$Sea (SE.US)$ why?

$Ocugen (OCGN.US)$ I want to share an experience with everyone, which is when trading stocks, many people have the same problem: they don't know when to buy and when to sell. Sometimes they end up with losses even though they had profits. Now I'm going to teach you a point, but I can't guarantee that it will always be accurate or that it won't fail. Open the daily K-line chart and find the Bollinger Bands, which is an indicator composed of three lines: the upper, middle, and lower lines. Generally, when the stock price is at or breaks through the upper line, there is a high probability of a pullback. And if the stock price has been consistently below the lower line of the Bollinger Bands, there is a high probability of an upward movement. You can verify this with your own stocks. Of course, it's not always correct, but you can use it as a reference for when to enter and exit, especially for stocks that experience sudden price surges or drops. Take the stock UONE for example. Last week, many people thought it would rise but it ended up triggering stop-loss orders, while I happened to take a short position and made a profit before exiting. I'm sharing this technique with you, so please don't criticize. I'm not making money off of your tuition fees. Good luck, everyone.
