"we think that such posts are contrary to our interests as customers of IB"
Where does this come from???? I've been with them for 5 years and as far as I'm concerned the more criticism they hear the better. Maybe they will put an effort into improving things, especially now that they are publicly traded. I pay them thousands of dollars in fees and expect reliable service for their fees. For instance, this week alone I had to deal with them twice because I had not been given accurate information. Money I was told would be in my settled cash account in 3 days and available for trading took 5 days because they did not tell me that the banking dept would be closed on Columbus Day and although the $ was there on Tuesday, your buying power is based on the excess liquidity at the previous day's closing. They should have told me that when I 1st asked when the $ would be available. I was also told I could trade debit spreads in an IRA account I recently set up. But after buying the long positions, I couldn't execute the shorts. It turns out I had to apply to upgrade apply for trading permission to do spreads. Not being given full information upfront cost me $$ in both instances.
Now if you are holding IB stock I can understand your concern about criticism. Being just a customer, I think the more they hear the better.
