There are levels of buying and selling points. When the energy of the large level is not exhausted, a small-level buying and selling point triggers the continuation of the large-level trend, which is the most normal. But if a small-level buying and selling point is in the opposite direction of the large-level trend, and the large-level trend has no exhaustion, participating in the small-level buying and selling points at this time means taking the risk of the continuation of the large-level trend, which is a typical knife-edge licking blood.
Frequent buying and selling is not required in the market. To beat the market, what is needed is accuracy, not buying and selling frequency. Only exchanges like to buy and sell at high frequencies.
