Going long in the futures market means signing a contract with others to buy (goods) (if you don't close your position at maturity, you have to accept the spot, and the person who shorted at the beginning is responsible for the appearance of the goods), and then buying a short option in the option market, which is the right to buy (goods) at the agreed time and in accordance with the agreed price and quantity.

When the futures price rises, the futures you buy make money, and the short options you buy are unprofitable, so you can give up the exercise (wasting your strength).

When the futures price falls, the bought futures lose money, and the bought short option is beneficial to exercise, which can make up for the futures loss.
