    By extention, interest is paid on any position that is net credit, such as short verticals and IC's, right? Thanks in advance.
  4. Correct, any net increase in credit balance. I liked the rhyme.

    :) and thanks again.
  6. Not only do they pay, the current rate is 4.313% (!), much higher than, say, thinkorswim.
  7. Actually, I don't think that IB pays much interest on the credit balance from short stock sales. As I recall, on the first $100,00 no interest is paid.

  8. That's not quite correct. 4.313 is the benchmark rate and they pay a little less than that depending on the actual balance. For example, between $10,000 and $100,000 they pay benchmark minus 1/2% which is 3.813%. On the first $10,000 I don't think they pay any interest.

  10. Does anyone know what the margin requirement is to sell a naked put on ES Jan 06 with a strike of 1200, for example. I know the SPAN system is used, but is there some sort a approximation that you can use to get an idea?
    Securities options seem to be at least 10% of the underlying value. I'm not clear on whether futures options are lower.
