Hi Nicholas,
Petko says the FTMO Expert Advisors can be used on other prop firms and he has passed challenges with other prop firms. Personally, I only have experience using the Expert Advisors with FTMO and Infinity Forex Funds. Also, there are several traders complaining the Expert Advisors are not placing trades on other prop firms. My suggestion is to stick with FTMO Challenges until you get funded or use Infinity Forex Funds. This way you will not have any problems with the Expert Advisors trading.
Alan,
