    I got a question for anyone with input. I sold the ENGN9 3.50P, with 9 days left and I am trying to figure out how the margin was calculated. What would your brokers charge for margin on this trade with these parameters. Sold for .03 btw, futures around 4.15. Thanks!
  2. What the hell is ENG?
  3. NG = natural gas, ENG = eMini natural gas? :confused:
    Pray that this morning's report isn't too bearish. :eek:

    ENG is just electronic NG. Whatever, does anyone have an equation to calculate the margin on these types of trades?
  5. 1) Contact your clearing firm.
    2) Find the "SPAN" page that describes margining in more detail.
    3) As a very rough guideline, for an out-of-the-money short-put, use the futures margin minus the option premium.
  6. You can come up with the margins with Ice for free. I realize you probably traded it on Nymex, but its a start. PC SPAN from CME is $500, and it looks like it is from the late 90's
