The thing about exchange rebates is that manually calculating them can really drive a person crazy.

The most ruthless operation I've seen: the product manager can't even write code, yet handed a bunch of requirements to Cursor, and within ten minutes, the commission calculator was done. Import the Excel spreadsheet, the system automatically runs the data, and it's clear how much rebate to issue; the rest is just transferring money according to the list.

Now many platforms directly offer an 80% rebate, saving the hassle of back-and-forth algorithm adjustments. But the core still lies in that logic – delegating repetitive tasks to tools, while humans are only responsible for the final decision.

In this day and age, it's not important to understand technology; the real skill is knowing how to use tools to improve efficiency. Code is something that not only changes the way development is done but also enhances the operational efficiency of the entire industry.
