Introduction to K-Line: Analysis of 11 Classic Patterns, Grasping Bull and Bear Battle Signals

In the past few years, I've been obsessed with staring at the Candlestick Chart, my mind filled with various candlestick patterns. Today, I'll simply organize it and share with everyone my personally verified “password book” of Candlesticks.

The market is a large psychological battlefield, and the K線 is a visual record of this tug-of-war between bulls and bears. By mastering these patterns, you can see more clearly what the market is really up to.

Below are the 11 most practical Candlestick patterns I've summarized, categorized by “reversal” and “continuation,” along with practical tips I've gained through real experience:

1. Bullish Reversal Pattern (Bear to Bull)

1. Double Bottom/W Bottom

• Features: The price has tested the bottom twice without breaking, forming a “W” shape, with the middle high point as the “neckline”.
• Underlying Logic: Bears have lost the strength to create new lows, and bulls are taking over.
• Practical Skills: Enter the market only after the breakout of the neckline with increased trading volume; do not rush to catch the bottom, and set the stop loss below the neckline.

7. Double Bottom/Broken Bottom Reversal

• Features: The price oscillates at a low level multiple times (more than 3 times) and eventually breaks above.
• Underlying Logic: The bears cannot break through the bottom, and the bulls are gradually gaining strength.
• Practical Skills: When breaking through, there must be volume support; otherwise, it is likely a false breakout. I have been deceived countless times.

10. Arc Cup Handle

• Feature: First form a U-shaped bottom, then a slight pullback (cup handle), and finally break out.
• Underlying Logic: The bottom of the cup indicates a lack of bearish strength, and the cup handle represents a consolidation phase.
• Practical Skills: The cup handle shouldn't be too deep (no more than 1/3 of the cup body). It should be accompanied by high volume during the breakout; if there is no volume, it's a trap.

2. Bearish Reversal Patterns (Bull to Bear)

4. Head and Shoulders

• Features: Three peaks, the middle one is the highest (head), the ones on the left and right are lower (shoulders), and the line connecting the bottoms is the “neckline”.
• Underlying Logic: Bullish fatigue, the right shoulder is weaker than the left shoulder after the head, a typical exhaustion of strength.
• Practical Skills: The pattern is confirmed only when it breaks below the neckline. When I operate, I usually set the stop-loss at the right shoulder, with the target being the distance from the head to the neckline.

8. Ascending Wedge

• Features: In an uptrend, a converging channel is formed with decreasing amplitude.
• Underlying Logic: Appears to be rising but momentum is waning, bulls are lacking follow-through.
• Practical Tips: Short when it breaks below the lower band, never try to short in a low wedge, I've lost a lot of money doing that.

3. Bullish Continuation Patterns (Continue to Rise During Uptrend)

3. Ascending Triangle

• Features: During the upward process, the lows are getting higher, but the highs are hindered by a horizontal line.
• Underlying Logic: Bullish forces are gradually strengthening, preparing to break through resistance.
• Practical Skills: When breaking through horizontal resistance, there should be an increase in volume; lack of volume indicates a false breakout. I often use the height of the triangle as a target.

5. Ascending Flag

• Features: After a rapid rise (flagpole), enters a brief downward consolidation (flag face)
• Underlying Logic: The trend continues after short-term profit taking.
• Practical Skills: If the consolidation takes too long, it becomes ineffective. I prefer to enter when breaking out of the flag, with the target based on the length of the flagpole.

4. Bearish Continuation Patterns (Continue to Decline in a Downtrend)

2. Descending Flag

• Features: After a sharp drop (flagpole), it enters a brief rebound consolidation (flag face)
• Underlying Logic: Bears are dominant, and the rebound is just a trap for the bulls.
• Practical Skills: A decrease in trading volume during consolidation is key; when I see this, I know it's a trap.

6. Descending Triangle

• Features: During the downtrend, the highs are getting lower, but the lows are at the same horizontal line.
• Underlying Logic: Bears are gradually gaining strength, and support is about to be breached.
• Practical Skills: When breaking below support, there must be increased volume; otherwise, it may just be a shakeout.

5. Direction Pending Formation (Requires Breakthrough Confirmation)

9. Rectangle Consolidation

• Features: The price oscillates between parallel support and resistance.
• Underlying Logic: Longs and shorts are temporarily balanced, both are gaining momentum.
• Practical Skills: I never guess the direction in advance, I only follow after a breakout; too many people fail by making premature predictions.

11. Expanding Triangle

• Features: Increasing volatility, higher highs, lower lows
• Underlying Logic: The market is highly divided, and extreme fluctuations are brewing.
• Practical Skills: This pattern carries a terrifyingly high risk, I usually test with small positions or simply wait and observe.

Practical Advice:

Laozi said that candlestick patterns are not a fool's guide! The money I've lost is enough to make you cry for three days and three nights. Remember the following points:

1. The major trend is your father: trying to operate against the major trend is like wanting to fly upwards while jumping off a building, don't ask me how I know.
2. Volume is more important than patterns: A breakout without trading volume is like a shell without a soul.
3. Larger timeframes are more accurate than smaller timeframes: daily and weekly charts are more reliable, while patterns observed on minute charts often turn out to be traps.
4. Always set stop-loss: Any form can deceive, setting a stop-loss is not weakness, it is the wisdom to survive.

Candlestick patterns are just tools to increase the win rate, not a money-making code. I suggest beginners start by practicing with a demo account, observing the integration of patterns, volume, and trends. Only after personally experiencing the pitfalls can one truly master it.

Remember: The core of successful trading is probability and risk control; technology is just an aid.
