The analysis of MACD in Chan Theory indeed doesn't deviate too much; even from a mathematical perspective, if the derivative of the 4-hour candlestick wave is zero, it still needs to consolidate here before restarting the upward trend. Moreover, there is also another possibility that it continues to decline, so the conclusion is that when the 4-hour candlestick derivative is zero, the next movement will be consolidation or decline. However, I still hold my view that there isn't much profit margin in shorting ETH at this position. I plan to wait for a retracement to the appropriate level before mainly going long.
