You will find a pure ECN broker easily on the internet. Just make sure you go with the right one and are not scammed out there. Try to trade with brokers that are reliable, have a reputation and are regulated. Good luck to you.
I prefer trading with an ECN pricing broker because they offer tighter spreads than regular brokers. I currently trade with FP markets using their Raw ecn account, the spreads began at 0 pips in EURUSD currency pair.
