Is Forexpeacearmy.com reviews accurate about anything to do with forex under reviews and ratings?

I need to know where to find a place to find accurate reviews of Forex signals, managed Forex accounts and Forex robots?

No not at all, Anyone can leave a review, good or bad. so what you get is every broker and affiliate leaving good reviews for their broker and bad for the other. Like any other website Forexpeacearmy is just in it for the money. Trial and error is the only way you will find what you are looking for and end up with an honest opinion.
