ETH 4H Trending Coin The rebound was even stronger than expected. I went long yesterday, but due to too much noise in the small timeframe K-line, I wasn’t confident and exited halfway. Tried a short last night too. Now, if I want to go long, I can only wait for two positions: 1. The trendline, which is also the retracement of the small swing low. 2. The key support level below.
