Stock Trading Fee Cost In-Depth Calculator

The A-share market has reached 2,000 points. If I don’t copy it now, I will wait until later. I will immediately take my wife to start trading in stocks. My wife is quite confused about the various expenses of stocks. But I've searched all over the Internet and can't find a satisfactory stock expense calculator. It is estimated that good calculators are integrated into the trading systems of major securities firms. Unfortunately, the calculator integrated with the trading system I used is very simple. It only shows the capital-guaranteed price. Stamp taxes, handling fees, etc. can only be seen after the transaction, and It's one way. It’s actually very easy to make this thing. I don’t know why those securities companies haven’t done it yet!
So I wrote this thing to give to my wife, who has been married to me for 6 years. Usually my wife takes care of the housework and takes care of the children. "Kiss my wife, thank you for your hard work."
