IB's rules maybe arbitary , but it's a business transaction , if we don't like their rules we don't have to trade with them, most brokers will have some rules, I just find I lose the will to live trying to work out margin reqs every day so don't bother, I bet even if you follow all your advice on margin you'll still occasionally find differences where IB have changed the reqs etc.) (especially with more obscure stocks etc)
Maybe true , but I think with cfd's in particular their commissions are much much less than other brokers, especially U.S. stocks , certainly Uk based cfd's are I believe twice the commission atleast (I'd be happy to be corrected on this ) probably the thing that comes closest would be portfolio margin with other US brokers.
You know why CFD's commission are lower? That's cuz the broker is the market maker of the CFD's so when you are trading in those CFD's, you are trading against the broker itself so whenever you lose, they win. They are directly profiting from your positions so this is why they charge you lower commissions. And you can only profit when they lose. Guess what they are going to not let you do?? For me, I wouldn't trade CFD's at all with any brokers.
I would keep away from IB, their margin requirements fluctuate wildly and I'm seeing worse terms for CFDs, never mind the execution issues. IB's risk department treats traders like sheep.

By the way, I just downloaded demo and I don't see 30% limit thingy there. Buying power is less than 10x for blue chips, but certainly not 3.3. They advertise that the demo is the same as real TWS, but I'll call them to be sure about this.
To me, this is just how IB micromanages its traders by imposing its own arbitrary rules and policies when they are totally clueless about the nature of the market nor the quality or behaviour of the security itself nor the trading skill and prudence of the traders themselves. I have opened up an account at IB to trade, not to be babysat. It's both draconian and baseless. What's this "30%" based on? Why not 20%? Why is not 50% or 100%? Why don't they the security will drop in value 100% while they are at it? Why stop at 30%? If you are able to find other brokers, I strongly suggest you go with other brokers. Take it from a former client of IB who has been with IB for many years, trust me when I tell you IB is NOT what it makes itself out to be. It's neither the lowest-cost nor the best quality broker out there. Their advertised commission charge might be low but they have all kinds of mechanisms and hidden fees/charges to make sure your commission charge that you end up paying is higher, much higher than what is advertised. Your experience with them will be a very frustrating one. You can ask many of the Elite Trader members here who are truly IB's clients and they will tell you the same thing. They are many many many brokers out there that are either lower cost or deliver much better quality of platform/service/execution or both or all of them or at least 2 or 3 of the criteria. IB is really a high-end bucketshop that just dwindles right on the edge of the legal side. If you still want to try them out, go right ahead but you will arrive at the same conclusion as us.
Good luck!
Long on emotional paranoid rambling, short on facts and data.
Can you give even one proof of a trade that you did where the commission fees were different than what is documented on their website?
Can you actually name some of these "many, many" other brokers that are superior to IB and quantify the ways in which they are superior? I'm sure that there are literally tens of thousands of people out there who would love to be enlightened on this, myself included.
Can you back up your assertion that IB engaged in legally questionable practices?
