Quote from IV_Trader:
Sorry , forgot to mention its ratioed , simple DN. Short 100 shares + long 2 calls (if delta is 0.5 ).
In this case I am paying just difference in rates. Cheaper when comparing to long straddles/strangles or long stock + long puts combo.
I'm not really sure what you are saying, but there is no such thing as PM "recognizing" something or not. PM is simply allowing the retail trader to have access to minimum margins like a floor trader via the OCC's TIMS system. The PM requirement for a short calendar is just the max loss the position will theoretically have using currently implied vols over a standardized percentage move depending on the underlying.Quote from IV_Trader:
Looks like PM doesnât recognizing accumulation of deltas for 1:1 short calendar position. Did anyone tried to get deltas flat via selling (or buying) stock? How did it affect margins?

Where are you trading? It may be that the firm is charging you more margin because they want to, not because of PM.

As a matter of fact, PM is less restrictive (+6%/-8% for SPX; +10%/-10% for NDX) than a JBO prop shop (+/-10% SPX, +/-15% NDX).
Since I have not talked to every JBO in existence I will admit I was generalizing but since Bright, ECHO, and Generic all make you cover the JBO haircut I figured it was at least a relatively accurate one.Quote from Maverick74:
Opt, this is true on paper, but in reality, most JBO's let you have much better margin then CPM. Just because the risk thresholds are +/- 10% and 15%, does not mean that JBO clients are restricted to that.
