New Options Strike Listing Policy Weekly Standard & E-mini S&P 500 Options Only Our new strike listing policy is now in effect for short-dated options on Standard and E-mini S&P 500 futures. To optimize our strike offering to reflect customer needs, we have reduced the number of strikes in our short-term options offering and removed statistically out-of-scope strikes. Relevant strikes will remain for customer trading. This new policy applies to Monday, Wednesday, and Friday (non-third) weekly expirations only. It is not applicable to end-of-month and quarterly options.
"Phew!" That scared me bigtime. My options platform was destroyed when IB altered it's output routine, from "By Strike: Calls, Puts" to "Calls: By Strike; Puts: By Strike." Having to re-machine to take care of missing/off-stepped strikes from CBOE scared me bigly. BUT! My needed ranges are well inside the $5 ranges..... All's well!
