Fair and that is what I mentioned in my post right before. Some may only trade ES futures , for them IB's platform is overkill. And I mentioned now multiple times that spreads ought to find their happiness elsewhere. IB does not want their business. It is pretty obvious.
Hmm. I think you may be getting some wires crossed here. Not every trader requires a "portfolio margin account". So maybe IB is good for that sort of thing, and other brokers are worse. But perhaps other brokers are better at other types of account than IB is.
