force, downward trend not over
Lower Shadow Only Bearish Line
Close < Open
Weak rebound, bulls retreat completely, high probability of reversal downward
K-lines may seem complex, but they are essentially a combination and collision of four prices. Instead of memorizing various pattern names blindly, understand the market logic behind them: each K-line tells a story of the battle between bulls and bears. Mastering this makes pattern recognition natural.
Principle Two: Focus on closing price position and real body size to judge market dominance
Key question: Where does the K-line close?
Implication: This determines who currently holds the market power. If the close is near the high, buyers are still in control; if near the low, sellers dominate.
A further method is to compare the current K-line’s real body size with previous ones. If the current real body significantly enlarges (more than twice), it indicates one side’s strength is increasing; if it shrinks or remains unchanged, that side’s strength is waning.
Principle Three: Track swing highs and lows to confirm trend direction
The simplest way to read K-lines is to observe major swing turning points:
Uptrend: Swing highs and lows move higher, indicating increasing buying power
Downtrend: Swing highs and lows move lower, indicating increasing selling power
Range-bound: Swing highs and lows stay at similar levels, market is stalemated
Drawing trend lines, support, and resistance lines helps clearly determine whether prices deviate from established channels.
Principle Four: Accurately identify reversal signals to lock in low-risk opportunities
Predicting market turning points is the most valuable skill in trading. Follow these three steps to improve success rate:
Step 1: Wait for price to reach support or resistance lines, observe for effective breakthroughs or pullbacks
Step 2: When the real body shrinks and trend momentum weakens, verify with volume and KD indicators
Step 3: When retracement strength reasserts, it signals to execute trading strategies
Example analysis:
When the price hovers near resistance and the trend line points downward, if the K-line turns from green to red but volume diminishes significantly, it often indicates upward momentum is waning, and a short-term shorting opportunity may arise.
Conversely, if the retracement candles enlarge rapidly, it suggests increased selling pressure; avoid rushing into trades, wait for clearer signals.
Many traders panic when prices approach resistance lines and rush to short. But when swing lows gradually rise and approach resistance, the situation is often the opposite—this indicates buyers are systematically pushing prices higher, and selling power is weak. Prices are likely to continue upward.
This pattern on the chart usually appears as an “ascending triangle,” a classic bullish signal.
Technique Two: Momentum overbought/oversold signals indicate reversal at the corner
When momentum shrinks significantly, buyers are unable to lift prices further, and prices keep falling, reducing the motivation for new buyers. The market forms a “liquidity gap,” often signaling an imminent reversal, as widespread bearish sentiment brews.
Technique Three: Recognize and exploit false breakouts
Many investors fall into the trap of false breakouts: prices break above resistance with a large bullish candle, then reverse immediately, forcing stop-losses.
The countermeasure is to first confirm the support and resistance levels of the breakout. When the price pulls back and the breakout fails, reverse trading (trading opposite to the false breakout direction) can turn risk into opportunity and achieve real profit.
Key Points Summary
✓ The composition and meaning of K-line patterns are the foundation of all analysis; deep understanding is required, not mechanical memorization
✓ Focus on the position of the closing price and changes in real body length to quickly grasp the strength of bulls and bears
✓ Trend judgment of swing highs and lows helps grasp the overall market direction and avoid being misled by short-term fluctuations
✓ When trend movement slows or retracement strength increases, it often indicates market strength is weakening; adjust strategies accordingly

Three-Step Advanced Trading Techniques
Technique One: Rising swing lows + approaching resistance = bullish strength
Many traders panic when prices approach resistance lines and rush to short. But when swing lows gradually rise and approach resistance, the situation is often the opposite—this indicates buyers are systematically pushing prices higher, and selling power is weak. Prices are likely to continue upward.
This pattern on the chart usually appears as an “ascending triangle,” a classic bullish signal.
