The rise in both Ether's volume and price on the daily chart indicates a healthy bullish trend, and today it has broken through the previous three major resistance points above 4000 without a quick pullback, predicting that the selling pressure near 4000 has nearly been exhausted. The next major selling pressure is near the historical high. Aggressive traders with larger positions can enter with a small amount directly (this is chasing rising prices and should be considered carefully regarding risk), managing their positions and increasing them later. Conservative traders should wait for a pullback near 4050 before entering long orders. For cautious traders, right-side trading should wait for the pullback and then for the pullback completion signal before entering long orders. On a larger scale, I am bullish; personally, I view short orders as counter-trend orders, so keep the position small and do not hold losing positions. Additionally, if today's closing price is below 4100, long orders should consider reducing positions or completely stop loss. Look for opportunities to re-enter.
