1Long term unwinding. Investors who have identified a major trend (such as a bullish market) and placed their orders in a minor trend (a downward trend in the market) can first stop losing and then enter at a lower price to earn a price difference. This can also earn profits from the major trend and reduce the risk of short positions caused by the minor trend.
2Short line unwinding. If investors make a complete mistake in their judgment of the market, they should decisively close their positions to avoid further unilateral price fluctuations and greater losses. The longer short-term investors hold in a unilateral market, the greater the losses they will incur.
3Light position unwinding (also applicable to investors with large funds). That is, as the decline in the price increases, it increases the buying price and uses idle funds to lower costs, waiting for the price to rebound. Its advantage is that no matter how deep it is nested, as long as it is operated properly, it can be unlocked once there is a rebound.
