IB is the 16th largest securities firm in America...
And according to their latest posted financial statement...
One can do some very approximate analysis:
http://www.interactivebrokers.com/download/IBLLC_1Q06_Unaud_Finls.pdf
So IB has about $3 billion in customer accounts...
And $270 million in Net Capital (roughly liquidation value).
Also, most customer accounts are fully insured.
Obviously, the futures business with only about $100 million in customer funds...
Represents a small part of their business... maybe 5%.
The action posted to start this thread should NOT be a cause for concern.
Also...
You can check the regulatory history of any firm here:
http://www.nasd.com/InvestorInformation/InvestorProtection/NASDW_005882
It's free...
And the NASD will email you a report going back 10 years or so... in about 48 hours.
But you really must have regulatory experience to properly evaluate a firm's history.
ALL firms the size of IB will have many minor infractions...
Such as "reporting" violations or "supervision" violations.
But you do not want to see a pattern of organized deceitful behavior...
Like, for example, organized cheating by Specialists or market makers.
If you see that... I guarentee you it comes from the top.
*** It's important to understand that many issues are in a "grey area" ***
Especially highly technical issues.
The thing about an uber-computerized leading edge firm like IB...
Is that they are always walking a fine line between automation and compliance.
They are always pushing to see what they can get away with when automating...
And will be occasionally be told to program things differently (and possibly fined).
This is not necesssarily a bad thing...
Because by pushing the envelope... IB has brought costs down for all of us.
