Extended data:

Option sellers do not necessarily own the underlying assets. The option can be "short". Option buyers may not really want to buy the underlying asset. Therefore, when the option expires, both parties do not have to make physical delivery of the subject matter, but only need to make up the price according to the price difference.

Due to the different trading methods, directions and targets of options, many options have been produced. Reasonable classification of options is more conducive to understanding option products.
