Quote from Jason Rogers:
The same is true of brokers registered in the US by the NFA. The execution method and details will be listed in the trading agreement.
Quote from JR-Welling:
All fx brokers are counterparty. It doesn't mean they are a dealing desk.
For example, lets say a broker provides a platform of best bid / best offer liqudity of 6 banks.
When you trade you are hitting the bank's bid or offer. However, the broker is counterparty your transaction and counterparty to the bank's transaction.
Is just a back office reconciliation item. Nothing more than that.

Quote from Gcapman:
I'm currently at FXCM with a mini-account so all my trades are against the broker - so how do I know when my account is switched over to regular status (aka commission)?
