#ETHFI Break through the 4-hour trend line, retest without breaking the trend line, and predict the following trends: 1. Direct upward trend. 2. Fall along the 4-hour trend line, then either rise or fall below the trend line. 3. If it falls below the trend line, observe whether it will fall below the purple support line. If it does not fall below, it will continue to follow the upward trend. 4. If it falls below the purple support line and closes with a bearish line, the subsequent trend will be bad, quickly stop loss and exit, otherwise it is a false break and continue to hold.
