Recently, an in-depth analysis of Ethereum's technical aspects was conducted, revealing that it has begun an upward trend. From a technical perspective, it is expected to challenge the high range of 5200-5400. However, considering other factors, this target may be somewhat optimistic.

In my personal opinion, Ethereum may first reach around 4600, and in extreme cases, it might approach the historical high. To reach the level of 5200-5400, the market needs strong momentum; although it is not entirely impossible, the probability is relatively low. A breakthrough at the 4500 point is still achievable.

For investors who have a firm belief in Ethereum, a more optimistic expectation can be held. But remember, predictions can only ever be based on probabilities. Just like a few days ago, although the technical indicators suggested a possible rise to 114, due to a misjudgment of the PPI, it actually only reached around 1125.

This experience made me realize that there is room for improvement in my abilities, and I need to constantly hone my skills and pursue more refined analysis.

When it comes to trading indicators, they are essentially public and there is nothing secret about them. Some people optimize indicators to provide long and short suggestions, even extending into quantitative trading. However, relying solely on indicator strategies is not enough because indicators are based on statistical historical data, which has a lag and cannot fully predict the future. They also cannot take into account multidimensional factors such as trading psychology, market maker behavior, position situations, and breaking news. The accuracy of purely technical analysis is about 70%, and if other factors are ignored, this ratio will be lower.

The misjudgment of the forecast made the day before yesterday stemmed from an incorrect assessment of the PPI. Relying solely on indicator strategies may lead to profits, but it is difficult to enhance one's analytical skills. Through independent analysis, even if mistakes are made, one can identify the reasons and continuously improve the trading system. While indicator quantitative strategies are convenient, they are not conducive to the enhancement of personal abilities.

Finally, remember that trading requires a two-way mindset, but the operation must be decisive. At least this is true in spot trading.
