By definition we are classed as a market maker as the majority of FX providers are, however we do not operate a dealing desk and simply pass all trades through to hedging partners. There is no spread widening or stop-hunting etc.

Go Markets say they allow scalping and they are ECN but my experience is as follow:

Used demo for over 2 months, fast and spreads where good 0.8 to 1.6 during EU and NY sessions. Made excellent profits following my scalping strategy. Then as soon, and I mean as soon, as I opened the live account and started scalping latency and slippage problems. And of course it was my firewall's fault. I am in IT and firewalls do not mess with a program you once you have set permissions. Platform is the same what changes is your login and password but the program retains permissions.

This is the script bucketshops read to scalpers in the hopes that once you opened the account and find out you can't possibly make money with your set scalping approach that you'll change strategies and try to make you money back thus prolonging the inevitable. Then after loosing a great portion of our money you go away. I seen this happen with two traders and it happened to me once before. It is their modus operandi. That's why now I open with a small amount and test them.

For a scalper who looks for less than 10 pips in each trade a frozen feed is mortal to your strategy. It also increases your loss ratio since you are increasing the odds of getting our of a bad trade.

GO away from GO Markets is my advise.
