I shorted $ORCL weekly put , now it is going to expire worthless, do I need to buy back to close my position, or do I just let it expire and I still receive the premium? I know everything will be taken care of in my live account, I am not sure how C2 handles this.
No, you don’t need to do anything special.
If the option expires worthless, C2 will expire it for you in your system’s C2 Model Account, and you keep the premium.
If it expires in the money, you will be assigned / exercised as appropriate.
Thanks a lot for the quick reply!
