There aren't many things you can really control in trading. In fact, there are only 4 things that can be directly controlled. Three of the events were pre-trade and one was post-trade.
Before trading, you can decide:
1 What to buy.
2 What** buys.
3 When to buy.
After trading, you can decide:
1 When to sell.
Even if you own this one, you still can't control whether it should be or not, because there are many factors that affect the fluctuation of the stock price. But these 4 things are enough to give you the ability to deal with the disorderly fluctuations in the market.
The first 3 matters determine your ability to grasp opportunities, and you have the freedom to choose to wait and see or trade. Before trading, you should set up strict trading conditions. Only if these conditions are met, you will trade. If the trend doesn't meet your standards, then you just stay on the ground and wait patiently. Because no one can force you to trade.
The fourth thing determines your ability to control your risk, and you have the freedom to continue or fold. If the market risk starts to be gradually exposed, you can immediately sell the position, and no one can limit you. After selling, no matter how big the risk is, it has nothing to do with you.
Therefore, we have a big loss in investment, and we must not go outside to find the reason. Blame the regulators, the policy, the bookmakers, the listed companies, the quantification, and the short-selling power. The only way out is to find the reason from oneself and constantly optimize one's trading system. External changes that you can never control, and complaining will not help you in any way to improve your investment performance! What you can do is not to complain, change yourself, improve yourself, and actively deal with external uncertainties.
