Any brokers bigger than Interactive Brokers?

Are there brokers bigger than IB? i have traded witih mbtrading and i sometimes get partial fills on minilots.I am moving to IB and realize that i need to figure out the next step from Ib

Quite literally - Interactive Brokers is the biggest FCM in the US that offers spot Forex. IB has something like $1.5b in assets (though only a very small fraction of that is client forex funds). Other FCMs may have more in customer forex funds, but overall are much smaller. I think I have the actual numbers laying around somewhere.

That being said, the biggest doesn't always mean they're the best...

Alright - found the info I was looking for. As you can see, there are FCMs bigger than IB - Goldman, Deutsche, Barclays, etc. Though IB is the largest who have client forex funds. Near $36m

Now if you were truly looking for the FCM with the largest forex-business, you'd be looking to turn to FXCM, they have more than 10 times the amount of client funds in forex than IB does.

All this data is available from the CFTC: http://www.cftc.gov/MarketReports/Fi...FCMs/index.htm

is the margin provided by the Forex Broker?
Let us say i want to move from IB to Goldman. would Goldman provide 1:40 leverage like IB?

Depending on the volume you pull out in a monthly base , you could consider getting your own setup.
Platform, bridge if you need one for access to the market, and get your own account with a one or more Liquidity Providers.

Another alternative is to pool resources with an existing STP Brokers for access to their LP and/or ECN
for a lesser then normal commission.

Most of full service Brokers (different markets) provide around that leverage.
"Forex only" Brokers could provide more, but outside of the US.

Most liquidity providers grant 100:1 for forex nowdays.
