Choose a virtual contract according to the ups and downs (if the premium is low, the leverage is high, the general trend is accurately grasped, and the contract will rise and fall more)
Look at the small ups and downs and choose a moderate real contract (moderate royalties can better capture the profits brought by small changes in the price of 50ETF)
It can also be seen from the ratio index of T quotation of SSE 50ETF options that real options include intrinsic value and time value, while hypothetical options only have time value, so real options are also called in-price options and hypothetical options are also called out-of-price options.
Real options are valid when they expire, and virtual options are invalid when they expire. Therefore, option investors should consider whether to exercise in advance before the option expires. If you can't exercise your rights, stop loss in advance and recover the remaining royalties.
