3. Some types, such as the core trading engine of the exchange, control the trading process. If multiple types can be created, the system will be completely chaotic.

In fact, judging from my above recommendation, it is very important to lay a good foundation. In the follow-up, we will continue to read more excellent papers/frameworks, compare/practice and debug, and we will be able to make a little progress. The stage of laying the foundation must not be impetuous. If we lay a solid foundation, we will avoid many detours. Don't blindly follow the trend of worship, classics will never be out of date, reading more books/videos/excellent blogs is much better than following the trend without brains.
