    I'm looking for a margin calc that will show me what my margin will be for a multi symbol, multi leg spread. A simple spead calc won't work I need something more advanced. I can't believe how hard it is to find... if anyone could help I would appreciate it.

    Cross underlying margining only matters if you use portfolio margining or SPAN. For portfolio margining you can use this one. As for SPAN, there is no free calculator.
  3. u could theoritically open a thinkorswim. paper trading account and when u try to place a trade it will tell you how much margin you need to sell a put/call

    but this is dynamic. .when the position moves , the margin required also moves.. but for a ballpark it does help..

    ex.. BIDU. selling OTM 580 Strike naked calls, need approx 8-9K margin
  4. Go to www.cboe.com they have margin calculator..Look under tools.
  5. It depends who is your broker.
