I never said there is zero chance but you did call the firm dishonest and I don't see that in the way the conduct business and practice what they preach. Your fixation on order flow and twisting the wording of the 606 reports is my issue. I personally think there are a number of brokers who are financially exceptionally strong and don't mess around - Fidelity and Schwab come to mind along with IB. I'm no apologist but I do like to call a spade a spade when I see one.
If you disagree with my assertions about order flow, then that thread is probably the more appropriate place to discuss it, no?
Do a quick search here and you'll find dozens of cases of IB reps flat out lying to customers. I've had that same experience, a couple of examples off the top of my head; I was told that IB charges margin above the debit amount on a vertical debit spread for ES FOPs because they're required to by the CFTC. When asked which regulation or law they were referring to they told me they didn't have to provide me that information. When asked why several other brokers I know of didn't charge this margin, they doubled down on wrong. Of course they are incorrect, but they refuse to admit it, when the easy answer which happens to be the truth as well is "we programmed our algorithm to evaluate each leg of a vertical spread separately without taking into account that it is a debit spread that can't lose more than you initially paid for it. We don't feel like fixing the algorithm, sorry".
Another example, I wasn't seeming my ES vertical spreads inside the bid/ask reflected in the quote. When I asked why my spreads weren't showing up on GLOBEX, they went through a whole litany of lies. First it was ""Spread orders on Globex such as your ES order are not displayed on the IB Trader Workstation (TWS). Globex is a market place which accepts orders and creates requests for quote which are seen by all market maker participants with access to the book. Futures market makers are not required to disseminate continuous bids or asks."" (that's their exact quote). They stick with this over 2 phone calls and 2 emails. Of course CME itself claims "CME Group electronic markets provide an entirely level playing field for all participants. Individual retail traders, small businesses and large institutions alike see and have access to the same prices. The anonymity of traders and firms is protected electronically in all
bids, offers and trades." (
http://www.cmegroup.com/globex/files/GlobexRefGd.pdf), so who's lying here?
When that is pointed out, they pivot to "Spread orders on CME exchanges, such as your SPX spread, please note that spreads that are less than 10 contracts are booked electronically and will be displayed however, spreads that are greater than 10 contracts are handled at the broker's discretion." (again actual quote) So I book an order for 9 contracts and guess what, still doesn't show up.
They then go with "All ES spreads are handled at the broker's discretion". This was probably the correct answer all along? but note how it is mutually exclusive with their first explanation, so one of them had to be a lie.
Heck even the IB rep that used to frequent this board before they ran away was always twisting words, check out the thread on if the stock you lend under their lending program is covered by SIPC insurance if you want to see a great example of word twisting given that you seem concerned about that.
Are these egregious enough to warrant legal action, probably not. Do they indicate a culture of dishonesty? Absolutely. Does it mean IB is cheating on their financials? Probably not, but as you agreed there is a non-zero chance they and any other broker are. Bullshit about their margin rates, how reputable they are, and how much their CEO has to lose are relevant how again? A corporate culture of dishonesty actually is far more relevant, wouldn't you think?
