Trading in the crypto space, understanding K-line patterns can help you avoid significant losses. Today, let's discuss the six most common classic K-line combinations in the market. These are all "routines" used by major players. Learning to recognize them can help you seize key opportunities.

**First: Three Yin Lines Not Breaking the Yang, Bulls Take Control**

The market is moving within an upward channel, suddenly a large bullish (yang) candle with high volume appears, followed by three retracement (yin) candles. The key is that these three yin candles do not break the low of the previous yang candle. What does this indicate? The main force's chips are very stable, and these yin candles are just shakeout moves. Once the trading volume picks up again, the price will surge upward immediately.

**Second: One Yang Swallows Three Yin, The Counterattack Horn Blows**

After three consecutive days of decline, retail investors' sentiment is basically collapsing. Just as everyone is about to cut losses, a large bullish candle suddenly appears, directly swallowing all three previous yin candles. This is not a rebound; it’s a signal of the bulls' official counterattack. Funds are re-aligning, and there’s a high chance of further action afterward.

**Third: Double Limit-Ups Clash, The Era of Wild Coins Begins**

One limit-up after another, market sentiment instantly ignites. This structure is particularly fierce in the crypto circle. It’s usually not the end of the trend but the start of a major upward wave. Many people hesitate here, only to chase higher later and end up watching others profit.

**Fourth: Long Yin Crash and Long Yang Rebound, Violent Shakeout Routine**

First, a terrifying long yin candle scares out all the indecisive traders. Immediately after, a more aggressive long yang candle recovers all lost ground. This combination means: the main force wants chips, and the door is welded shut. You can’t run even if you want to.

**Fifth: Golden Needle Bottom with Morning Star, Bottom Reversal in Sight**

Near the end of a decline, a long lower shadow or doji star K-line appears, followed by a large-volume bullish (yang) candle the next day. This indicates the bears have lost strength, and the bulls take over the dominant position. It’s a typical emotional reversal point. Paying attention to this pattern can help you catch many rebound opportunities.

**Sixth: Two Yangs Sandwich a Yin, Fake Correction and True Upward Attack**

A bullish candle rises, then a bearish candle retraces, followed by another bullish candle strengthening. This is the most common operation in the crypto circle—fake retracement, real attack. The main force clears out retail traders’ floating chips with this combo, then directly breaks through key resistance levels.

The logic behind these six patterns is: **Main players are deploying, retail investors are panicking**. Learning to recognize these signals can at least help you avoid cutting losses at the worst times. Of course, any pattern should be combined with volume and market heat; a single pattern can also be a trap for false signals. Observe more, review more, and experience will naturally come.
