There are plenu of good systems on here that available for free. Look up the three ducks and the phil Newton break out strategies. Trader Dantes thread along with a number of threads on forex factory also provide great systems.
What I am trying to say is that there is no reason to spend a penny when learning this trade. Ask me how I know.
Self study is key.
Forex Tester is great for testing systems quickly, and is well worth the small amount it costs. A much better investment than just 1 system.
Hope this helps.
