I noticed that many beginner traders overlook a fundamental aspect of technical analysis: chart patterns. Among them, two models constantly come up and can really make the difference between a good and a bad entry point. I’m talking about the Double Bottom and the Double Top.

Let’s start with the Double Bottom. It’s a bullish reversal pattern, and here’s why it interests me particularly. The price drops, hits a support level, bounces slightly, then falls back to test that same level again. If the second test holds and the price rises, it’s potentially a good signal. The classic example: Bitcoin drops to $28,000, bounces to $30,000, falls back to $28,000, then starts rising again. When it breaks above $30,000 with volume, that’s usually the time to enter.

Now, the Double Top works in mirror image. Instead of a trough, you have two peaks at the same resistance level. The price rises, tests the resistance, falls back, tries again to break that resistance, fails, and finally declines. Take Ethereum at $2,500: it hits that level, drops to $2,400, tries again at $2,500 but can’t pass, then collapses. This pattern often signals a bearish reversal.

What really interests me is how to use these models practically. For the Double Bottom, you need to look at the volume. If volume increases during the second support test and the breakout upward, it’s much more reliable. The neckline is the level between the two lows, and once it’s broken with volume, you can set a profit target roughly equal to the depth of the pattern.

With the Double Top, it’s the opposite. The second peak usually shows lower volume than the first, indicating weakness. When the price finally breaks the neckline downward, you can measure your profit target using the same distance.

Japanese candlesticks are your best allies for identifying these formations. Look for a bullish engulfing or a hammer at the second bottom of the Double Bottom, or a bearish engulfing at the second peak of the Double Top. These candlestick patterns reinforce the validity of your setup.

But be careful, I’ve seen too many traders get caught by false breakouts. This is especially common in volatile markets. My advice: always wait for confirmation. Either wait for a pullback to the neckline, or verify that volume supports the breakout. Don’t rush.

Another common mistake? Misidentifying the pattern. Many confuse levels or fail to recognize the true formations. That’s why I recommend practicing first on historical data, understanding the characteristics well before risking real money.

And honestly, never rely solely on these models. Combine them with other indicators like RSI or MACD. The Double Top and Double Bottom are powerful, but they are only part of the puzzle. Use them to validate your hypotheses, not to confirm them alone.

Practice remains the best teacher. Try spotting these formations on Gate with historical charts, and you’ll quickly see how they work. Once you master these basics, you’ll gain confidence and profitability.
