$ETH There may be many reasons for Ethereum's recent weak performance, and one key factor may be that the selling pressure is greater than the buying pressure. As can be seen from the weekly chart, the volume during the decline is significantly greater than the volume during the rise, which usually means that sellers dominate the market, leading to a decline in prices.

When the price of Ethereum fluctuates between 2100 and 2800, many investors may choose to sell after making a 30% profit. This profit-taking behavior may cause the price to fall further. In addition, as the price rises, the gradual increase in buying has formed the so-called dense chip area, that is, the oscillating market, and investors either hold on to the end or cut their losses under pressure.

Next, let's talk about the law of trading triangles. In most markets, except for very few one-sided markets, price movements tend to follow a symmetry principle, that is, prices will show a mirror-symmetrical form within a certain period of time. This symmetry can help investors predict future price movements.

Finally, let's explore how to obtain trading information from K-line. Whether it is a Yin line or a Yang line, the part from the Yin line's lower shadow to the closing price in the trend is called a down rebound, and the lowest point at this time can be regarded as a short-term support, which means an increase in buying volume. On the contrary, the part from the upper shadow of the Yang line to the closing price is called a high-fall, and the highest point at this time is the pressure level. It is worth noting that the closing prices of the daily and weekly lines can also be used as support and pressure levels.

Take Ethereum as an example, the current price is around 263X. In the previous daily K-line trend, in the process of falling from 2728 to 2310, the lower shadow of the second Yin line was at 2650, the closing price was 2675, and the lower shadow of the third Yin line was at 2634, and the closing price was 2657. Therefore, in the rise of Ethereum, we can see that the price hit 2675 and then fell back. In the daily trend from 2150 to 2728, the 2675 Yin line of the high-fall back is the so-called pressure line.

Through this symmetrical trading principle, investors can explore and apply pressure lines and support lines for trading on their own. In actual operation, trading volume is an important reference indicator. If the trading volume is large enough, the possibility of breaking through the pressure level or support level will increase.
