BTC and ETH Market Analysis for Saturday: As of 9/27, the current market shows a clear range fluctuation pattern, with prices hovering around the key support level of 108566. The technical analysis indicates that although a bullish engulfing pattern has appeared, suggesting some rebound potential at the support level, the bearish arrangement of the moving averages and the overall weak trend limit the strength of the rebound. Moreover, the price fluctuations near the middle band of the Bollinger Bands further confirm the market's lack of clear direction. Overall, both technical indicators and external environment point towards a high likelihood of the market maintaining a range fluctuation in the short term. It is crucial to pay attention to the stability of the key support level of 108566 and the subsequent strength of the rebound. Given that the current market is in a range fluctuation state ( major premise ), and the price is near the resistance range of 111034-111659.8 with a high technical intensity ( minor premise ), a strategy of high selling near the resistance level to engage in shorting is suitable for the characteristics of a fluctuating market. BTC: Entering around 109800-110500 with a short-term target near 108000 and a long-term target near 105000, defending at 111000.
