Some Forex Brokers

It would be unfair to name the Brokers that have a discrepancy in their price feed because

their price servers could be updated at any time and we don't monitor their speed

or services.  However, if the Broker is offering "unlimited' demo accounts to anyone

that has access to the internet than you should question the demo accounts synchronization.

If you ask the Broker, they tend to say that the demo platform is identical because there is a

negligible difference by their standards. But if you compare their demo data versus their 

real data...it does differ!  This can have an impact on back-testing results for forex traders and

 "scalpers" but less impact on long-term traders.
