Today's Ethereum short-term strategy: enter long near 3890, add position twice near 3860, if it breaks below 3820, no need to rush to close the position. Observe 2 fifteen-minute candles; if it can sustain 3 additional positions, if it breaks below 3780, exit all. If it goes up, look near 3980 to reduce position and hold, look above 4000.
