Options, “Options” in English.
It is based on the principle of leverage to increase personal profit.
Simply put, it's small and big.
Options changes, English “Motivation Option Activity”.
A change in options refers to the occurrence of a large number of transactions in a short period of time, leading to a surge or collapse in options/stocks. Since options are different from stocks, all options transactions are published and displayed on the options chain. We judge the possible surge/decline of stocks by observing changes in the options chain.
Because most of the changes in options are bought by institutions, they have sufficient information, sufficient research, and strong capital to buy, so judging the rise and fall of stocks based on the direction of the changes in options will help to a certain extent.
Changes will occur within a very short period of time. By tracking/following changes in options, we are provided with a reference for the “surge/fall” of the stock market.
