$ETH Today's optimal trading direction is to wait for a rebound to key resistance levels for shorting. The most critical moving average resistances are 30-minute MA20=2114.55 and 1-hour MA20=2131.84. If price fails to hold above 2114, the bearish structure remains intact. Entry logic: Patiently wait for price to rebound to the 2114-2132 zone (focus on 1-hour MA20=2131.84), and enter a small short position when stagnation signals appear such as long upper wicks or 15-minute RSI entering overbought territory. Stop loss is set above the 1-hour MA20, for example at 2135. If the short position is effective, the first target is the daily MA20 support at 2095, and after breaking through, the second target is the 6-hour MA200=2059.50. Risk management: This is a rebound short operation following the major downtrend, standard position sizing can be used. Pay special attention to the 2102.7 zone above the 2097.19 support level. If price breaks above this level quickly but with insufficient volume, it may be a stop loss hunt and bull trap, which could provide a better shorting opportunity instead. If price unexpectedly stands firm above the 1-hour MA20=2131.84, then the short position should exit and observe, with the upper level testing the 2160 double top neckline resistance.
