Quote from MTE:
I don't trade those, so anyone with more accurate knowledge please feel free to correct me, but given that the underlying for Sep options is the Sep futures contract, which expires on the same day, the options will settle into cash not a futures position.
Quote from benysl:
thank you how about a Oct position??
Emini S&P futures December contract expire in December.
Short a Call 1280
On 20th Oct friday Dec S&P close at 1300.
Will I be long 1 contract on the following monday? At what prices??
If it is cash settle I presume it will be at 1300??
Quote from cohenmichaela:
Options contracts for the March Quarterly cycle (Mar, Jun, Sep, Dec) will be settled in cash. Serial options for other months are settled with the closest ES contract. In your case the short OCT 1280 Call will make you short the ES @ 1280 (ES currently @ 1300) at expiration.
