Currently if we want to roll over a put option to a later expiry date, we need to buy back and sell a new put option (at a later expiry date) manually in two steps. As time is crucial in option trading, I suggest we allow roll over an option to a later date in one step. This can also be extended to roll over a sold call option.
The advantage is it makes trading options more efficient and Moomoo can also attract more customers who likes to trade in options.
