Consultation on futures issues
My understanding:

If you buy a put option, it will be an empty order if it falls, and there will be no risk if it goes up, with a cost of 5.5.

When selling a put option, if it falls, it means more orders, and if it rises, it will lock the profit at 4.5.

So these two completely hedge, losing 1.

Buy futures, one more order.

If the maturity price is (428.5,430), the profit is 1.5- 1=0.5.

Assuming the maturity date is X, the profit and loss should be equal to X-430+0.5.
