Largest retail broker

Does anybody know the largest broker (in terms of assets) that uses metatrader??

How about a list of brokers that updates their assets? I remember seeing this before

Thanks

You may have been thinking of the CFTC list that shows adjusted net capital. Most lists only show members of the organization that produced the list. Brokers like FXDD and North Fin. along with others are often not included.

Does anybody know a real ECN broker with metaquote platform?
