A good choice with ECN there. You will find lowest spreads there, pricing is always competitive due to choices by liquidity providers. Fxview and Xm are the 2 that I am using currently, and both offer ecn accounts, in fact fxview offers only pure ECN. Commission cost is low at a dollar for one side, and spreads can get low as 0.0 pips on major pairs. IC Markets is another broker you can look at for low spreads, 0.1 pips average.
