I'll look for opportunities to gradually clear out these small tickets later.$MP Materials(MP.US) has dropped so much that even its mother wouldn't recognize it. They said self-reliance and controllability were guaranteed, but it seems the US version isn't as resolute as 'Dongda' (China)! For me, trading US stocks this year has been harder than last year.I missed out on a 300,000 income in May.I can only comfort myself by saying it's good to learn lessons early, and there are indeed many areas for improvement when combining with the A-share market.There are also far fewer bright new targets in the US stock market this year compared to last year, possibly because AI development has entered a certain stable period.Energy, space, chips, new cloud computing, self-reliance and controllability—those that should have been realized have already been realized.

How to set stop-losses for reversals (buying at the halfway point or peak).2. The program cannot see the entire trend like human eyes do. In a major trend, how to avoid being washed out by minor pullbacks (taking profits after a 10-25% or even 40% drawdown might cause you to miss subsequent 2-3x gains).Besides percentage-based take-profit and stop-loss strategies, I've added the option of an ATR strategy. I'm preparing a paper trading account to run it for a few days. Consider it learning about various technical indicators and quantitative methods through the program.If the reversal take-profit and stop-loss issues can be resolved, the program's win rate will significantly improve." datetime: "2026-07-25T03:19:45.000Z" locales: - [en](https://longbridge.com/en/topics/42934571.md) - [zh-CN](https://longbridge.com/zh-CN/topics/42934571.md) - [zh-HK](https://longbridge.com/zh-HK/topics/42934571.md) author: "[不奋东西](https://longbridge.com/en/profiles/14442740.md)" --- # On one hand, AI's development is indeed unstop… ### Related Stocks - [MP.US](https://longbridge.com/en/quote/MP.US.md)
