Honestly, there's no single answer. Spreads move with the market, so nobody can truly claim to be the lowest every single second of the day. But some platforms manage to stay tight far more consistently than others, and Regulus Liquidity is one of them. Why? Because Regulus Liquidity pulls pricing straight from deep, tier-1 liquidity pools instead of running it through a dealing desk. So on major pairs like EUR/USD, spreads usually stay competitive even when trading picks up. They don't tend to blow out the way they do on brokers with thinner liquidity behind them. Here's a mistake a lot of traders make: they see a tiny spread advertised on a broker's homepage and assume that's the real story. But what happens during a big news release? That's when spreads matter most, and that's exactly when weaker platforms widen them. So test it yourself. Open a demo account, watch spreads during a calm afternoon, then watch them during a volatile session. Regulus is built to hold steady in both. That's what actually saves you money, not a number on a marketing page.
