What is effective support? In the situation of bottom consolidation, there will be many chips that are eager to buy bamboo shoots and choose to sell them as soon as the price rises slightly, so it is often very bumpy and must fall back after the rise.
So what is effective support? It means that when the price rises, it will naturally fall back, the trading volume does not break the previous high, and the low point does not break the previous low.
In this case, as long as the volume is increased again, it can effectively break through.
