I don't know whether brokers deliberately mislead on spread advertising or not. But here's what I do know...

I was using Velocity4x for demo trading and the demo has the same spreads as advertised (2 pips on EUR/USD, 3 pips on GBP/USD, etc.).

Then I opened a real account and the GBP/USD spreads varied frequently from 3 to 5 pips, but mostly were 4 pips.

So I contacted them and they switched me to another server. Now all the charts (currency pairs) have a stable spread that agrees with the advertised spreads.

I don't know what this means, so I think I'm happy, but don't know whether I should be!

Regardless, if you have a concern, you should discuss it with your broker.
