$ACT The main 48-hour and 7-day contract positions are basically dominated by short positions. This kind of pull-up has insufficient main bottom positions and no air forces. It is difficult to continue to advance relying solely on the long positions of the newly increased contracts. It will also take a period of back and forth fluctuations. Wait until the main contract long positions are sufficient before the main upward wave will begin. At this position, you can try short-term losses at the high four hours ago, but you cannot long-term shorts and take a little profit at the bottom of the range. You can stop profits in batches.
