1. Effective support:
1. During the callback process in the upward trend, the Yin K-line is weaker than the previous Yang line. Especially when it is close to the support price, the trading volume shrinks, and then the Yang line entity quickly "eats" the Yin line, and the currency price rises again.
2 A consolidation trend is formed near the support line. After a period of consolidation, Chang Yang appears, and the support line is naturally effective.
2. Invalid support:
1. During the callback process in the upward trend, the K-line frequently appears negative lines, and the strength of short positions increases. Even if it rebounds near the support line, it still shows a weak rebound.
2 A consolidation trend is formed near the support. After a period of consolidation, a long negative line appears, indicating that the support line is invalid. At this time, retail investors are rushing to flee in order to reduce losses and the price will continue to fall.
3. The currency price falls below the support line from top to bottom. Once there is a large trading volume, it means that a new wave of decline is formed.
