Cumulative option contracts include "strike price" and "strike price", and the strike price is usually discounted from the market price when signing the contract. After the contract comes into effect, when the market price of the linked assets is between the cancellation price and the exercise price, investors can regularly purchase a specified number of assets from traders according to the exercise price. When the market price of linked assets is higher than the cancellation price, the contract is terminated and investors can no longer buy assets at a discount price. However, when the market price of linked assets is lower than the exercise price, investors must regularly buy assets at twice or even four times the exercise price until the end of the contract.
