Best all-round futures broker for small UK professional trader
Overall 8/10 (9/10 if they get rid of 'cancellation charges')
Pros:
Wide selection of products available to trade on global markets
Competitive commissions eg. $4.02 per RT for S&P Emini. You can get slightly little lower (I've seen $3.30 per RT) with some US based discount brokers , but IB still blows away the abysmal $7 per RT offered by MF Global / GNI Touch, or other rip-off brokers. Shop around!!
TWS (Trader Workstation) trading platform is free, and very reliable, not buggy - it has many features if you dig deep, and you can also use a different front end if TWS is not to your taste. It suits me fine.
Free-ish data feed...provided you do a minimum level of activity...though not a 'pure' data feed as IB filters data in 250 ms packets, this is still good enough for the naked eye given the time it takes for a human being to react! During busier periods when activity is high (non farm payroll release) this probably makes the IB data feed more reliable than a pure data feed. You can pay for a different (pure tick by tick) data feed if you prefer, such as eSignal, etc. I don't feel the need, though for backtesting, automated trading you'd want this.
Many front end platforms compatible with IB. Large community base.
Universal account - others have reviewed this feature...
Website has a lot of documentation to explain details, and there are
also regular webinars to explain software, product releases, etc.
Big, profitable company, listed on exchanges, so I feel safer keeping my money with IB than other brokers.
Cons:
High cancellation charges in certain products (eg Eurex futures such as Bund, Bobl), whenever you amend/modify an order - this can double/triple your effective commission charges if you keep changing the price you are working! IB, please get rid of your stupid cancellation charges!!
Modest charting functionality - if you open too many charts it might slow or crash your PC. It's useable - I coped for two years - but I now pay monthly for dedicated charting offered by Sierra Chart and it complements IB TWS nicely.
Account statement is very detailed, but somewhat confusing (for me anyway!). Took me ages to work everything out in a spreadsheet.
TWS platform probably not too 'user friendly' for the inexperienced trader
Customer services had a bad reputation in the past, though I've personally had no problems, they have been helpful and polite. But IB is not into hand holding, so if you are a novice, probably better to look elsewhere and pay higher commissions for the better customer service.
