Do you have other AAPL positions in your account other than the iron condor? that could affect the margin use

Can you show a screenshot? I don't use TOS, but maybe I will make an account there if it can help with modeling the margin.

But you can still survive getting stopped out 24 times with a $0.02 stop loss and still breakeven. edit: maybe only 12 times with slippage and commissions.

Are you short the underlying AAPL, then closing this condor could make the margin use go up, as the condor is protecting your short position.

The usage I quoted was for IBKR, shows which is 2x TOS which must be 20% down. I am still not sure how much more is used if the market moves down by 2% does that mean I use 10% more margin?

Does anyone have a way to model this? For example 10 naked SPX 1700 puts, uses ~124,000 margin. How do I find out how much margin is used the next day, for example how much less used if the market goes up, and how much more used if the market goes down, by 1%, 2% etc.? I can't really...

polltard - those aren't the only 2 options.

IBKR does not charge for exercises or assignments.

yes. the details are on their website, under commissions. My own analysis suggested you need 300k or 1M volume/month to breakeven depending on the product/exchange, then you start getting rebates.

the NYSE data is available for free at IBKR if you have an account.

Did anyone do this for the new form for either 2013 or 2014?

1) TWS bug-- If you have a GTC order filled over multiple days, the commission reported in the TWS is incorrect. 2) suggestion-- would be nice if the T&S window showed the subpenny orders routinely, and also had an option to list the exchange of execution. It is annoying to have to go to...

I am not sure if this is the exact answer but it is related. I had a whole bunch of option orders open, then when I filled one, it automatically cancelled another one for margin restrictions.

The lawsuit was that he used schedule C to deduct his margin interest instead of schedule A.
