I'm considering being long

:cool:

What is the support in your opinion?

I don't deal with wheat or bean calls.. only spider options, Nothing unusual happened with my positions they were not bigger than usual that's why I was surprised . atticus -I might use wings or .. oldnemesis, I liked this link http://quant.stackexchange.com/ques...-be-short-gamma...

I have about half my money available as what they consider - available Option buying power . But now they added another criteria " when stressed up or down 20%, now represent a theoretical loss of more than double the current equity in your account.." There is a difference between...

I have a portfolio margin in TOS , I'm well above with the Option buying power and then I receive this Email : Hello Mark, We are writing to inform you regarding an increased option exposure in your account ending in ****. Your various positions, when stressed up or down 20%, now...

What are the Best Brokers on Portfolio Margin ? consider also the rates.. There is IB , TOS and..?

as far as I know they don't

After speaking with TOS , this is their answer : we use to have the requirements on the thinkorswim.com website, but it looks like we need to incorporate that information on the tdameritrade.com website as it is no longer on the TOS website. here is the information that you will need...

Unfortunatly - after joinning TD I can't see this section in their web site. I would ask a representative on line about it . :confused:

I have to thank ids who explained to me several points I was not aware of. I think it is probably difficult to produce a specific calculation on a trade but there must be an inbetween option of knowing some of the basic rules that are important to the Broker . at the moment there is...

You would think that they are obliged to publis these requirements but it seems the opposit - both TOS and IB and no other Broker I know of - don't specify and publish a clear Margin Guideline that will specify what are their requirements .. I realy don't know why ..

I totaly agree with you , but when I tried understanding those restrictions in TOS with the person in charge I had the feeling he knows less than me or he doesn't want to reveal those specific requirements ..

Thanks , it's like driving a sports car with out having control on the steering wheel . this rule I know but the TIMS formula or whatever they use is more complex than that ..

I know they use the TIMS in general but it is almost impossible to understand and expect the Fluctuations of the Margin . Is there someone who understands the Black Box ? thanks :)

If you have a link - I would be glad to receive it . I don't mean the general explanation but a more detailed used by TOS,TD,IB etc. Thanks :)
