I have been following OS2 for several months and it works. Although there are losing trades, the system has been profitable every month. The pros:- no drawdown yet, though the developer claims when it does happen, it will be very small. Easy to follow system. Instructions could not be clearer The cons - a lot of trades which means checking your e-mail before the market opens and again before it closes because, depending on the futures/how the market is going, planned trades are often cancelled. Also because of the subscription expenses, trade commissions and auto trade costs, you need a large initial investment to make a decent profit.
