Overall bearish, why I informed the brothers to go long on Ethereum. The key node in Ethereum's movement yesterday: False breakout confirmation: The 2550 resistance level lured longs and then quickly reversed. At 2568, a daily level Pinbar formed, conforming to the 'false breakout true reversal' model. Reflection on short entry: Shorts diverged from the actual high point by 12 dollars in the 2580-2616 order zone (relatively conservative). Those who aggressively went short at 2550 got hurt. Core basis for going long: A threefold volume spike appeared at 2366, with six consecutive 15-minute closing prices above 2402 (excluding single spikes). Currently, manage long positions with good defense: Profit targets look toward 2480 and 2520, and then observe the structural layout for short positions.
