M-top/W-bottom: Entry Timing and Principle Tutorial M-top/W-bottom, Also known as double top/double bottom, is a common reversal pattern formed by two similar highs or lows. Generally, the trading volume of the second high/low is slightly lower than that of the first. The top movement of DASH is a textbook example of an M-top breaking the neckline, retesting the neckline, and continuing to drop, perfectly aligning with our trading criteria: entry logic and stop-loss. A similar pattern also appeared in Ethereum's smaller-scale structure a few days ago. Being able to identify these types of structural patterns and combining them with strategies will make our trading even more powerful.
