I'll come again tomorrow depending on the situation.

Ricordare : Why is the cost negative???

韭菜炒蛋黄 : You bought 1,000 shares for 100 yuan and sold 950 shares for 115, so the cost became negative

顺顺顺 韭菜炒蛋黄 : 还有这样的？

Crown Clown 顺顺顺 : Yes, I've done it before

顺顺顺 Crown Clown : Got it, got it, I want to make it all out

Crown Clown 顺顺顺 : No, for example, if you buy 5 100 dollar stocks, or 500, then after the stock rises to 300, then 5 tablets become 1,500. After that, if you sell 3 tablets, it's 900 US dollars, and you have 2 tablets left. This means that you have already recovered your capital and the remaining 2 tablets are earned as a package

顺顺顺 : Oh yeah, that's what I understood before, thank you
