0 Answers: When does theta get charged for an option in trading?
Theta changes continuously because time changes continuously.
Your account is not credited or charged when theta changes. Theta simply indicates the rate at which the value of an option will change in the future due to the passage of time.
Unlike some derivatives, such as futures, your account is not credited or charged when the value of an option changes. Your account is only credited or charged when you buy an option, sell an option , exercise a long option, or when you are assigned a short option.
