OTC options (generally referred to as OTC options, which can also be translated as "OTC market options" or "OTC options") refer to the trading of non-standardized financial options contracts in non-centralized trading places. One party of OTC options usually designs OTC contracts according to the specific needs of the other party. Usually, the proposer is called Party A. The main difference between on-site options and off-site options lies in whether the option contract is standardized.
