Two tests of support at 4345 occurred in the early morning and morning, and now we are looking at the rebound situation. Short-term resistance is at 4460; if it cannot effectively break through (4-hour level), we will need to refer to the price testing support again. Support at 4435 has now risen to around 4366; if this support is effectively broken (4-hour level), we will need to refer to the key support at 4100. Currently, both 4366 and 4100 are major trend supports at the 4-hour level, and we need to focus on the support situation!
