SENS is a medical technology company that focuses on developing and manufacturing long-term, implantable continuous blood glucose monitoring systems for diabetes patients. I have been holding SENS since June 2021, and I am also bullish on SENS' products. Regardless of its ups and downs, I hope to make a profit when its next-generation product is approved.
On February 11, 2022, SENS obtained approval from the U.S. Food and Drug Administration for the next-generation Eversense E3CGM system. However, the stock price plummeted on that day. A stock that had been profitable for a long time turned into a loss, which is truly ironic. Reflecting on my trading strategy, I realized that I haven't established a profitable trading system for stocks, nor have I pre-planned a profit-making strategy. Of course, I haven't set up stop-loss and take-profit plans, which has caused the stock to become a loss instead of a profit. SENS also made me realize that having confidence in a company does not mean blindly holding it at all costs. A good company may not necessarily be a good investment symbol. And it is even more unwise to rely on news and fantasize about the stock price...

$Tesla (TSLA.US)$Near the close of trading on Friday, I watched a sad and exhilarating conversation in the wolves. The content is roughly as follows: protagonist A's own judgment on the point of a stock is very correct, but he does options, and when trading options, he not only needs to judge the right position, but also needs to cooperate with time (please forgive me for my ignorance of options. I can only express to such an extent, if the statement is wrong, please forgive me). He himself lost more than twenty thousand dollars in the deal. But instead of being depressed, he shared the example and worked with other friends in the group to find out the mistakes made in the deal. Other friends also gave their own opinions. Many of them are long responses, and the discussion lasts for more than 5 hours.
As mentioned above, I don't know anything about options, so I can't understand their conversation, but from their attitude of reply to the discussion, we can see that everyone has more or less found something to improve their trading theory in this transaction.
Although it has been more than 24 hours, it continues to give me encouragement. It is believed that many investors will have a hard time in 2022. At this moment, I even feel that the encouragement brought to me by this matter is even more precious. So this morning I wrote down the following words to encourage:
Don't let any difficulties stop you from pursuing your dreams. Perfection comes from release, not repression. Whose life does not have haze, who does not have defects and deficiencies. But you know, it is always the shadow that highlights the light, and it is often the one that can make us.

$Amazon (AMZN.US)$
Amazon's strong upward attack on Friday brought a glimmer of life to a market that is neither above nor below. Will the bull market return like this? No one knows this. Personally, I think it's better for Amazon to follow the mobile take-profit strategy when the next strong pressure level is 3,300.
In times of market instability, mindful study is also a strategy. Keep studying with my “mentor” as she interprets the Wall Street Master's JESSE LIVERMORE LEGENDARY TRADING BOOK. The reason I put quotes on my mentor is because he doesn't know me at all and doesn't know I have a student like me, but that doesn't affect me in any way by watching his videos to learn from Master JESSE LIVERMORE's experience and improve my knowledge of the market!
