Appendix 2: the Diff between optionId and optionTokenId

optionId contains a single instrument's underlying asset, expiry, and strike price. So once you parse optionId, you can get the name of instruments with both call and put.

optionTokenId stands for the composition of single or multiple instruments. So it contains multiple instruments' all information and its strategy. It is an unique value and used as an actual option type of ERC-1155 format in Moby.
