The choice for those in the retail market wishing to trade on an ECN (electronic communication network) has expanded this week with the latest offering from Alpari (UK). The company says its new MetaTrader 4-based platform offers users, “high-speed, low latency and direct access to ultra competitive Forex prices.” It also enables the use of algorithmic trading, or what Alpari calls “expert advisors”. On top of that, the company is trumpeting its non-dealing desk (NDD) execution and the ability of users to trade on their own bids and offers. But there is a trade off: clients will have to pay commission, which depends on volume traded.
