BTC and ETH Afternoon Market Trend Analysis: As of 10/20, the current market state is clearly identified as range-bound volatility, with prices running between strong support level 108600 and strong resistance level 112000. The technical analysis shows that although a bullish reversal engulfing pattern has formed recently, indicating potential reversal signs in the market, the moving average system is entangled, with short-term moving averages trending upwards while long-term moving averages trend downwards, making the trend direction still unclear. Moreover, the trading volume has not effectively increased, indicating low market participation, and the relationship between price and volume supports the current weak volatility pattern in the market. Given that the current market is in a range-bound state, with prices obstructed by the strong resistance level 112000, and the low trading volume shows low market participation, taking a high sell shorting strategy near the strong resistance level is a reasonable choice that aligns with the current market pattern.
