Ethereum's price has been showing signs of recovery in recent days, and this has led to an improvement in investment sentiment in the futures market. One of the indicators that measure investment sentiment in the futures market is the market buy/sell ratio. This ratio shows the number of buy orders compared to the number of sell orders. A high buy/sell ratio indicates that investors are optimistic about the short-term price trend, while a low buy/sell ratio indicates that investors are pessimistic. Ethereum's buy/sell ratio has increased significantly in recent days, as the price has rebounded near the $3,000 support level. This suggests that investors are becoming more optimistic about the short-term price trend. Another indicator that shows improvement in investment sentiment is the open interest in Ethereum futures contracts. Open interest is the total number of futures contracts that are currently open. A high open interest indicates that there is a lot of activity in the futures market, and this can be a sign that investors are expecting a significant price move. Ethereum's open interest has increased in recent days, as the price has rebounded near the $3,000 support level. This suggests that investors are becoming more confident in the short-term price trend. Overall, the improvement in investment sentiment in the futures market is a positive sign for Ethereum. This suggests that investors are becoming more optimistic about the short-term price trend, and this could lead to further price gains in the future. However, it is important to note that the futures market is a volatile market, and there is always the potential for a sudden reversal in sentiment. Investors should be aware of the risks involved in trading futures contracts, and they should only trade with money that they can afford to lose
