From my experience, the lowest spreads usually come from brokers with ECN or raw spread accounts, but you really have to look at the full picture. I’ve compared a few options using different sources, and checking platforms like Vetted FX Brokers
helped me understand how spreads differ depending on account type and market conditions. When I switched to a broker with tighter spreads, it didn’t magically boost profits, but it did make frequent trading feel more efficient and predictable.
