BTC ETH This round of upward movement is showing signs of a 4-hour level breakdown for the first time. Keep an eye on the rebound area around 643. Right now, the 63 level is a key divergence point for range traders and trend traders. The range indicators are almost at the point where a rebound might happen again, the long-short ratio has recovered to 2, and open interest is increasing. This is due to both sides entering heavily during the decline for intense competition. For trend traders, after breaking the 4-hour support at 643, they will start shifting from long to short positions, which can also be verified through the increase in open interest. So next, shorts should watch if the rebound fails to reclaim 643, while longs should see if new lows continue to be made slowly.
