Hi, we are pure ECN with access to deep liquidity pools and tight variable spreads from up to 10 major banks & lp's anytime. You can do scalping with no restriction.

It's quite difficult to choose the right broker. Jugging from experience the following will suit you: Instaforex and Roboforex. Sometimes there is a slight slippage at Instaforex but the the trading is good. But anyway it's only my opinion. Wish you profits! Good luck!
