There are three categories of trading systems, trading logic systems, signal filtering systems, and execution operating systems.

The transaction logic system is aimed at the ideological and cognitive level. Is there an end point?

There is an end.

The unity of nature and man, governing by doing nothing, is the point of view of Taoist philosophy. This is Confucius's point of view. Xiaoyaoyou This is Zhuangzi's point of view. When people return to the ontology of materialism, that is the end.

The signal filtering system is aimed at the price disk. Take a series of corresponding actions based on the objective signals given by the price and achieve profits. All objective signals used in this process are collectively called a trading system.

The so-called optimization is to remove some redundant actions without affecting the overall profit results. This is called optimization.

Open a position - stop loss - take profit, these are three actions, corresponding to three signals. What is the end point of optimization? When the signal is unique, it is the end point of optimization.

An opening signal, a stop loss signal, and a take profit signal. Three signals correspond to three behavioral modes, which is the end point of signal filtering system optimization. There is no way to streamline it any further.

The execution of the operating system is for the transaction process. Robotic programmed execution is the end point. What is the next level? there is none left.

In summary, a conclusion is drawn.

The transaction logic system, the signal filtering system, and the execution operating system will eventually overlap on a straight line.
