Hi @BaconSandwich,
Under NFA Compliance Rule 2-36, any US-regulated broker must provide you with transaction data upon request for the 15 forex transactions in the same currency pair occurring immediately before and after your transaction.
We discussed the requirements set by the CFTC and NFA for US-regulated forex brokers in more detail in this earlier post: Canada now the WORST place to be Forex Trader & kiss overseas Broker goodbye
