One of the biggest differences you will find with the Millennium Trader 4 are the price feed quotes. They are responsive and they reflect where the market is trading. Through Millennium Trader 4, we have concluded an agreement where we are able to offer our clients a live forex feed that comes directly from a large international bank.

Here are the main features of the Millennium Trader 4 platform:

• A true, responsive inter-bank price feed without price-shifting. 
• Automatic, fast execution on trades up to 30 lots without human intervention. 
• The ability to execute a trade at a quoted price is limited only by the speed of your internet connection. Re-quotes occur only if the price has actually changed from the moment you place your order and we receive it. Traders receive a new quote of the inter-bank rate without price-shifting. 
• A Dealing Desk that is open from 21:30 PM Sundays to 21:00 PM GMT Fridays.
