I emailed Chris, the author of this very informative article: http://tradesight.com/wordpress/?p=46 asking how I can tell if a broker has a dealing desk. He said if they have [fixed] spreads, they have a dealing desk. http://mbtrading.com/fx/ was the broker he recommended, and he has a relationship with their company. MBTrading FX gives you the ability to profit on as little as 1 pip market movements. You also get to see Big Bank volume, not just Broker volume.

I consider Metaquotes to be a prototyping system really When I get serious all of my trading systems will be DLLs running under both MQ and the MBT SDK.
