Ava trade is the ECN brokers that you might be looking for. I’ve been trading with it for over 2 years now and apart from being ECN brokers, they offer tight variable spreads starting from 0.0 pips. Apart from this, another reason I opted for these two was the absence of a dealing desk and low commission of $1. All in all, it’s a good deal trading with them. But one important aspect is that you should trade on the demo accounts to understand about the functioning of the platforms.
