After a large-scale decline at a high level, how will the market outlook generally go? We all know that the stronger buying power than selling power is the key reason why currency prices continue to rise. When the currency price is at a relatively high level, a sudden increase in volume will almost no longer be a unified buying force. Why? Because it is already at a relatively high level, institutional market makers and even retail investors do not need to use higher unit prices and larger funds to purchase and control this currency (unless there is strong good news). A large amount was suddenly released at a high level. Most of this large amount was actually a sudden increase in selling orders. The bullish forces that continued to push up the currency price were pulled back by the sudden increase in bearish power, and the currency price fell accordingly. Therefore, a large amount of decline occurs at the high level, and then it usually continues to fall. Next, the second knowledge point is: after a large increase in volume at a high level and a large decline, followed by a sudden sharp increase in volume, is this a bullish signal?
