It is almost impossible to wash out retail investors completely.
As long as retail investors are still watching the market, the main force has ways to wash them out. If retail investors are not washed out to a certain extent, it will affect the main force's trading plan, which is not allowed by the main force. The main force has many tactics to wash out retail investors, and the three tactics that frustrate retail investors the most are usually effective in making them unable to remain calm.
'Grinding', a common tactic used by the main force
The grinding process can take a long time, and the price just won't rise. If it rises by 1U and falls by 2U, retail investors with little patience will be 'ground' out by the main force.
'Pit', after the 'grinding', there are still many retail investors who haven't been washed out, so the main force will dig a pit to continue washing out retail investors.
The main force digging a 'pit' will cause the price of the currency to drop rapidly, creating a sense of a breakdown with no bottom in sight. This instills fear in retail investors, making them uncertain about how much longer and how deeply the price will fall. Many retail investors have been trapped by the main force and will never have the opportunity to climb out.
The ultimate tactic 'coercion and temptation'
After experiencing the above two tactics, if the washout has not reached the main force's ideal value, the main force will resort to 'coercion and temptation' tactics to wash out again. 'Coercion and temptation' refers to the main force raising prices to test the market, allowing retail traders to break even or make small profits, encouraging them to take profits. Those who do not take profits will see the main force control the price to naturally fall, forcing retail traders to exit.
