If you need a ECN/STP/RAW account which offers very tight spreads, you will have to pay commissions. That's how the brokers make money.However, comparatively speaking i''m trading with FP Markets as they have some of the tightest spreads and they only charge 6$ per round lot compared to other similar brokers who charge 7$ as commission. If you join under a IB partner you can even get it for around 5$ commission i believe.
