Forex Avenger offers a Forex trading system (sort of a guide) that will teach users how to trade better (given that they follow the advices given in this course and that the market follows the trend that the course mentions it's good to trade at). The website offers several testimonials along with other long explanations giving an idea on how this trading system works (though it's the sales-letter type of website).

Forex Avenger offers an affiliate program that gives you a 60% commission for each generated sale. The price it sells for is $100 (actually $97), meaning that you can earn up to $60 per sale. They don't mention anything about referring affiliates, so probably no 2nd tier affiliate program available.

The affiliate program is powered by Clickbank, so you would need an account with them in order to start promoting it. You can read more about it here: Forex Avenger course
