I'm currently using Reg -T margin on all my trading and have no qualms about it. However, I have now become eligible for portfolio margin. So the question is do I use it or not?

For anyone using it now or have used it in the past, some opinions on the pros & cons would be greatly appreciated.
 
Hi mazza,

Can i assume with portfolio margining XJO options and SPI futures can be cross margined or does this only apply to the US markets ?
 
Grinder,

Frees up capital => turnover of inventory > efficient.
Cross margining is a function of this e.g. SPX options can be offset against DIA options

The danger is taking on too much leverage than your account can handle
Too many short more strangles :D

IOW you should apply for it

Hi cutz,
As far as I'm aware, for what Grinder is referring to, it is for US derivatives.
You should ask IB. I just had a read that portfolio margining will depend on how ASX monitors it.
 
thanks for the feedback mazza, it's pretty tempting :) Will most probably ease into it & initially trade as if i don't have it, however I can't seem to find anykind of modeller though to give me an idea of how much better the margining could get, will hunt around to see what I can find.

Portfolio margin is based on SPAN. It's pretty complex and obtuse, but you can buy PC-SPAN from CME for about $500.

Here's some stuff from CBOE on it http://www.cboe.com/aboutcboe/special/marginexamples.pdf
 
I watched a couple of webcasts on the benefits of PM & like what I see. Thanks for the link Wayne, found a simmilar one below (margins on ICs using both sides instead of one side)

also found this modeller but it's not very useful

Do you think PC-SPAN is worth getting?
.

I haven't got it, but never push to the edges of my margin. Only necessary if you *NEED* to know where your exact margin is at.

I just make an educated guess. :eek:
 
I've been doing alil of that guestimating with % moves & figure an otm IC on PM can be reduced to about a third of what Reg T would be, & if I chuck a bit more on the wings could even get it down further :D
