On the way to send my children to school today, I happened to pass by a basketball court and saw someone playing basketball. The child said he likes football but not basketball. I asked why? He said that because the football goal is big and it is easy to score, but the basketball frame is too small and it is difficult to score, so he prefers football to basketball. It does seem to make sense at first, but when you think about it more carefully, you can hear the problem.
According to FIFA standards, the standard size of a football goal should be 7.32 meters long and 2.44 meters wide, 7.32×2.44=17.86 square meters.The diameter of the basketball hoop is 45 cm. Based on the diameter, the area of the basketball hoop can be calculated =π*45/2²≈1589.63cm²=0.1589 square meters, 17.86÷0.1589=112.39. So through calculation, we can understand that the area of the football frame is approximately 112 times that of the basketball frame.
If you only look at the data of the size of the ball frame and judge through simple intuitive feelings, it will indeed make people think that it is easier to score goals in football than in basketball. But in actual games, we can usually see that if both sides of a football game can score about 3 to 5 goals in total, it is considered a game with a large number of goals, while an ordinary basketball game in the NBA The two sides often exceed 100 goals combined.
So the conclusion is that it seems that the football goal frame is more than 100 times larger than that of basketball, but the actual number of goals scored is only a fraction of that of basketball.
Back to investing, why do so many people in the market like to do short-term trading? From the perspective of immediate gratification, if you just let the stock rise and fall without doing any operations, it will make people feel very frustrated. Frequent transactions will make people feel like they are working hard. It is possible that through such frequent transactions, , will not increase profits, but at least it will feel better than doing nothing.
I once heard of a survey, which was probably about someone doing a survey on the scoring route of the ball during penalty kick matches in the European Football League. The number of goals scored on the left, right and middle of the goal is about 1:1:1, that is It is said that if a goalkeeper stands still in the middle, there is a 1/3 chance of saving the ball, but through research, it is found that more than 90% of goalkeepers pounce to the left or right. When the research staff asked these goalkeepers why they pounced to the left and right, most of their answers were that it was very frustrating to stand still and not seem to make any effort.

After all, the transaction is just a point, just a hitting point. The football goal frame is indeed big enough, but there are 10 players and a goalkeeper standing in front of it. You have to pass, cooperate, pick and roll, intersperse, pass, etc. in front It takes a series of actions to give you a chance to hit the ball, and even if you have the chance, you may not be able to score. The more familiar you are with the previous series of actions and the more you train them, the more opportunities you have to hit the ball and the greater the probability of scoring a goal.
It is better to invest in silence than to move, but silence does not mean waiting quietly and doing nothing. While waiting, you should continue to study and study, slowly cultivate your own internal skills, and then wait for the opportunity to act when the opportunity arises.
