Can anyone provide a reliable resource for determining artificial and abnormal pair moves?

You mean stop hunting? All you need to do is have the trading platforms of several brokers handy for comparisons. For example, during the previous NFP trade, I had almost the same price at the end of the initial rally between North Finance and InterbankFX. Neuimex on the other hand had a price up to 38 pips lower than both NF and ibfx for several minutes! That Neuimex client is now with NF

with mt3 api u could make a program that logs into there demos and checks all prices from brokers using mt3 and the if one deviates far enuf from the others have an audible alert or maybe even auto posts these dates and times to a webpage. or perhaps you could take advantage of it let say if one spikes long do a sell and close when it normalizes to the others or they catch up. assuming that one would ever deviate hard enuf. just another thing on my compunding todo list :/ Although with a little creative programing I believe you can get around them. When i work on an expert i program to fight the market and i program to fight the dealers who may altar things a tad to make the banks happy.
