Quote from Maverick74:
I stand corrected. IB is exempt from PDT, Fimat and TOS is not. However, I did notice all these added restrictions at IB on top of the PM:
A market-based stress of the underlying. A five standard deviation historical move is computed for each class. This five standard deviation move is based on 30 days of high, low, open, and close data from Bloomberg excluding holidays and weekends. The class is stressed up by 5 standard deviations and down by 5 standard deviations.
An implied volatility stress for options. Each options classâs implied volatility is increased by 15% and decreased by 15%.
In addition to the stress parameters above the following minimums will also be applied:
Classes with large single concentrations will have a margin requirement of 30% applied to the concentrated position.
This is a huge penalty for those whose positions are all concentrated in SPX, RUT, etc.
Also, the second your account drops below 100k, your account immediately reverts back to Reg T. Oh, that will be fun for some. The margin calls this is going to produce will be fun to watch. LOL.
Perhaps there still are some minor advantages to having a JBO - but they are minor (ie. my margin requirement just fell about 94 %)
Should be fun............
