Murphy's Law and Investment

firstly
The Murphy's Law, Parkinson's Theorem, and Peter's Principle are collectively known as the three most outstanding discoveries in Western culture of the 20th century.
Assuming you drop a piece of dry bread on the carpet, both sides of the bread may land on the ground. But suppose you drop a piece of bread with a layer of jam on one side onto the carpet, often with the jam on the other side(trouble). Put it another way: if something has the potential to go bad, that possibility will become a reality.
This is Murphy's Law. It has a wide range of applications and reveals a unique social and natural phenomenon. Its extreme expression is: if something bad is possible to happen, no matter how small the possibility is, it will always happen and cause the greatest possible damage.

If you want to know in advance which transactions may suffer losses, Murphy's rule can tell you:
1)Transactions that have not established protective stop loss commissions;
2)Holding excessive positions due to carelessness;
The application of Murphy's rule in the foreign exchange market:
You are afraid of falling, but it just shows you that it will fall; You hope to rise, but it doesn't rise; You can't help but sell it, and it's also starting to rise; You are optimistic about three currencies, buy one of them, and the result is that except for the one in your hand, the other two have risen very well.
Q: I am optimistic about several currencies, but when I buy one of them, everything else rises very well except for the one in my hand. What should I do?
My experience is: among the several options that I am optimistic about at the same time, I buy the one that I am most uncertain about. Or the currency that ranks last in your mind may have the best effect. The most promising thing in the currency market is also the easiest to disappoint.

1Finding the place where you lost something is the last place you look.
2If there are five trading days in a week, and the first three days are up, up, up, up, you haven't paid attention to it; The next two days, down, down. Look: Murphy's law is working!
3The banker's guillotine is also something that many people have not thought of. You can't help but think that if you bet your stock on the bank, it will one day jump. Since there is a possibility, there is an opportunity to achieve it. The merchants have been comfortable for a few years, but we didn't pay attention either. One day, we jumped into the water, and look: Murphy's law has come into effect again.
4So, this is also a probability. There are both good and bad outcomes happening every day, and the possibility of both exists simultaneously. A good result, no one pays attention. Once a bad result occurs, it is only because the result is too strong and leaves a deep impression on people that it leads to an inevitable conclusion.
In a liquid market, the bad places are where you draw conclusions, which is where the so-called Murphy's law comes into play.


Fourthly
An alternative expression of Murphy's Law:
1You travel with companions, and the less you want to be seen, the more likely you will meet acquaintances.
2If something is not worth doing, it is not worth doing it well.
3A good start may not necessarily lead to good results; A bad start often leads to a worse outcome.
4When everything is going in one direction, it's best to take a deep look in the opposite direction.
5You arrived early, but the meeting was cancelled; You arrive on time, but still have to wait; Being late means being late.
6The more things you are afraid of, the more they will appear in your life.
7"If you have the heart to plant flowers, they will not bloom; if you have no heart to plant willows, they will become shade."
8If you know the geometry you value, you will become worthless.
9If you succeed the first time, it is obvious that you have done something wrong.
10What are you afraid of, what are you coming for.
