A few points to note when rolling:
1. Be patient enough. The profit of rolling is huge. As long as you can roll successfully a few times, you can earn at least millions of dollars. So you can't roll easily. You have to find opportunities with high certainty;
2. Opportunities with high certainty refer to sideways fluctuations after a sharp drop, and then an upward breakthrough. At this time, the probability of trending is very high. Find the point of trend reversal and get on the train at the beginning.
3. Only roll more and don't take short.
Only give you dry goods, and you can't catch the Lai.
