At present, there is no formal listing option in China. Only some varieties have simulated trading (mainly commodity options), but there are some differences between simulated trading and real option trading. In addition, futures companies participating in the option test can see the price. So if you want to see the real option trading price, you can only look at foreign options. Foreign options, for those who can't participate in the transaction, depend on their prices, either go to the exchange where options are traded abroad to inquire about relevant data (which is troublesome) or go through financial terminals (usually payment terminals, such as Bloomberg).

If we want to calculate the option price, we have to use option pricing models, such as B-S model, binary tree, Monte Carlo and more complex stochastic volatility model. As long as the option pricing model is established (excel can be realized or other software such as matlab can be used), the theoretical price of any option can be calculated by inputting adjustable parameters. Of course, you can find some option pricing models online, but these models are not made by yourself, so you need to consider them. And usually only B-S models can be found, and others still need to be modeled by themselves.
