About the calculation of stock costs

Hello, I would like to suggest a product optimization. In the process of buying and selling Hong Kong stocks, there are various fees involved, including platform fees, third-party charges, etc. These fees are charged in both directions and cannot be ignored when calculating the cost of stocks. I hope to add a feature toggle that, after a stock transaction, displays the real cost per share including all taxes and fees. This would allow for a more intuitive understanding of the actual cost price, as taxes and fees are real expenses. For example, mainland China's Tonghuashun has this feature. If you buy 100 shares at 1 yuan, the displayed cost is not 1 yuan but slightly more, indicating that you need to sell at least at that slightly higher price to break even after accounting for both buying and selling fees.
