I've recently been obsessed with stock trading, but every time I calculate the cost of adding to my position, it's too troublesome. So I wrote a calculator. As a beginner, there might be many imperfect ideas in it. Welcome all the experts to give me some advice. 最近迷上了炒股，但是每次计算补仓成本太麻烦了，就写了一个计算器，新手可能很多地方想法不是很完善，欢迎各位大佬指点。 如果老板您觉得用的不错的话，欢迎给弟弟点鼓励，小弟先谢过了。
