I have tested a couple of systems from Russ Horn and I'm very mitigated.
The TradeOnix is very bad in my opinion. It gives very late entries, and almost no real opportunities, I've blown up an account with the "trade assistant". However, he recently released some new systems which have given me very good results (the Anvil one).
I'm joining you the Forex Strategy Master, let us know if you find any good results with it!
