Zero spreads are not possible at all times, there are certain market conditions when spreads reach 0. I’m fine with the spreads offered by aaafx and avatrade. Commission is also on the lower side.
For lower spreads and commission costs, I recommend trading with FP Markets because it offers lower commission costs than other ECN brokers and when trading with EURUSD or other major pairs, the spreads start from 0.0pips with an execution speed of 80ms.
