Brokers that offer both 4 and 5 digit MT4 Demos

Does anyone know of a broker that offers a Demo MT4 accounts in both 4 and 5 digits?
I'm trying to evaluate the effectiveness of my EA at 5 digit [see if it is working right], but to get an honest test, I should really be using the same broker feed.
Right now the EA on 5 digit is not performing nearly as well as the 4, but not sure if it is a coding issue or just the difference in the brokers price feeds.

Thanks
